| DocScrutinizer05 | ShadowJK: look at lsmod on N900 | 01:13 |
| DocScrutinizer05 | ShadowJK: well, maybe that doesn't help | 01:16 |
| ShadowJK | N900's tcp stack is certainly not in the modem ;p | 01:16 |
| DocScrutinizer05 | ShadowJK: actually I never looked into it myself, I just heard at least lower half of tcp/ip stack is inside modem for GPRS | 01:16 |
| DocScrutinizer05 | and then there's GPRS data stack under any TCP layer | 01:17 |
| DocScrutinizer05 | I don't think you could fake MAC of a modem | 01:18 |
| DocScrutinizer05 | I'm also quite sure there's no broadcast as we know it, and no promiscuous mode ;-P | 01:19 |
| ShadowJK | I don't know what this "lower half" is, but you can even generate the IP level stuff yourself, which I think qualifies as entire tcp/ip stack in linux | 01:19 |
| ShadowJK | Those things are ethernet things, not tcp/ip | 01:19 |
| ShadowJK | and we're not running ethernet here :P | 01:19 |
| DocScrutinizer05 | obviously | 01:19 |
| DocScrutinizer05 | actually we're running PPPoE iirc | 01:20 |
| ShadowJK | no | 01:20 |
| DocScrutinizer05 | might be true (or not) only for UMTS | 01:21 |
| ShadowJK | pnatd emulated a dialup modem though, pnatd is what you get over the bluetooth dun channel | 01:21 |
| ShadowJK | emulates* | 01:21 |
| *** lbt_away is now known as lbt | 01:21 | |
| DocScrutinizer05 | I know what pnatd is | 01:21 |
| ShadowJK | There a usb gprs/umts/hspa modems that emulate ethernet too, like n900 can do on usb | 01:22 |
| *** rm_work has quit IRC | 01:22 | |
| ShadowJK | the ethernet level stuff is just for talking with the modem though | 01:22 |
| DocScrutinizer05 | probably the easiest way to eliminate all misconceptions was to start wireshark on isi | 01:23 |
| *** lxp1 has quit IRC | 01:24 | |
| DocScrutinizer05 | iirc it shows nicely dissected data packages, and at least from them I could tell what protocol it's using on that layer | 01:24 |
| ShadowJK | I think that'd look like ip inside isi inside phonet | 01:25 |
| *** muelli has joined #maemo | 01:25 | |
| DocScrutinizer05 | for all I know GPRS has an own connection management plus ACK/NACK | 01:25 |
| ShadowJK | it does | 01:26 |
| ShadowJK | but modem hides it | 01:26 |
| DocScrutinizer05 | that's where I basically came from | 01:26 |
| DocScrutinizer05 | dunno what exactly a stack the bb5 is running, but it got fecked up on my 2G only, while 3G still worked | 01:27 |
| ShadowJK | Like you could maybe see the phonet/isi that's used between modem and omap, but then modem takes the IP and puts it inside gprs | 01:27 |
| ShadowJK | Mine often gets stuck on 3g now. Around the time it started happening operator called trying to send me more 3g saying 3g had been improved recently in my area | 01:28 |
| ShadowJK | I'm guessing "improved" means they told all phones to try a little bit too hard to maintain the 3g icon :P | 01:29 |
| * DocScrutinizer05 wonders how C1/C2 criteria analoga for handover from 3G to 2G are implemented | 01:30 | |
| DocScrutinizer05 | tbh I got no friggin clue about UMTS | 01:31 |
| DocScrutinizer05 | only about GSM | 01:31 |
| DocScrutinizer05 | maybe even more interesting: how's the handover from 2G to 3G defined, since that has to be an addendum | 01:32 |
| DocScrutinizer05 | amendment, augmentment? | 01:33 |
| DocScrutinizer05 | I'm rather sure they hadn't anything for that in original GSM specs | 01:34 |
| DocScrutinizer05 | though, they must have something for genuine roaming | 01:34 |
| *** mvp_ has quit IRC | 01:35 | |
| DocScrutinizer05 | maybe roaming to 3G is not that different | 01:35 |
| ShadowJK | some phones show separate listing for 2g and 3g when you do network search | 01:37 |

