Sicelo	well ... Zungo was right about Windows .. i connected it to a machine in the office (but i have no admin permissions on it, so can't install Odin)	00:17
Zungo	Odin is not something you install sicelo	00:17
Sicelo	but this windows thing is making me wonder if i want to go ahead with this ROM business	00:17
Zungo	its just an app	00:18
Sicelo	mmm	00:18
Zungo	you'd also want to have a stock rom too	00:18
Zungo	in case of problems	00:18
Zungo	or giving away	00:18
Sicelo	and windows	00:18
Zungo	restoring stock also resets the tamper flag	00:18
Sicelo	that's the hard part	00:19
Zungo	yeah, heimdal is beta	00:19
Zungo	you need admin for devices communication also	00:19
Zungo	one more thing	00:19
Sicelo	still doesn't explain why the phone is not detected on linux ...	00:19
Zungo	check your usb filter	00:19
Zungo	that might	00:19
Zungo	tried another computer with linux?	00:20
Sicelo	i think i'll remain on stock. the samsung's job is whatsapp only anyway	00:20
Sicelo	Zungo: yes, pc and laptop	00:20
Zungo	touchwiz sucks	00:20
Zungo	you maybe want to use odin once to root it	00:20
Zungo	and remove knox	00:20
Zungo	and bloat	00:20
Sicelo	you say odin doesn't need install?	00:20
Zungo	its a leaked app	00:21
Zungo	simple	00:21
Sicelo	and what's a leaked app?	00:21
Zungo	but it does require admin privileges because of driver interaction	00:21
Zungo	Odin is leaked software	00:21
*** buZz has joined #maemo		00:21
Zungo	it's a internal samsung tool	00:21
Sicelo	so yes .. i can't run it on the windows machine i tested on	00:21

DocScrutinizer05	Sicelo: settings developer options "allow kernel unlock" or somesuch, maybe?	00:22
Zungo	DocScrutinizer05: that's only on 6.0 onwards or something	00:23
Zungo	and he tried a windows machine which worked	00:23
DocScrutinizer05	yep, possible	00:23
Zungo	samsung S4 gets no more updates	00:23
Zungo	latest stock rom is 5.0.1	00:23
Zungo	based on*	00:23
DocScrutinizer05	meh, spare me from android shit	00:23
Sicelo	well device manager showed it in windows. no idea if it would have worked, although i guess it would have	00:24
Zungo	and the option is called allow oem unlock	00:24
DocScrutinizer05	my evaluation device refused adb, until I reset-factory	00:24
Zungo	sicelo it worked probably worked	00:24
DocScrutinizer05	some dunnowhich rogue-fuckapp messed it up	00:24
Zungo	DocScrutinizer05: something happened or the usb development setting got disabled	00:24
Zungo	usb development is not enabled by default	00:25
Sicelo	and people still say android is linux ... :-/	00:25
Zungo	also adbd is not always running	00:25
DocScrutinizer05	no, been enabled. I checked everything 5 times with experts doublechecking	00:25
Zungo	and re-enabling it?	00:25
Zungo	rooted?	00:25
DocScrutinizer05	believe me, it been fucked up	00:25
Zungo	well certainly that's a odd issue	00:26
DocScrutinizer05	this shit device is absolutely un-rootable (so far)	00:26
Sicelo	what device was it DocScrutinizer05?	00:26
DocScrutinizer05	Cat S60	00:26

Sicelo	Zungo: i will try someone tomorrow who's got a Windows computer. if not, i'll have to get one of the admins at work on monday to let me install :p	00:28
Zungo	sicelo: it's not installable, you need admin privileges to do the flashing	00:28
Sicelo	yes, that	00:28
Zungo	it's not a program you install	00:28
Zungo	ah ok	00:28
Zungo	so get all the files ready	00:29
Sicelo	yes i have everything (as far as i understand) ..	00:29
Sicelo	i have twrp, and the ROM i want to install.	00:29
Sicelo	GearCM 13 seems to be the best thing out there for the Exynos S4. you can let me know if there's better	00:30
Zungo	once you flash recovery you're done with odin, make sure to delete /system/etc/install-recovery.sh	00:30
Zungo	Interesting	00:30
Zungo	i should check that out	00:30
Zungo	or maybe not, i left the phone stock and i gave it away	00:31
Zungo	its still around but now i have a nexus 5x	00:31
Sicelo	Zungo: don't i need it to also flash the ROM?	00:31
Sicelo	(odin)	00:31
Zungo	odin only does tar files	00:32
Zungo	tar files containing .imgs with the partition names	00:32
Zungo	for zips you use recovery	00:32
Sicelo	so wait - the TWRP i have is .img :-/	00:32
Sicelo	should i tar it up?	00:33
Zungo	rename it recovery.img and tar it	00:33
Zungo	that should work	00:33
Zungo	isnt there a tar version on the website?	00:33
*** buZz has quit IRC		00:33
*** buZz has joined #maemo		00:33
Zungo	the samsung tars are a bit odd, 7-zip reports wrong eol	00:33
Zungo	bad eol*	00:34
Zungo	unexpected eol**	00:34
Sicelo	https://www.androidfilehost.com/?fid=673368273298920000	00:34
Sicelo	um .. wrong link	00:34
Sicelo	https://dl.twrp.me/i9500/twrp-2.8.7.0-i9500.img.html	00:34
Sicelo	no tar there	00:34
Zungo	go up a directory	00:35
*** buZz has quit IRC		00:35
Zungo	sicelo, there is	00:36
*** buZz has joined #maemo		00:36
Zungo	https://dl.twrp.me/i9500/	00:36
Sicelo	ok i see it.	00:36
Zungo	they DO make tar versions of the recovery	00:36
Zungo	ok	00:36
Sicelo	thanks	00:36
*** buZz has quit IRC		00:36
*** buZz has joined #maemo		00:36
Sicelo	so i flash this with odin	00:37
Sicelo	next? i presume i flash my rom .. which i guess can be done in TWRP? rom file has to be on SD? file format?	00:37
Sicelo	the rom i downloaded came as a zip file, https://www.androidfilehost.com/?fid=601300970940399905, which comes from https://forum.xda-developers.com/galaxy-s4/i9500-orig-develop/gearcm-optimized-cyanogenmod-12-1-t3283820	00:39
Zungo	you cant boot back to touchwiz until /system/etc/install-recovery.sh is deleted or the rom is flashed	00:40
Zungo	gearcm is cm12.1, mind	00:40
Zungo	not 13	00:40
Sicelo	am i able to delete that from twrp? or something else is needed?	00:40
Zungo	yes, in fact twrp should tell you about it when exiting it	00:41
Zungo	oh	00:41
Zungo	you also need google drivers on windows for using adb in twrp	00:41
Zungo	just in case	00:41
Zungo	well not sure about twrp but that was the case with CM	00:41
Sicelo	i for sure hope it will still at least let me use adb on linux lol. otherwise ..	00:41
Sicelo	looks like the later version of gearcm is cm13 .. unless i didn't understand something	00:42
DocScrutinizer05	Sicelo: aiui all you need on linux is adb and fastboot	01:02
DocScrutinizer05	both are pretty basic and should work flalessly whe run as root	01:03
Sicelo	Zungo: recommendations for what i should replace touchwiz with?	01:10
Zungo	hmm	01:11
Zungo	i am not sure	01:11
Zungo	cm should be great choice for a pure android experience, sicelo	01:11
Sicelo	cool	01:11

ovaltine_	hi all	14:11
ovaltine_	i have a old n900, i wanted to know what repositories are people using these days	14:11
ovaltine_	i was thinking since its been years that I have updated it, there must be some repos outdated or closed and maybe there r new ones that the community setup	14:12
ovaltine_	so let me know thanks	14:12
KotCzarny	cssu most notably	14:12