| freemangordon | jaska: it uses lzo1 aiui | 10:46 |
| freemangordon | which is supposed to be fast | 10:46 |
| vi_ | what about GPU acceleration? | 10:46 |
| jaska | yeah lzo1 is pretty near to lz4 | 10:46 |
| vi_ | someone must have implemented some kind of compression algo that exploits the features of a GPU. | 10:47 |

| freemangordon | either there or in the queue | 11:13 |
| freemangordon | waiting to be written | 11:14 |
| freemangordon | though I try to play it smart, i.e. I release those (16) pages from the compressed pool with oldest jiffies | 11:15 |
| freemangordon | ans maybe this is one of the probles | 11:15 |
| ShadowJK | I mean so that a read of it doesn't pull it back to compressed pool | 11:15 |
| freemangordon | it does not pull it back | 11:15 |
| freemangordon | it just sits on the flash | 11:16 |
| ShadowJK | so that a read just pulls it into swap cache from flash | 11:16 |
| freemangordon | no | 11:16 |
| freemangordon | reading does not put stuff into te compressed pull | 11:16 |
| freemangordon | only writing | 11:16 |
| ShadowJK | (the normal swap cache) | 11:17 |

| *** FlameReaper has quit IRC | 11:17 | |
| *** FlameReaper has joined #maemo | 11:17 | |
| freemangordon | on reading I am doing a normal READ bio if the page is not in compressed pool (or in write queue) | 11:17 |

| *** pcfe` is now known as pcfe | 11:18 | |

| freemangordon | as finding the oldest pages takes looots of time | 11:19 |
| *** valdyn has joined #maemo | 11:19 | |
| freemangordon | and just free lets say 256 pages from the compressed pool once I am out of memory for compressed pages | 11:20 |
| freemangordon | on a circular basis | 11:20 |
| freemangordon | will try that when I am back home | 11:20 |
| freemangordon | though maybe the best I can do is to not compress at all, but just implement what nokia did (for swap) in a better way | 11:21 |

| deepy | Lucky! | 11:44 |
| freemangordon | well, not exactly lucky, as it was me to propose rpi | 11:45 |
| jon_y | I have a rpi too, but it's sitting in a drawer until I can get some HDMI monitors | 11:45 |
| * jon_y too lazy to setup bootp | 11:45 | |
| *** FReaper has joined #maemo | 11:45 | |
| freemangordon | naah, no monitors, no network, just GPIO and kernel/libc on a bare metal | 11:45 |
| deepy | freemangordon: could still be someone else who gets to do it | 11:46 |
| jon_y | how does the rpi boot up anyway? it's own uboot? | 11:46 |
| freemangordon | deepy: no | 11:46 |
| deepy | Alright let me rephrase then | 11:46 |
| deepy | You could be working in a callcenter | 11:46 |
| freemangordon | after all I am the principal SW engineer here :D | 11:46 |
| jon_y | callcenter now run by rpis | 11:47 |

| freemangordon | hopefully | 11:48 |
| jon_y | I'm stuck doing un-OOP java | 11:48 |
| freemangordon | aah, yeah, got it | 11:48 |
| freemangordon | jon_y: JAVA? poor you :( | 11:48 |
| jon_y | as much claim as it has to being OOP, it can be just as much in the opposite way | 11:49 |
| jon_y | by misusing oop | 11:49 |
| jon_y | yeah, you need to check the underlying class type to use the interface, that kind of retard | 11:49 |
| deepy | I knew a guy who was really into C, he liked to call Object-Oriented Programmers for OOPs | 11:50 |
| *** dhbiker has quit IRC | 11:50 | |
| jon_y | java, like C++ is pretty tame, if used properly | 11:50 |
| jon_y | yeah, I prefer plain C too | 11:50 |
| deepy | I wouldn't know, I suck at C. But I can do Python | 11:50 |
| jon_y | I do perl too, beautiful language if used right | 11:50 |
| *** jas4711 has quit IRC | 11:50 | |
| jon_y | sort of the glue code for in-between application linkages | 11:51 |
| jon_y | wanted to pick up python, but couldn't find a use for it at work | 11:51 |
| deepy | I've seen perl, I don't think you can call it beautiful | 11:51 |
| deepy | web development! | 11:51 |
| jon_y | deepy: is it easy to write C extensions for python? | 11:52 |
| deepy | err, in a way, yes | 11:52 |
| deepy | swig and cython are the best ways I hear | 11:52 |
| jon_y | java has javah, produce C headers for java classes | 11:52 |
| deepy | But I heard it's really easy to screw up the C part and then you'll have segfaulting code | 11:52 |
| jon_y | perl has xs | 11:52 |
| jon_y | yep, all of them have the same issue | 11:53 |
| deepy | Never really understood if that was a problem with C, Python, Cython or the programmer | 11:53 |
| jon_y | so, as a C programmer, you have the responsibility | 11:53 |
| jon_y | all the weight and power of it | 11:53 |
| jon_y | what does python use to generate stubs? | 11:53 |
| deepy | stubs? | 11:54 |
| jon_y | or are you supposed to use the python headers and write from there? | 11:54 |
| jon_y | in java, you could tell it that some methods are supposed to come from the C JNI extensions | 11:55 |
| deepy | I'm not entirely sure, but I think there might be the possibility that Cython or SWIG comes with a tool | 11:55 |
| jon_y | so it generates some stub headers, you use those headers to implement your functions | 11:55 |
| jon_y | I was wondering if python has something like that | 11:55 |
| jon_y | Cython or CPython? | 11:55 |
| deepy | Cython | 11:55 |
| jon_y | never heard of Cython | 11:56 |
| deepy | I think SWIG might go the stubs approach | 11:56 |