KotCzarny	if you missed that	14:12
ovaltine_	yes i missed	14:12
KotCzarny	ćssu	14:12
KotCzarny	~cssu	14:12
infobot	from memory, cssu is http://wiki.maemo.org/Community_SSU, or (Community Seamless Software Update)	14:12
ovaltine_	also i am not using the cssu rom, i have the last nokia rom that they released that had some security bug fixed, dont know maybe it was related to ssl or what, many years back	14:13
*** cyteen has quit IRC		14:13
KotCzarny	you definitely want cssu then	14:15
KotCzarny	as cssu is not a rom, but kind of security.debian.org repos	14:15
ovaltine_	btw	14:20
ovaltine_	who is paying for tmo to keep it hosted and all?	14:20
KotCzarny	maemo foundation	14:20
ovaltine_	is it all community members?	14:20
KotCzarny	yup	14:20
ovaltine_	ok	14:20
ovaltine_	cool	14:20
*** Kabouik has joined #maemo		14:23
*** cyteen has joined #maemo		14:25
bencoh	you still need mirrors for the old nokia repositories though	14:29
bencoh	(since a few things still depend on those)	14:29
KotCzarny	bencoh, its explained in article	14:29
bencoh	oh? neat	14:30

KotCzarny	miasma: point is, they could've done better for the same price, ie. better usb-sata chip and use box as a big radiator	15:39
KotCzarny	eh. echan.	15:39
*** florian has quit IRC		16:44
Enrico_Menotti	Is there a way to get a verbose output from NOLO?	16:44
KotCzarny	yes, use debug uart	16:45
Enrico_Menotti	So I need some hardware...	16:46
KotCzarny	quick tip: it's not that easy to get proper hw	16:46
Enrico_Menotti	In fact, I was wondering whether there was some log file with NOLO's output.	16:47
KotCzarny	have some fun: https://wiki.maemo.org/Category:N900_Hardware	16:48
KotCzarny	https://wiki.maemo.org/N900_Hardware_Hacking/serial_dump	16:49
Enrico_Menotti	Ok, so basically I think I can't do that (at least for the moment).	16:50
KotCzarny	yup	16:51
Enrico_Menotti	So let me tell you what I am doing (as usual, I'm experimenting). I'm trying to boot a standard Linux distribution. It's just a test. I have found that mainline kernel has some capabilities for the N900. I tried with the OMAP2plus conif file, and built the kernel. Now I'd try to upload it by Nokia's flasher (upload, not flash). I have been able to do that with Rescue OS's kernel. But no sign of life (with standard	16:53
Enrico_Menotti	Linux).	16:53
Enrico_Menotti	*config file	16:54
Enrico_Menotti	So I was thinking about NOLO's log to understand whether something was happening or not.	16:54
KotCzarny	see instructions on http://elinux.org/N900	16:54
KotCzarny	if you missed something	16:55
Enrico_Menotti	I have read that page. Let me check again.	16:55
KotCzarny	see u-boot paragraph	16:56
Enrico_Menotti	Ok, it'd like to avoid using u-boot for the moment. I already installed it and in the end bricked the device (not caused by u-boot), and it's been a hard task to unbrick it.	16:58
*** Venemo has joined #maemo		16:58
Enrico_Menotti	I'd like to use the flasher-3.5 as it is outlined in the instructions for Rescue OS.	16:58
Enrico_Menotti	(To upload and boot.)	16:59
Enrico_Menotti	Probably I'm missing the modules. But I'd like to understand whether the kernel is booting at all.	17:04
DocScrutinizer05	~tell ovaltine_ about lazyflashing	17:31
DocScrutinizer05	~tell ovaltine_ about BM	17:32
DocScrutinizer05	~tell ovaltine_ about jrrepos	17:32
DocScrutinizer05	~tell ovaltine_ about jrtools	17:32
KotCzarny	he doesnt want flashing, he wants to experiment	17:32
DocScrutinizer05	Enrico_Menotti: ((it's been a hard task to unbrick it)) WHAT?	17:36
*** auenf has joined #maemo		17:38
Enrico_Menotti	Well, I was unable to reflash it after having installed u-boot. I don't give the cause to u-boot - I had messed up some file in Maemo's file system. But in any case, the flasher wasn't recognising the N900 at the usb port.	17:38
DocScrutinizer05	in a chain x-y-z you played with y and nuked it and you found it a hard task to regain it using x (which it is evidently not), so you prefer to play with x now (NOLO) which you don't even know the mystery (coldflashing) you need to use for fixing it?	17:39
*** auenfx4 has quit IRC		17:39
Enrico_Menotti	Cold flashing was not working anymore.	17:40
DocScrutinizer05	bullshit	17:40
Enrico_Menotti	Now it's ok - this happened a few weeks ago.	17:40
DocScrutinizer05	coldflashing was not needed in your case	17:40
Enrico_Menotti	It was my first trials with this device - I did not know what I was risking.	17:41
DocScrutinizer05	and coldflashing is only brickable with a sledge hammer, it's in ROMBOOT	17:41
Enrico_Menotti	Ok, maybe cold flashing was working, but I could not flash the device with the usual chain eMMC image - FIASCO image.	17:42
DocScrutinizer05	you did it wrong	17:42
DocScrutinizer05	~flashing	17:42
infobot	hmm... maemo-flashing is http://wiki.maemo.org/Updating_the_tablet_firmware, or - on linux PC - download&extract http://maemo.cloud-7.de/maemo5/patches_n_tools/maemo-my-private-workdir.tgz, cd into it, do sudo ./flash-it-all.sh; or see ~flashing-cmdline, or see ~lazyflashing	17:42
DocScrutinizer05	has it ALL, since ages	17:43
Enrico_Menotti	Maybe, but in the end, if I remember the details, I had to flash just the kernel.	17:43
DocScrutinizer05	well, good luck.	17:43
Enrico_Menotti	In any case, now that's not so relevant anymore, since it's an issue solved. A couple of days ago I also reflashed the whole thing with stock eMMC and FIASCO image, and it's working properly. I followed the instructions on the page you linked right now.	17:44
Enrico_Menotti	(Including removing the battery in-between the two flashes.)	17:45
DocScrutinizer05	it seems you're one of those curious users that are determined to do learning by try&error, not bothering about verifying the assumptions your experiments are based on	17:45
DocScrutinizer05	for booting a kernel you need to provide a few environment items, often kernel commandline. make sure you understand how or even if at all you could adjust this in NOLO to match what your kernel needs	17:47
Enrico_Menotti	Well, the problem is not that I don't want to verify my assumptions. The problem is that I found a bit difficult to find a comprehensive documentation about what I was trying to do. Let me explain: at the beginning, I did not know about Maemo.org, neither about this channel on IRC. I just tried. Now I'm step by step checking what I do.	17:48
DocScrutinizer05	hint: on OMAP3 kernel it seems it's ATAGS not kernel cmdline	17:48
DocScrutinizer05	let me help you out a little bit maybe	17:49
Enrico_Menotti	Ok.	17:49
DocScrutinizer05	the absolute basics: http://www.omappedia.org/wiki/Bootloader_Project	17:49
DocScrutinizer05	on N900 Nokia called their version of uBoot "NOLO"	17:50
Enrico_Menotti	Ah, did not know it's a version of uBoot. I know NOLO is a bootloader, but I thought it was just developed by Nokia.	17:51