| DocScrutinizer05 | jon_y: is this a general advice, or only applicable for *learning* c? | 17:19 |
| jon_y | DocScrutinizer05: I can't say for other languages | 17:20 |
| DocScrutinizer05 | jon_y: tbh I even appreciate syntax highlighting for shellscript in e.g. kate or mcedit | 17:20 |
| jon_y | for C/C++, it's definitely applicable | 17:20 |
| jon_y | well, point is, get rid of the IDE doing all the compiler config, syntax highlighting is fine | 17:21 |
| DocScrutinizer05 | jon_y: I'm not asking abiut which language, but if this advice is meant for experienced programmers as well | 17:21 |
| jon_y | call the compiler yourself, write a makefile or a buildscript | 17:21 |
| jon_y | get familiar with the tools that you use | 17:21 |
| jon_y | once you get the underlying layers, feel free to use an IDE if it improves your performance | 17:22 |
| jon_y | the important part is laerning what the tools actually do | 17:22 |
| DocScrutinizer05 | I think a proper IDE, esp editor with auto-completion, ctags, compile-error feedback to source etc can increase my productivity by factor 2 .. 10 | 17:22 |
| jon_y | before treating everything as a blackbox | 17:22 |
| jon_y | well, when starting, be sure to learn about your tools | 17:22 |
| DocScrutinizer05 | yep, 100% ACK | 17:22 |
| jon_y | I find it painful to lurk on programming forums or mailing list where newbies keep asking about setting up their favorite IDEs to workaround some compile error that their getting | 17:23 |
| jon_y | they don't even understand the error in the first place | 17:24 |
| jon_y | or how to fix it | 17:24 |
| jon_y | espeicially linker errors | 17:24 |
| DocScrutinizer05 | yep | 17:25 |
| *** valeriusL has quit IRC | 17:25 | |
| DocScrutinizer05 | I'm even more radical in that regard, suggesting people start to learn about what's programming by coding in assembler | 17:25 |
| jon_y | things like learning to use readelf, nm, c++filt can save you a lot of troubles | 17:25 |
| *** valeriusL has joined #maemo | 17:25 | |
| jon_y | yeah, I'm fine with starting with asm :) | 17:25 |
| * jon_y actually started with C and made his way downwards to the hardware | 17:26 | |
| DocScrutinizer05 | once you know how the processor works, you appreciate what the compiler can do for you, and you never will abuse it | 17:26 |
| * jon_y now does java, perl, php, C, C++ | 17:26 | |
| jon_y | yup, getting the basics right can save you from years of unlearning | 17:27 |
| *** rm_work has joined #maemo | 17:27 | |
| DocScrutinizer05 | I've seen C++ programs (texteditor) where each single character been a c++ object | 17:27 |
| jon_y | wat. | 17:27 |

| *** FlameReaper has quit IRC | 17:28 | |
| *** khertan has quit IRC | 17:28 | |
| jon_y | luckily I didn't have much to unlearn Java when somebody recommended I start with Eclipse | 17:28 |
| *** FlameReaper has joined #maemo | 17:28 | |
| jon_y | quickly looked up the tools to understand the class loader error messages | 17:28 |
| jon_y | it kind of gets mysterious when IDE builds fine, but get an error running | 17:29 |
| jon_y | especially one as cryptic as telling you X class can't be loaded | 17:29 |