DocScrutinizer05	the maemo implementation of uBoot by pali is a combined uBoot+kernel in one "package" that gets loaded by NOLO as if it was a kernel but executes a 2nd layer uBoot that can do all the awesome things a uBoot is meant to be able to do	17:51
DocScrutinizer05	~uboot	17:53
infobot	N900 uBoot is a siamese twin binary [uBoot+stockMaemoKernel] that resides in kernel NAND partition /dev/mtd3 aka "kernel". You can't uninstall it, rather you'll nuke it when you flash/install another kernel like stock maemo kernel or powerkernel. To start other than stock maemo kernel via uBoot, you have to provide the according kernel image files, or http://talk.maemo.org/showthread.php?t=81613	17:53
Enrico_Menotti	Ok, I already read something about this.	17:53
*** vahe has joined #maemo		17:54
Enrico_Menotti	Now for the moment I'd avoid flashing again u-Boot. I'd just want to understand how to put standard Linux kernel in a format suitable to be uploaded (not flashed) and booted by the flasher-3.5.	17:54
DocScrutinizer05	maemo by default has kernel in "an own partition" (on NAND). Pali's maemo-uBoot either loads the stock kernel other siamese half it comes with, or you load kernel.bzimage whatever the name, which can live in maemo rootfs or on eMMC or uSD in a file	17:56
DocScrutinizer05	to boot a kernel from NOLO you need special kernel patches aiui, to fix the atags/cmdline thing	17:57
DocScrutinizer05	https://www.ixquick.com/do/search?q=uboot+atags	17:58
Pali	uboot cannot load kernel image from maemo rootfs (nand, ubifs) due to huge size of code needed for red-black tree implementation	17:58
*** Venemo has quit IRC		17:58
Pali	so nand+ubifs is disabled for n900 uboot... as there is no more place in nand for it	17:58
Pali	and no special kernel patches are needed to boot directy from nolo	17:59
DocScrutinizer05	hah, now we have an expert here! \o/ thanks Pali :-)	17:59
Enrico_Menotti	Pali As it is done in Rescue OS documentation, right? flasher-3.5 -b"<arguments>"	18:00
DocScrutinizer05	>>put standard Linux kernel in a format suitable to be uploaded (not flashed)<< alternative kernels are not flashed, they are files in a filesystem and uBoot loads them like on your x86 arch pc	18:06
DocScrutinizer05	so if your concern is about avoiding the flashing of kernels, you don't need to use the rather intricate RAM load from flasher	18:08
DocScrutinizer05	see http://www.omappedia.org/wiki/Bootloader_Project, Pali's uBoot(+stock kernel) replaces the 'Kernel' in that scheme, allowing you to either boot the attached stock kernel OR boot alternative kernels and thus OS from kernel image files you provide on e.g. uSD	18:11
DocScrutinizer05	uBoot is tested and works, no issues with that	18:11
DocScrutinizer05	using RAMloaded initrd based alternative kernel is needlessly complicated and not worth anything regarding safety of the procedure	18:13
bencoh	(that would actually depends on the system you're trying to boot ... in some cases you need some initrd for rootfs to become available)	18:14
DocScrutinizer05	well, we are talking about N900. Or what's meant by "system"?	18:15
bencoh	n900 with rootfs sitting on a dmcrypt device would require cryptsetup at boot, for instance	18:16
DocScrutinizer05	also note that initrd is a parameter to kernel telling kernel what to load and execute, it's one step later than loading kernel	18:16
DocScrutinizer05	we're talking about loading kernel right now, so initrd or not is not even a issue at that stage	18:17
Enrico_Menotti	DocScrutinizer05 Right. I could flash u-boot and use that as a loader. But for the moment I'd like to try directly from NOLO. Maybe that's not possible. However, it is done with Rescue OS. I'd like to understand how.	18:19
DocScrutinizer05	>>I'd just want to understand how to put standard Linux kernel in a format suitable to be uploaded (not flashed) and booted by the flasher-3.5<<	18:19
DocScrutinizer05	that's documented in rescueOS, why don't you check that and learn how it works?	18:21
DocScrutinizer05	I don't understand what's the use to learn about RAMloaded kernel before you got your kernel booting 'in a normal way', but... that's pretty much up to you	18:22
Enrico_Menotti	Well, there is something about the initrd, as it has been pointed out to me by NIN101, but I did not find the procedure for the kernel. Apart from the flasher-3.5 -b"<parameters>". Maybe I did not check well enough.	18:23

DocScrutinizer05	anyway >>I tried with the OMAP2plus conif file, and built the kernel. Now I'd try to upload it by Nokia's flasher (upload, not flash)<< sounds like a pretty poor approach to me, mixing two unrelated problems A and B (aka ramload and new kernel) that both have many possible issues causing the whole thing to fail. A good approach is to first try make one part work (your new kernel loaded via uBoot), and only after that's accomplished try to	18:29
DocScrutinizer05	accomplish the other part, maybe even with a known good unrelated part (try ramloading a kernel that is known to work)	18:29
Enrico_Menotti	Rescue OS kernel works, e.g. (RAMloaded). Yes, I should check the new kernel by another procedure, but that would require to flash u-boot, and I'd like to avoid that for now.	18:32
DocScrutinizer05	WHY???	18:34
bencoh	why not, I'd say? booting a new kernel directly from flasher does seem simpler, and should just work, I'd say	18:36
Enrico_Menotti	Just because I'd like not to flash anything on the device for now. As I said, I had to struggle quite a lot for reflashing it.	18:36
bencoh	and it requires one less step (updating kernel in emmc/microsd)	18:36
Enrico_Menotti	bencoh Yes, this is my opinion.	18:36
bencoh	Enrico_Menotti: you should still flash uboot nonetheless, btw ... even if you don't need it for what you're trying to achieve right now	18:37
DocScrutinizer05	Enrico_Menotti: this proves you lack the knowledge to handle simple scenarios, so you try to avoid the problems in simple scenarios by opting for a complex scenario. doesn't make sense. There is no problem at all in installing uBoot	18:37
bencoh	DocScrutinizer05: I don't see how running flasher should be a complex scenario	18:38
Enrico_Menotti	Yes, that's my point as well.	18:38
bencoh	I mean, we have two working implementations of it	18:39
bencoh	they're both well tested	18:39
bencoh	and require no device modification	18:39
DocScrutinizer05	oh yeah, ramloading a system seems sooo simple. It just doesn't work with my leete new stuff so PLZ HELP!	18:39
bencoh	...	18:39
Enrico_Menotti	Ok, the fact I don't know how to do it doesn't mean it is not simple, in my opinion. It's a lack of knowledge from my side, not a higher complexity of the problem. This is my humble opinion.	18:41
DocScrutinizer05	and what makes you think your lack of knowledge would be a minor obstacle when it comes to a very süpecial procedure that's rarely ever used and thus not widely tested and only few experts and documents available to help you out?	18:45