| DocScrutinizer05 | jon_y: check out Qt3 textedit box for richtext. iirc it needs factor 1000 of RAM for opening any size of plain ascii text. Fun bit: on *closing* the textedit box, this even *doubles* | 17:35 |
| *** thetet has quit IRC | 17:35 | |
| DocScrutinizer05 | jon_y: I've seen this in twinklephone, on function "show logfile" | 17:35 |
| DocScrutinizer05 | maybe it's only been factor 100, but anyway - insane | 17:36 |
| jon_y | double?? | 17:36 |
| jon_y | crazy stuff | 17:37 |
| DocScrutinizer05 | and actually closing the display allocated same amount of RAM *again* | 17:37 |
| jon_y | why did it do something like that? | 17:37 |
| jon_y | really bad memleak? | 17:37 |
| * DocScrutinizer05 suspects destructors of all objects got called and thus something cracy happened | 17:38 | |
| DocScrutinizer05 | crazy* | 17:38 |
| jon_y | should be freeing in destructors, not allocating | 17:38 |
| DocScrutinizer05 | blame Qt3 | 17:39 |
| jon_y | I try to be very conservative with C++ | 17:39 |
| DocScrutinizer05 | I argued long time with chief developer Michel deBoer of twinklephone, about replacing that crap by a system("less") call, but he refused to touch that code, argument "less is not posix, thus not available on some of the target platforms" | 17:41 |
| DocScrutinizer05 | (long story short) | 17:42 |
| jon_y | how about letting $PAGER do it, if not, just dump out everything to stdout | 17:42 |
| DocScrutinizer05 | twinklephone is a Qt GUI app | 17:43 |
| jon_y | maybe I don't want any paging | 17:43 |
| *** valdyn has quit IRC | 17:43 | |
| DocScrutinizer05 | "show logfile" been a auxilary function under extras menu in that GUI | 17:43 |

| DocScrutinizer05 | nobody* | 17:44 |
| jon_y | its supposed to put it into a textedit box? | 17:44 |
| DocScrutinizer05 | install twinklephone and test it ;-) | 17:44 |
| DocScrutinizer05 | yep | 17:44 |
| jon_y | doesn't QT have a decent textedit box with scrollers attached? | 17:46 |
| jon_y | maybe qt3 doesn't | 17:46 |
| DocScrutinizer05 | well, I guess that's exactly the one twinklephone used | 17:47 |
| *** FlameReaper has quit IRC | 17:47 | |
| *** arvut has joined #maemo | 17:48 | |
| jon_y | I've done wxwidgets and SWT, I don't think QT is that stupid | 17:48 |
| jon_y | I mean just some scroller and textbox shouldn't be doubling memory | 17:49 |
| *** valdyn has joined #maemo | 17:49 | |
| DocScrutinizer05 | doubling? the doubling happened on close, on top of an already kicking factor of 50, 100, or 1000 (can't recall anymore - probably it's been too insane to keep details in memory) | 17:50 |
| *** M4rtinK has quit IRC | 17:51 | |
| DocScrutinizer05 | I.E for opening 100k of logfile text, Qt allocated let's say 5MB of RAM | 17:51 |
| DocScrutinizer05 | maybe 50 | 17:51 |
| jon_y | I can't imagine a scrollable text box doing that unless something went crazy wrong | 17:51 |
| DocScrutinizer05 | I checked it | 17:51 |
| DocScrutinizer05 | I found it and discussed it and Michel and others confirmed it | 17:52 |
| * jon_y be avoiding qt3 | 17:52 | |
| jon_y | valgrind better be talking | 17:52 |
| DocScrutinizer05 | twinklephone still available for installation on virtually all common distro repositories | 17:54 |
| *** sq-one has joined #maemo | 17:54 | |
| DocScrutinizer05 | will need qt3 libs but so what | 17:54 |
| DocScrutinizer05 | you're able to reproduce my findings in less than 10 minutes | 17:55 |
| DocScrutinizer05 | and I honestly don't think that's particularly twinklephone specific problem, I'm quite sure it's genuine Qt3 textedit box problem | 17:58 |
| jon_y | I sure hope with all that newfangledness in QT4 and C++11 fixes it | 17:59 |
| *** FlameReaper has joined #maemo | 17:59 | |
| DocScrutinizer05 | if they stop implementig each isngle char as a RTF object, I'm sure it will improve ;-P (only handwaving) | 18:00 |