Enrico_Menotti	Yes, this is true as well. If I can't find out how to do it this way, I'll do the other way. But first I'd try to understand how this way works. (And it works at least for one system, Rescue OS.)	18:47
DocScrutinizer05	you want to avoid problems form lack of knowledge how to fix a fsckd up uBoot config (which is a very well known issue easily fixed and you can find a dozen answers to any question you have with it), and you decide the best way is to use a method that basically only Pali, nin101 and fmg have used on a regular basis	18:48
bencoh	DocScrutinizer05: and pretty much everyone that has been using rescueOS (?)	18:49
DocScrutinizer05	no, those USED it but don't necessarily understand shit of how it works	18:49
DocScrutinizer05	let me just point out that it's based on NOLO which in turn isn't FOSS like uBoot	18:51
DocScrutinizer05	NOLO and flasher	18:51
DocScrutinizer05	don't know if Pali inverstigated it and implemented it into 0xffff	18:51
Enrico_Menotti	Well, if they may help me, I hope Pali and NIN101 will do. Don't want to disturb too much, however.	18:52
bencoh	he did (implement kernel loading in 0xffff)	18:53
DocScrutinizer05	nin101 already helped you,pointing you to his stuff how rescueOS works and how to prepare the image to load	18:53
DocScrutinizer05	[2017-03-30 Thu 14:13:06] <NIN101> https://github.com/NIN101/N900_RescueOS/blob/master/howtocreate https://github.com/NIN101/N900_RescueOS/blob/master/HACKING	18:55
Enrico_Menotti	Yes, I read it many times. I will google for "buildroot" and see what comes out.	18:57
DocScrutinizer05	>><Enrico_Menotti> So let me tell you what I am doing (as usual, I'm experimenting). I'm trying to boot a standard Linux distribution<< WONT WORK with intird!!! NOT ENOUGH RAM!	18:58
DocScrutinizer05	you're aware why it's called initRamDisk? because it takes away RAM from system to store files in it that are usually stored on e.g. BABD or eMMC or uSD	19:00
DocScrutinizer05	NAND, not babd	19:00
DocScrutinizer05	and btw no normal user would refer to installation of uBoot as "flashing", it's a normal package install from user perspective	19:02
DocScrutinizer05	this is not android where you need to flash custom ROM	19:02
Enrico_Menotti	This is how I came to yesterday's problem of how to transfer files from my computer to the N900. I put the file system on the sd card. But what for the kernel? Without u-boot I cannot upload it from eMMC or sd card. I need to upload it to RAM by the flasher and boot it, right?	19:04
DocScrutinizer05	the eror lies in "without uboot"	19:05
DocScrutinizer05	not even trying to explain how you will run into further special customization need when trying to make your initrd pivotroot onto the system on uSD then. Or musing about if or if not flasher+NOLO can load kernel from uSD file instead uploading i	19:09
DocScrutinizer05	honestly what's so unbearably terrible about `apt-get install uboot-pr13` ?	19:11
Enrico_Menotti	As I said, if I can't avoid it, I will do it.	19:12
DocScrutinizer05	and yes, to get rid of it in case you messed up completely (hard to imagine how you'd do that) you simply flash stock kernel and everything back to normal, which is a nobrainer just like the installation	19:12
DocScrutinizer05	Pali: when uboot missing its config files, would it break or simply boot straight into default aka stock kernel?	19:14
Pali	uboot has hardcoded in its binary some defaults	19:15
DocScrutinizer05	ta! :-)	19:15
Pali	which are used when boomenu.src file is not available	19:15
Pali	so yes, it boots default attached kernel	19:15
DocScrutinizer05	Enrico_Menotti: see, it's basically impossible to break uboot	19:16
Enrico_Menotti	...	19:16
Pali	correct package is u-boot-flasher: http://maemo.org/packages/view/u-boot-flasher	19:16
Enrico_Menotti	The first time, I flashed everything ok, installed u-boot, messed up, and then I was unable to boot stock kernel. Nor normally flash the device. I also ended up with empty battery. Pali and NIN101 helped me in order to boot rescue OS from the sd card. This allowed charging the battery. Then I had to flash just the kernel, if I remember it right, and then I was able to flash normally.	19:19
freemangordon	Enrico_Menotti: anyway, you can;t boot omap2plus_defconfig build kernel iirc	19:19
freemangordon	check the one on Pali's tree on github	19:20
freemangordon	~elinux	19:20
infobot	[elinux] http://eLinux.org/ or the Embedded Linux project. cross compilers. build systems, hardware hacking etc.	19:20
freemangordon	Enrico_Menotti: https://github.com/pali/linux-n900	19:20
DocScrutinizer05	>>The first time, I flashed everything ok, installed u-boot,<< ok, so far >>messed up<< whatever you did, it been most likely because of lack of experience and info >>and then I was unable to boot stock kernel<< well, quite possible if you installed another kernel the wrong way >>Nor normally flash the device.<< PEBCAK	19:21
Enrico_Menotti	freemangordon This is something in fact I would like to understand. Maybe I did the wrong thing in choosing mainline kernel. But there is a branch dedicated to the N900. And it's incorporated into the mainline. I tried to make that config file and then make menuconfig. Seems there are options for the N900.	19:22
DocScrutinizer05	>>I also ended up with empty battery<< which is clearly PEBCAK since you been warned a dozen times at least during your study of docs and howtos that you need a fully charged battery before you mess around with the system in any way. And you shouldn't let system run in a bootloop for hours	19:23
bencoh	DocScrutinizer05: I honestly don't think this is helping	19:24
DocScrutinizer05	It helps correct user attitude that dispises uBoot based on unrelated bad experience	19:25
Enrico_Menotti	DocScrutinizer05 What's that acronym PEBCAK? Sorry, I'm a poor Italian. :)	19:26

DocScrutinizer05	PEBKAC is just a short term for "user did probably something wrong, maybe because of lack of good instructions or documentation, maybe because of a typo or whatever other oopsie that everybody does from time to time"	19:38
bencoh	(silly me)	19:38

Enrico_Menotti	freemangordon Ok, thank you, got it. Just in order to avoid doing strange things, I'd have a second question. The system image - I can't upload it to RAM (2GB). So should I mount it on a Linux system and then extract the contents to the SD card?	20:18
Zungo	cant you use dd ?	20:20
Zungo	also the image might be writeable?	20:20
bencoh	uimage -> zimage is a simple dd skip=64 bs=1	20:20
DocScrutinizer05	:-D \o/	20:21
Enrico_Menotti	Zungo Ok, let me try.	20:21
bencoh	and building zimage (vmlinuz) from a kernel tree is quite simple considering you've succeeded in building uimage :)	20:21
DocScrutinizer05	easy to verify with mkimage applied to the result and check if it creates the original uimage	20:22
bencoh	DocScrutinizer05: you'd need to know mkimage parameters	20:22

*** xy2_ has quit IRC		20:28
*** xy2_ has joined #maemo		20:29
freemangordon	Enrico_Menotti: on ubuntu you can write compressed image directly to SD card with "disks" UI. No idea about debian, but there should be similar functionality	20:32
freemangordon	Enrico_Menotti: but simple "extract" won't do the job, there is more than just a files	20:34
Enrico_Menotti	freemangordon Thanks. I used rsync for transferring the Debian file system to the sd card. I was thinking about the same way here. Clearly, it is easier to write directly the zImage. Now, I have (as usual :) ) a quite convoluted situation. Let me explain.	20:36
Enrico_Menotti	My main computer is a Mac. I have a Debian live distribution running on another computer, which is unable to read sd cards (doesn't have a slot for that). I'd use directly the N900 for writing the disk image to the sd card.	20:37
freemangordon	Enrico_Menotti: I am not sure rsync will do the job, but I might be wrong. just to be sure, use dd	20:37
Enrico_Menotti	So now I'd resort to dd. But I think the zImage expects the sd card to be the right size, or a partition to be prepared in advance, am I right or wrong?	20:38
freemangordon	doing dd of uncompressed image to sdcard is all you need, this is why it is disk image, but not a file archive	20:39
freemangordon	*files archive	20:39
Zungo	you can always use CLI	20:40
Zungo	and theres GParted	20:40
Enrico_Menotti	Zungo On N900?	20:40
Zungo	idk	20:41
Zungo	i do not have a n900	20:41

freemangordon	Enrico_Menotti: no, on debian	20:41
Sicelo	Zungo: you'll be very happy when you finally get it :)	20:42
freemangordon	install gparted and use it to restore the image onto the sdcard	20:42
Enrico_Menotti	Don't have the GUI on Debian. Just command line (small computer).	20:42
Zungo	debian is like ubuntu :p	20:42
freemangordon	ah	20:42
Zungo	you can always install X	20:42
freemangordon	well, dd is your friend	20:42

freemangordon	mhm	20:42
freemangordon	but I like it, in most of its part	20:43
buZz	yeah, i like devuan aswell	20:43
Zungo	actually gparted doesnt restore images but can attempt to restore lost partitions	20:43
Zungo	photorec or testdisk for that	20:44
freemangordon	Enrico_Menotti: BUT - don;t forget to uncompress the image first (well, you can uncompress it on-the-fly)	20:44
Zungo	they're a bit old through	20:44
Enrico_Menotti	freemangordon Ok, I'm still so handicapped with Linux & friends that I have to google for the right commands. But I'll manage to find the way. Just a question about dd: I found it is usually invoked with an option "bs=4096". Is this choice standard?	20:45
freemangordon	I think yes	20:46
freemangordon	but I am not exactly dd guru, so don't quote me on that one :)	20:47
Enrico_Menotti	Ok, I'll just try.	20:47
Zungo	check the man pages for that	20:47
freemangordon	but it should be something like dd if=$image of=/dev/$sdcard bs=4096	20:47
Zungo	you'd have to figure out with what default commandline is dd compiled with	20:48
Sicelo	what image is he restoring by the way? sorry i missed the first part of discussion	20:48
freemangordon	Zungo: what is the shell tool to uncompress .xz images?	20:48
freemangordon	Sicelo: devuan n900	20:48
Zungo	because most of the time the defaults are fine with dd	20:48
Sicelo	ok	20:48
Sicelo	xz decompresses .xz :)	20:49
Zungo	lel	20:49
freemangordon	thancs	20:49
freemangordon	*thanks	20:49
freemangordon	Sicelo: it doesn;t need parameters to decompress it and to put it on stdout?	20:49
Sicelo	i'm happy Enrico_Menotti is installing a proper linux now (not Nitdroid)	20:50
Sicelo	where' the link for devuan n900?	20:50
Sicelo	well, a quick check says for stdout, you use -c	20:50
freemangordon	Enrico_Menotti: some notes - devuan image is without X, login is usr=root pwd=toor, IIRC	20:51
Sicelo	link please :)	20:51
freemangordon	Enrico_Menotti: so, you may try with "xz -c $image.xz \| dd -of=/dev/$sdcard bs=4096", without quotes	20:52
freemangordon	Sicelo: link to what?	20:52
Sicelo	devuan image	20:52

freemangordon	Zungo: no, embedding maemo with devuan is WIP	21:04
freemangordon	Zungo: see https://github.com/fremantle-gtk2	21:05
Zungo	right	21:06
Zungo	has those updated yet?	21:06
freemangordon	buZz: Zungo: see videos at http://46.249.74.23/allwinner/ for some very very early results. This is gtk3 hildon-desktop running on top of devuan n900 image prepared with parazyd's armsdk.	21:07
freemangordon	Zungo: updated?	21:07
buZz	allwinner n900? YES PLEASE	21:07
buZz	:)	21:08
parazyd	^_^	21:08
freemangordon	no, it is not allwinner n900, but some cheapo alwinner tablet I bought for the purpose of POC	21:08
Zungo	hoping the ia32 variants are ready soon	21:08
Zungo	lel	21:08
freemangordon	Zungo: well, actually I am using x86-64 VM for all the development ;)	21:09
freemangordon	and testing	21:09
freemangordon	Zungo: so, in theory, all you need to do is to git clone;dpng-buildpackge	21:09
buZz	freemangordon: A13 ? :D	21:09
freemangordon	*dpkg-buildpackge	21:10
buZz	i have some 7" A13 tablet somewhere	21:10
freemangordon	buZz: A33	21:10
Zungo	freemangordon: its juest	21:10
freemangordon	Zungo: sorry, can;t parse	21:10
Zungo	that i am juest	21:10
Zungo	-_-	21:10
freemangordon	ah	21:11
freemangordon	buZz: you need upstream kernel support AND working 3D accell	21:11
buZz	A10/13/20 afaik all have upstream & 3d accell sorta working	21:12
freemangordon	well, maybe upstream is not a must, but I don;t know how well devuan will play with some OEM kernel	21:12
buZz	with blobbed drivers though	21:12
freemangordon	buZz: yeah, blobbed	21:12
freemangordon	but a10/a13/a20 are nowhere to be found	21:13
buZz	which nowhere are you refering to?	21:13
freemangordon	ebay	21:13
buZz	oh no clue	21:13
buZz	A13 = whats inside R8	21:14
buZz	so 'CHIP' is A13	21:14
freemangordon	no idea	21:14
buZz	i'm telling you :)	21:14
freemangordon	however, having it working on A33 is better	21:14
buZz	yeah?	21:14
freemangordon	yeah, those are some 50 euros - 4 cores/512MB	21:15
buZz	i'm aware what the SOC is :P	21:16
freemangordon	ok	21:16
freemangordon	but I was not aware if you are :p	21:16
buZz	thats ok <3	21:17
buZz	appreciated	21:17
freemangordon	anyway, with help of Wizzup and parazyd, we may have maemo rebased on devuan repo on devuan servers. ofc not full maemo, but at least hildon-desktop, hildon-status-menu and hildon-home	21:18
freemangordon	in 2-3 weeks from now, if they manage to find the needed time to do it	21:19
buZz	quite nice	21:19
freemangordon	mhm. I hope to attract more devs once there is something to be shown besides a POC	21:19
Zungo	\o/	21:20
parazyd	yes i hope to do amprolla this month	21:20
freemangordon	yeah, there are piles of porting work waiting to be done, not a one-man-show task	21:20
parazyd	also devuan RC will be released	21:20
parazyd	and then hopefully the other devuan people enable the CI	21:21