| infobot | DocScrutinizer05 meant: if they stop implementig each isngle char as a rich text object, I'm sure it will improve ;-P (only handwaving) | 18:01 |
| DocScrutinizer05 | but honestly, what else could explain the need of way beyond 10bytes of RAM to store one byte (or even word) of char? | 18:05 |

| freemangordon | i have some POC ramzswap for you :) | 20:47 |
| freemangordon | here http://dox.bg/files/dw?a=cbd27e2587 | 20:48 |
| freemangordon | use "/sbin/insmod /lib/modules/2.6.28.10-cssu3/ramzswap.ko memlimit_kb=16000 backing_swap=/dev/$your_swap_device" | 20:49 |
| *** qwazix has joined #maemo | 20:49 | |
| freemangordon | and have in mind that it is not intended to be used more than lets say 10 minutes :D | 20:49 |
| kerio | freemangordon: does the backing swap have to be exclusive? | 20:50 |
| kerio | freemangordon: also, do you have to enable the swap somehow? | 20:50 |
| freemangordon | vi__: as once you run out of continious (256k in size) blocks on the BSWAP device you are doomed, no defragmentation so far | 20:50 |
| freemangordon | kerio: exclusive? | 20:51 |
| freemangordon | swapon is your friend | 20:51 |
| kerio | freemangordon: can (or must) the backing device be enabled for normal swap too? | 20:51 |

| *** kaziklubey has quit IRC | 20:52 | |
| kerio | i see | 20:52 |
| freemangordon | vi__: have in mind that module is for the thumb mernel | 20:52 |
| kerio | so it's to be used as the single swap device | 20:52 |
| freemangordon | yes | 20:52 |
| freemangordon | single? | 20:52 |
| freemangordon | no, you can add as much swap devices as you wish | 20:53 |
| kerio | i see | 20:53 |
| freemangordon | but it makes no sense | 20:53 |
| kerio | do you get the full-ish size of the backing swap partition with your module? | 20:53 |
| freemangordon | yes. minus 1 eraseblock | 20:53 |
| kerio | wtf is an eraseblock? | 20:53 |
| freemangordon | the block you write at once | 20:54 |
| kerio | i see | 20:54 |
| freemangordon | i.e. 128*4096 in that particular case | 20:54 |
| kerio | i bet NAND swap would be really fast :3 | 20:54 |
| freemangordon | unfortunately we don;t have enough free NAND to use it for swap | 20:55 |
| kerio | sure we do | 20:55 |
| kerio | install fremantle on the eMMC | 20:55 |

| vi__ | I activate ramz with backingswap on sd card with a higher priority than the emmc. | 21:41 |
| freemangordon | ok | 21:41 |
| vi__ | then it grinds to a halt. | 21:41 |
| freemangordon | how big is the partition? | 21:41 |
| vi__ | had to pull the battery. | 21:41 |
| vi__ | freemangordon: ~600mb | 21:42 |
| freemangordon | that's fine | 21:42 |
| freemangordon | vi__: that should not happen (tm) | 21:42 |
| freemangordon | anything in syslog? | 21:42 |
| freemangordon | you should see something like "ramzswap: ramzswap_schedule_write queue[128]" | 21:43 |
| freemangordon | there are some more debug messages | 21:43 |

| freemangordon | vi__: try the opposite, i.e. swapon $sdcard_swap, swapoff /dev/mmcblk0p3 | 21:47 |
| freemangordon | and use /dev/mmcblk1p3 as backingswap | 21:47 |
| freemangordon | oops | 21:47 |
| freemangordon | mmcblk0p3 :) | 21:47 |
| kerio | freemangordon: why would that change things | 21:47 |
| freemangordon | maybe his SD card is too slow | 21:48 |
| freemangordon | or swap partition is badly aligned | 21:48 |