freemangordon	cool	21:21
parazyd	so for other ppl interested: this way we don't "taint" devuan repos, but have our own downstream	21:22
parazyd	which takes precedence over devuan then so one can even override a devuan package	21:22
parazyd	(automagically)	21:23
freemangordon	I wonder if we can make some more noise. After all the final goal is to have a real mobile/tablet linux, so I somehow expect a bit more enthusiasm from FOSS people.	21:23
parazyd	maybe on some conferences	21:23
freemangordon	mhm. But still, there should be something at least close to functioning to be shown there	21:24
freemangordon	however, I am one function away from finishing libhildonfm porting to gio, and IIRC that was the last missing hildon-home dependency	21:25
parazyd	<3	21:25
buZz	devuan RC?	21:25
parazyd	jessie release candidate	21:25
parazyd	yeah, it's slow... but steady i guess	21:26
freemangordon	once having those 3 (h-d, h-h and h-s-m) I guess it will get easier	21:26
freemangordon	though there remains stuff like systemui etc	21:26
parazyd	i don't like that it's moving _so_ slow though. debian already froze jessie and is getting ready for stretch	21:26
parazyd	but this is not the place to bitch about it	21:26
freemangordon	not THAT hard, but time consuming	21:26
freemangordon	IT would have been great if there was at least one more dev to work on sporting stuff that we have source code of, so me to be able to focus on REing work, but...	21:27
freemangordon	*porting	21:28
KotCzarny	fmg: a10/a20 is present in those MIDxxx cheapo tablets from few years ago, that are laying around in people's houses	21:28
parazyd	we'll see	21:28
KotCzarny	and all of them would be very easy to make supported	21:29
buZz	i think so too	21:30
buZz	i can get to trying on this A13 tablet i own once something gets testable?	21:31
KotCzarny	yup	21:31
KotCzarny	you can do it now	21:31
freemangordon	KotCzarny: I have not been able to find any online source to buy anything older than a33	21:32
KotCzarny	fmg: second hand goods? unless you are interested in only something that can be bought new?	21:32
freemangordon	buZz: it is testable ATM	21:32
freemangordon	KotCzarny: yep, I wanted for it to be new, I don;t really need HW failures to mess with OS development	21:33
*** tryagain has joined #maemo		21:33
*** florian has quit IRC		21:34
freemangordon	buZz: you only need to install debian/devuan, X, 3d drivers gcc and git	21:34
KotCzarny	i have a quite successful theory, that if you buy something used that is working, it wont fail for a long time. new things, straight from the factory, otoh, can have a high chance of failure	21:35
freemangordon	could be	21:35
freemangordon	but still, it was way easier to buy it from BG merchant, with warranty and 3 days for delivery :)	21:35
KotCzarny	and if it fails, 2-3 weeks of being without device? ;)	21:36
freemangordon	and with return policy covered by EU rules	21:36
freemangordon	for that price, I can buy 2 per week :)	21:36
KotCzarny	;)	21:36
KotCzarny	yeah, that's winning argument	21:37
KotCzarny	BUT, if you manage to find a10/a13 for 5usd .. ;)	21:37
freemangordon	the key being "if you manage"	21:37
freemangordon	I failed	21:37
freemangordon	there were only 2 or 3 on some Russian sites, I'd rather not mess with	21:38
freemangordon	no EU to cover my ass there	21:38
KotCzarny	most people who own those old devices are usually not knowing what they have	21:38
freemangordon	Wizzup searched for used a10/a13 for a week or so, he found almost nothing	21:39
freemangordon	and, I think it is better to try the newest as it is probable to be supported/available for some time	21:39
freemangordon	not that a33 is the newest, but still	21:40
KotCzarny	erm, that's not true in arm land	21:40
KotCzarny	newest arent supported for 3-12 months	21:40
freemangordon	KotCzarny: what is the point to port maemo to HW you can;t buy?	21:40
KotCzarny	and vendor bsp is usually crap	21:40
KotCzarny	fmg, afair, requirement is 'mainline kernel with not locked bootloader and 3g accel'	21:41
KotCzarny	*3d	21:41
freemangordon	well, yeah	21:42
Enrico_Menotti	Sorry, I have a small issue. I have been able to use dd to write the disk image to sd card, but when I try to mount the sd card itself I get "invalid argument".	21:43
KotCzarny	dd image?	21:44
freemangordon	youcan;t mount it, as there are several partitions	21:44
KotCzarny	what dd image	21:44
freemangordon	devuan n900	21:44
KotCzarny	ahm	21:44
parazyd	be sure to uncompress it first	21:45
freemangordon	yeah, warned him several times already :)	21:45
parazyd	just making sure... why can't it be mounted then?	21:45
KotCzarny	because you need -o param	21:45
parazyd	i get mmcblk0p1 and p2 on my laptop after dd-ing	21:45
KotCzarny	if you dont specify partition	21:45
KotCzarny	parazyd, you need hdparm -z too	21:45
freemangordon	KotCzarny: hmm?	21:46
KotCzarny	or other way to reread partition table	21:46
freemangordon	ah, yeah	21:46
parazyd	partprobe, yes	21:46
freemangordon	Enrico_Menotti: just reconnect sdcard	21:46
Enrico_Menotti	I decompressed the .xz file on the Mac. Got a .img file. Transferred that to the N900. dd the image to the sd card. Under /dev I see mmcblk1 and mmcblk1p1.	21:47
freemangordon	that's the easiest way to force debian to reread the partition table	21:47
KotCzarny	reinsert card	21:47
KotCzarny	and check for new partitions	21:47
freemangordon	Enrico_Menotti: emove the back cover and then put it back	21:47
Enrico_Menotti	No other way than opening the back cover and extracting/reinserting the card?	21:47
freemangordon	just remoive tha back cover	21:47
KotCzarny	or use hdparm -z /dev/mmcblk0 (or 1)	21:47
freemangordon	no need to remove/instert the card	21:48
freemangordon	damn typos :(	21:48
Enrico_Menotti	KotCzarny Ok, will try this way.	21:48
Enrico_Menotti	No, hdparm not found on the N900. I will manage with the cover.	21:49
Enrico_Menotti	Ok, I have two partitions. The first may be mounted, but there's just a uImage inside, and the second cannot be mounted: "invalid argument".	21:54
KotCzarny	maybe its ext4	21:54
KotCzarny	ie. unsupported by n900	21:55
KotCzarny	s/n900/maemo/	21:55
infobot	KotCzarny meant: ie. unsupported by maemo	21:55
Enrico_Menotti	Ah ok.	21:55
KotCzarny	you can always check on pc	21:55
Enrico_Menotti	No, I have problems with this: the pc where I run Debian does not have a sd card reader, and the other is a Mac, which, as far as I know, is unable to read ext fs.	21:56
parazyd	KotCzarny: it is	21:56
parazyd	p1 is fat32, p2 is ext4 (purposely)	21:57
Enrico_Menotti	parazyd So what parameter do I have to pass to the kernel? rootfs=/dev/mmcblk1p2 ?	21:57
parazyd	you can't mount it under maemo	21:57
KotCzarny	he asks how to boot it	21:58
KotCzarny	on n900	21:58
Enrico_Menotti	Yes, I will boot the Devian kernel.	21:58
parazyd	my reasoning for choosing ext4 is because of this exactly. so maemo doesn't touch it	21:58