| kerio | akls2: what the enabler does is set things up so that HAM can install CSSU properly | 22:13 |
| kerio | after you ran the enabler once, you just need to do the system upgrade from HAM | 22:13 |
| akls2 | kerio, apt-get upgrade is going to work too? | 22:13 |
| kerio | _Lena: install h-e-n | 22:13 |
| kerio | akls2: use HAM | 22:13 |
| akls2 | ok | 22:13 |
| _Lena | yes i did that allready and i had a keyboard working | 22:14 |

| *** netkat has quit IRC | 22:18 | |
| kerio | _Lena: coldflash is mostly useless | 22:19 |
| DocScrutinizer05 | _Lena: ...since virtually nobody has an idea why (s)he would need it, due to knowledge about what coldflash actually does is not really widespread | 22:19 |
| DocScrutinizer05 | further: h-e-n doesn't impair normal battery charging | 22:19 |
| _Lena | i Thought it was overwriting the coontnt of the nand | 22:19 |
| DocScrutinizer05 | _Lena: actually it's not exactly doing that | 22:20 |
| DocScrutinizer05 | coldflash is needed *only* when NOLO doesn't show up on power-up | 22:20 |
| _Lena | does it reset the register of the bq* chip | 22:20 |
| DocScrutinizer05 | NOLO is the bootloader that shows the dim NOKIA screen | 22:20 |

| DocScrutinizer05 | )except removing battery, or bme or h-e-n explicitly resetting them) | 22:21 |
| kerio | coldflashing is basically just a way to restore NOLO if you blew it up | 22:22 |

| _Lena | i was using the flasher program and started whith the u-key pressed, thats what i did, everything went fine | 22:23 |
| DocScrutinizer05 | sure, but if you followed instructions for coldflashing, you probably didn't do anything useful at all | 22:23 |
| _Lena | yes it was not changing anything | 22:24 |
| *** eMHa__ has joined #maemo | 22:24 | |
| DocScrutinizer05 | if holding u-key actually results in something, you already are beyond the point where coldflash will do something you'd need | 22:24 |
| _Lena | now after playing whith diferent sofwarreinstallations i cant even uns the U-key any more | 22:25 |
| DocScrutinizer05 | I suspect KP52 might load the bq24150.ko kernel module and thus break bme | 22:25 |
| DocScrutinizer05 | _Lena: please stop messing around with flashing and whatnot on a basis of "let's see what this does", rather come here & tell your problem & ask what's next to do | 22:26 |

| DocScrutinizer05 | _Lena: I suggest you reflash to proper stock maemo PR1.3, to get a clean start (unless you got so much nifty config in this system that it's actually worth the effort to 'fix' stuff rather than simply restroing the standard packages after reflash) | 22:37 |
| DocScrutinizer05 | I.E. do a backup with builtin maemo backuptool, then reflash, then restore your apps if really needed, but make sure to uncheck any kernel related stuff from the list of apps to restore | 22:38 |

| _Lena | I swapt the small backup Battery, no change | 22:48 |
| freemangordon | That seems to me like USB port failure creeping | 22:49 |
| DocScrutinizer05 | you did WHAT? | 22:49 |
| freemangordon | DocScrutinizer05: breathe man | 22:49 |
| freemangordon | a smaller capacity battery | 22:49 |
| freemangordon | (I hope :D ) | 22:49 |
| _Lena | also i check whith a multimeter the conectivity from the usb coonector to th usb-test-pads on the boarrd, also ok | 22:49 |
| freemangordon | _Lena: what USB cable do you use? Did you try to use different port on your PC? | 22:50 |
| DocScrutinizer05 | swap of bupbat not fixing *anything* regarding flashing | 22:50 |
| _Lena | now if i use the H-E-N, i can suply the external device whith 5v....that means the usbport off the phone scold be ok to, right ? | 22:51 |
| freemangordon | right | 22:51 |
| freemangordon | so, your USB seems pretty ok | 22:51 |
| DocScrutinizer05 | so what's that nonsense about "flashing without USB" then? | 22:52 |
| _Lena | i am 98% shure it is nothing physical | 22:52 |
| freemangordon | now, try the following: | 22:52 |
| *** foo` has joined #maemo | 22:52 | |
| freemangordon | remove the battery | 22:52 |
| DocScrutinizer05 | for 2 min | 22:52 |
| freemangordon | connect USB cable to both n900 and PC | 22:52 |
| DocScrutinizer05 | (though he swapped bupbat :-S ) | 22:52 |
| _Lena | i could flash it before ! soometimes it was working | 22:52 |
| freemangordon | open the keyboard and press'n'hold "u" | 22:53 |
| DocScrutinizer05 | *sigh* | 22:53 |
| freemangordon | put the battery back, while still holding 'u' pressed and wat for lets say 30 seconds | 22:53 |
| freemangordon | s/wat/wait/ | 22:53 |
| infobot | freemangordon meant: put the battery back, while still holding 'u' pressed and wait for lets say 30 seconds | 22:53 |
| freemangordon | your n900 should be detected by your PC | 22:53 |