parazyd	in uboot console type 'run sdboot'	21:58
Enrico_Menotti	No uboot. Upload by flasher.	21:58
Enrico_Menotti	I need to know the parameter to be passed to the kernel.	21:58
parazyd	i wouldn't know	21:59
Sicelo	(you might want to start giving u-boot some love - or reinforce your USB)	21:59
parazyd	try root=/dev/mmcblk1p2 i guess	21:59
*** pagurus has joined #maemo		21:59
parazyd	but indeed, get uboot ;)	21:59
Enrico_Menotti	parazyd Ok if the rootfs is in the second partition, this should work.	21:59
parazyd	yes	21:59
Enrico_Menotti	After some testing I will get u boot, of course.	22:00
parazyd	the fstab has an entry for /boot	22:00
parazyd	but it's an uimage	22:00
parazyd	i dunno what else besides uboot can use it	22:00
Sicelo	Zungo: gearcm flashed :)	22:01
Zungo	congrats	22:01
Zungo	sicelo: you wont need odin again, afaik	22:01
Sicelo	yes, i only used it once	22:01
freemangordon	parazyd: re maemo won;t touch ext4 - iirc kernel-power has ext4 support	22:02
parazyd	oh ok	22:03
*** pagurus has quit IRC		22:03
parazyd	though ext4 is still a sane choice, no?	22:03
freemangordon	Enrico_Menotti: keep in mind I am not sure zImage i provided is the correct one	22:03
KotCzarny	btrfs maybe	22:03
freemangordon	uImage is though	22:03
Wizzup	freemangordon: a friend of mine said he had an old a10 tablet, but they are very hard to source	22:03
freemangordon	KotCzarny: ^^^	22:04
KotCzarny	:)	22:04
Wizzup	20:19 < freemangordon> mhm. I hope to attract more devs once there is something to be shown besides a POC	22:04
Wizzup	this :)	22:04
*** pagurus has joined #maemo		22:04
KotCzarny	who wants my a10 tablet? (touch is dead)	22:04
Wizzup	freemangordon: let's make noise once we have something that people can dd & apt-get upgrade, so to speak	22:04
Wizzup	something that has at least h-d + xterm or so	22:04
freemangordon	yeah	22:04
freemangordon	BTW, I have xterm running in my VM	22:05
KotCzarny	allwinner has particular advantage of having sdcard at higher boot priority	22:05
parazyd	i saw firefox in your tablet vid :)	22:05
freemangordon	I use fel	22:05
freemangordon	parazyd: yeah	22:05
freemangordon	parazyd: and debian file manager (with some strange name) and wicd	22:06
parazyd	there is networkmanager btw, in jessie-proposed iirc	22:07
parazyd	deb http://auto.mirror.devuan.org/devuan jessie-proposed main	22:08
parazyd	i haven't tried it yet	22:08
freemangordon	parazyd: isn;t it too heavy for embedded?	22:10
KotCzarny	i hate networkmanager (when it doesnt work)	22:10
Enrico_Menotti	Ok, signs of life. The kernel boots, it seems, but gets panic. Unable to mount the rootfs. May it be just because it is ext4?	22:10
freemangordon	Enrico_Menotti: no, this means you've passed wrong root= parameter	22:11
parazyd	i don't know. i know it's nifty for users though. not sure how maemo does networking, but NM has vpn stuff, wifi and eth	22:11
parazyd	and it usually broke less often than wicd in my experiences	22:11
freemangordon	could be, but at least on ubuntu, the applet is FUBAR	22:12
parazyd	Enrico_Menotti: you can also pass 'rootfstype=ext4'	22:12
freemangordon	though it is canonical to be blamed here, no NM	22:12
freemangordon	parazyd: no need	22:12
freemangordon	iirc	22:12
* freemangordon checks his n900 u-boot config		22:13
parazyd	freemangordon: i'm in love with netifrc (from openrc)	22:13
parazyd	serves me pretty well	22:13
Enrico_Menotti	freemangordon root=/dev/mmcblk1p2	22:13
Enrico_Menotti	Should be right. It's the ext4 partition.	22:13
freemangordon	Enrico_Menotti: try with root=/dev/mmcblk0p2 rootwait	22:14
Enrico_Menotti	I have also a rootdelay.	22:14
freemangordon	Enrico_Menotti: sd card numbering differs in maemo compared to upstream kernel	22:15
Enrico_Menotti	Ah that's the point so.	22:15
freemangordon	mmcblk1 in maemo is mmcblk0 in upstream, iirc	22:15
parazyd	ah so it IS the n900 doing that	22:15
parazyd	i was wondering what board did it :D	22:15
freemangordon	parazyd: maemo does it	22:16
freemangordon	it is not the board or the kernel	22:16
Enrico_Menotti	freemangordon There is also the mmcblk0 under maemo, which is the eMMC. Are they switched in Devian?	22:16
parazyd	yes, that's what i meant	22:16
parazyd	wrong choice of words	22:16
freemangordon	Enrico_Menotti: yes	22:16
freemangordon	iirc	22:16
parazyd	Enrico_Menotti: *devuan, yes	22:16
Sicelo	yes they are	22:16
KotCzarny	its 'devUan'	22:17
KotCzarny	not devian(t)	22:17
freemangordon	Enrico_Menotti: if that root= does not work, try with no command line at all	22:19
freemangordon	iirc the kernel should have the correct cmdline	22:20
Enrico_Menotti	Sorry phone call.	22:20
freemangordon	Enrico_Menotti: this is from the config used to build the kernel:	22:20
Enrico_Menotti	Devuan, right, sorry.	22:20
freemangordon	CONFIG_CMDLINE="root=/dev/mmcblk0p2 rw mtdoops.mtddev=log console=tty0 console=ttyO2 omapfb_vram=7M omapfb.mode=lcd:848x480-16 nokia-modem.pm=0"	22:20
freemangordon	so, do not pass kernel command line at all	22:21
*** xy2_ has quit IRC		22:21
Enrico_Menotti	Ok, let's try.	22:22
parazyd	freemangordon: btw, if you have a sane kernel config for the n900, let me know. the current one lives here: https://github.com/dyne/arm-sdk/raw/next/boards/kernel-configs/n900.config	22:23
parazyd	but it can be improved imo	22:23
Wizzup	21:10 < freemangordon> parazyd: isn;t it too heavy for embedded?	22:25
Wizzup	I think it might not be	22:25
Wizzup	I dpn't care about the politics, but I think networkmanager may be easy to adept for the n900, but maybe not.	22:26
Wizzup	I figured we could take the nm-applet and modify it to fit our needs	22:26
Wizzup	but wicd may be fine too...	22:26
Wizzup	s/adept/change/	22:26
KotCzarny	isbt nm relying on some weird libs?	22:27
Wizzup	well, let's get h-d on there first and then figure it out	22:27
freemangordon	parazyd: well, https://github.com/dyne/arm-sdk/commit/7d9cc10223e07bf21b0370ae3fe3a043802b9b55	22:30
freemangordon	The sane n900 config I have is there	22:30
freemangordon	it it almost the same as the one from Pali's repo	22:30
parazyd	ah ok	22:31
Enrico_Menotti	freemangordon I tried a few times, reading the output from the kernel. Right, the external sd card is mmcblk0, two partitions. If I don't specify a root=, it says "unable to mount unspecified rootfs" or something of this kind. If I specify the root=/dev/mmcblk0p2, it's still complaining he can't mount it. I will try with also rootfstype=ext4.	22:31
parazyd	yeah in that one the watchdogs were modules	22:31
parazyd	now they're in the kernel	22:31
parazyd	other than that i don't remember changing anything	22:31
parazyd	but ok, eventually we'll figure out if there's things that need to be added	22:32
*** cyteen has joined #maemo		22:40
Enrico_Menotti	Ok, something more. I tried with "rootwait root=/dev/mmcblk0p2 rootfstype=ext4". This now ends with "Mount failed for sys/fs/selinux: no such file or directory".	22:41
KotCzarny	wth are you booting?	22:41
parazyd	O.o	22:42
Enrico_Menotti	KotCzarny After some discussion about how to try booting a standard Linux distribution, I am trying to boot Devuan.	22:43
Enrico_Menotti	Well, at least I know there is something wrong with the mainline kernel I built, since it does not give signs of life. This other one does... :)	22:46
KotCzarny	why dont you use devuan kernel on your sdcard?	22:46
Wizzup	Enrico_Menotti: If you want linux on your n900: 1) flash maemo, install cssu, install u-boot from maemo 2) dd the devuan image from parazyd to the sd card	22:47
Wizzup	3) profit, but you'll need to install xorg and others, and configure the touch screen	22:47
Wizzup	I have some instructions on how to do that with xinput	22:47
Wizzup	freemangordon: where should we document things, maemo wiki?	22:47
Enrico_Menotti	I am trying to upload and boot by using the flasher. To this aim, I need to upload the kernel to RAM from the computer and boot it. The file system image on the other hand is on the sd card.	22:48
Enrico_Menotti	Wizzup Yes, there has been a long discussion about how to test a new kernel. I'd try to upload it via flasher, instead of using u-boot.	22:48
Wizzup	Enrico_Menotti: why would you do that?	22:49
freemangordon	Wizzup: i guess yes, maemo wiki	22:49
Enrico_Menotti	Wizzup It's just a preliminary test. I would like to test without flashing anything.	22:50
freemangordon	Enrico_Menotti: does it complain about missing modules?	22:50
freemangordon	as it is possible that zImage I provided does not match the contents of /lib/modules	22:50
Enrico_Menotti	Don't know. The messages stay on the screen just for a while, without backlight. I am unable to read all.	22:50
freemangordon	Enrico_Menotti: try to make zImage from Umiage	22:51
freemangordon	*uImage	22:51
freemangordon	Enrico_Menotti: or, just follow the instruction on https://github.com/dyne/arm-sdk to create your own zImage and kernel	22:53
freemangordon	and devuan image	22:53
Enrico_Menotti	Ok, a minute. I think I am missing something. I downloaded zImage and the Devian .img.xz file. Unpacked the latter and used dd to write it to sd card. I upload the zImage by flasher and booted it.	22:53
parazyd	sidenote; it defaults to a uImage	22:53
parazyd	freemangordon: should i include both zImage and uImage on the /boot partition perhaps?	22:54
freemangordon	parazyd: but, there is zImage in the kernel build directory	22:54
parazyd	yes there is	22:54
freemangordon	Enrico_Menotti: what you did is correct	22:54
Enrico_Menotti	There is also the lib.tar.gz. What about it?	22:55
parazyd	that one corresponds to the zImage	22:55
parazyd	you need it	22:55
freemangordon	lemme check	22:55
Enrico_Menotti	Yes, but how to use it?	22:55
parazyd	extract it in the rootfs	22:55
freemangordon	those modules match the uImage	22:55
Enrico_Menotti	parazyd I cannot access the rootfs since it is ext4.	22:56
parazyd	oh i might have something...	22:56
freemangordon	and I think those modules should already be in the devuan image	22:56
parazyd	freemangordon: if he downloaded my latest image, that's kernel 4.10	22:56
Wizzup	Enrico_Menotti: you can install u-boot and then test whatever you want from u-boot ;)	22:57
Wizzup	freemangordon: btw, did you ever try to record anything with arecord on mainline?	22:57
freemangordon	Enrico_Menotti: which image do you use? mine or parazyd's?	22:57
Enrico_Menotti	Parazyd's.	22:57
parazyd	then you need an according zImage	22:58
freemangordon	well then, my zImage is linux 4.8, parazyd's devuan image is for linux 4.10	22:58
Enrico_Menotti	Ah ok.	22:58
parazyd	you can get it from the uImage that's on the fat32 partition (mmcblkXp1)	22:58
Enrico_Menotti	Ok, and convert it to zImage, right?	22:58
freemangordon	parazyd: care to give the command to convert uImage to zImage?	22:58
parazyd	if only...	22:59
freemangordon	Enrico_Menotti: right	22:59
parazyd	google shoudl know, i don't	22:59
freemangordon	"bencoh: uimage -> zimage is a simple dd skip=64 bs=1"	23:00
freemangordon	so it should be dd if=uImage of=zImage skip=64 bs=1	23:00
Enrico_Menotti	freemangordon Ok, thank you, I was unable to find it again.	23:00
freemangordon	no idea if it works	23:00
parazyd	i can pop a new build if needed, and give you a zImage	23:01
freemangordon	let him first try with dd, it seems easy	23:01
Enrico_Menotti	parazyd No need for now, thanks.	23:01
parazyd	ok	23:02
freemangordon	Enrico_Menotti: you may also try with my devuan image if you fail with parazyd's one	23:02
* freemangordon is afk		23:02
Enrico_Menotti	Ok. I will try.	23:02

parazyd	Enrico_Menotti: any luck?	23:10
Enrico_Menotti	A minute...	23:11
parazyd	i started a 4.10 build	23:11
parazyd	so i can give you the correct zImage in a few minutes	23:11
Enrico_Menotti	No, the same mount failed for that file.	23:12
Enrico_Menotti	"Mount failed for sys/fs/selinux: no such file or directory"	23:14
Enrico_Menotti	No, wait, I've got a login!!!	23:14
parazyd	:)	23:14
Enrico_Menotti	parazyd Could you please tell me again user and pass?	23:15
parazyd	root:toor	23:15
Enrico_Menotti	Yes, it's working. But no backlight.	23:16
parazyd	that's strange, should be on full	23:16
parazyd	maybe it's some magic that u-boot does	23:16
Enrico_Menotti	Anyway, now I'm sure my standard Linux kernel, the one I built, has something wrong.	23:18
parazyd	https://pub.parazyd.cf/tmp/zImage	23:18
parazyd	here's a zImage just built	23:18
parazyd	but i think it's the same thing as what you have now	23:18
Enrico_Menotti	Probably. Thank you anyway.	23:19
Enrico_Menotti	I will try, at any rate.	23:19
parazyd	https://github.com/dyne/arm-sdk/blob/next/boards/nokia-n900.sh#L78	23:19
parazyd	here's how the kernel is built	23:19

Enrico_Menotti	Guys, I have a problem.	23:31
*** pagurus has quit IRC		23:31
Enrico_Menotti	Seems my N900 doesn't go to update mode anymore. Maemo boots, however.	23:32
Zungo	broken update mode?	23:32
Sicelo	what's updated mode?	23:32
Enrico_Menotti	I mean flash mode... the mode you go in if you press "u" and connect the usb.	23:33
Enrico_Menotti	Also, if I just connect the usb without doing anything, it does not charge. It does if I press the power button and wait a while.	23:34
parazyd	tried taking the battery out?	23:35
Enrico_Menotti	No. I will try.	23:35
*** cyphase has joined #maemo		23:35
parazyd	that usually helps	23:35
Enrico_Menotti	In this case not, seems.	23:36
Enrico_Menotti	Ok, I will say what I did. After booting Devuan, I entered the shell, and issued "poweroff". Maybe wrong thing? Should I have pressed the power button to turn it off?	23:37
*** florian has joined #maemo		23:39
*** cyphase has quit IRC		23:41
Enrico_Menotti	Ok, I have been able to go again in flash mode. Pressing and holding "u" AND pressing and holding the power button. God knows what happened. I fear I will have to flash it again. :(	23:42