| DocScrutinizer05 | and there's no info we forgot to consider | 22:54 |
| freemangordon | _Lena: try what I told you | 22:55 |
| freemangordon | and try that using several different ports on your PC | 22:55 |
| _Lena | english is not may native language, may i amm a little lazy to explain everrything detailed | 22:55 |
| DocScrutinizer05 | we actually don't need explanations | 22:55 |
| *** _rd has joined #maemo | 22:56 | |

| DocScrutinizer05 | irrelevant | 22:56 |
| freemangordon | what about the cable? | 22:56 |
| _Lena | ok, so how can i get the phone back to respond too my usb while pressinh u on powerup ? | 22:57 |
| freemangordon | _Lena: ^^^ | 22:57 |
| _Lena | y testet 2 diferent cabels, whithout change | 22:57 |
| freemangordon | do what I told you | 22:57 |
| DocScrutinizer05 | _Lena: please first do battery-test: device shut down, hold 'u', then plug in fastcharger | 22:58 |
| *** VDVsx has quit IRC | 22:58 | |
| DocScrutinizer05 | verify that usb icon shows up on upper right of NOKIa screen and STAYS | 22:58 |
| freemangordon | DocScrutinizer05: have in mind that usb sign stays only for about 10 seconds when connected to a charger | 22:58 |
| DocScrutinizer05 | nope | 22:59 |
| freemangordon | at least here | 22:59 |
| DocScrutinizer05 | then your battery is empty | 22:59 |
| freemangordon | hehe | 22:59 |
| DocScrutinizer05 | won't flash like that | 22:59 |
| DocScrutinizer05 | that's why it's called battery test | 23:00 |
| freemangordon | ok, I am wrong | 23:00 |
| freemangordon | it stays | 23:00 |
| DocScrutinizer05 | tldya | 23:00 |
| freemangordon | :) | 23:00 |
| _Lena | conecting charger... pone vibrates, display shows the "NOKIA" buut whithout backliight an whithout the usb.symbel in the top right corner, and reboots every 15 or 20 seconds | 23:01 |
| DocScrutinizer05 | _Lena: will you confirm that your battery test worked? or does the USB icon vanish after 10s | 23:01 |
| DocScrutinizer05 | hmmmm | 23:01 |
| freemangordon | hmm, NOLO? | 23:01 |
| DocScrutinizer05 | that is either a fsckdup NOLO by your coldflash, or a broken USB | 23:01 |
| _Lena | it in a loop, but only wher it starts whith a charger conected | 23:02 |
| DocScrutinizer05 | or defect hardware genetrally | 23:02 |
| DocScrutinizer05 | ooh, wait | 23:02 |
| freemangordon | _Lena: where did you get your HW version from when you did the coldflash? | 23:02 |
| freemangordon | DocScrutinizer05: flat battery? | 23:02 |
| DocScrutinizer05 | it's probably weak battery plus messed up rootfs - fits perfectly | 23:02 |
| _Lena | i am not shure if i did a "coldflash" i did flash the vanilla and combind, is this calld coldflash ? | 23:03 |
| DocScrutinizer05 | freemangordon: indeed | 23:03 |
| freemangordon | _Lena: no | 23:03 |
| freemangordon | this is just a normal flash | 23:03 |
| freemangordon | _Lena: do you have charged battery? | 23:03 |
| DocScrutinizer05 | _Lena: your problem is flatbat vicious circle | 23:03 |
| _Lena | no, i got an external charger, also i swapped the battery whith an nokia 5800, batery woorks | 23:04 |
| freemangordon | _Lena: what now, do you have charged battery or you don;t have one? | 23:04 |
| DocScrutinizer05 | no, the symptoms are exactly like battery too flat for flashing | 23:04 |
| freemangordon | too flat for booting too | 23:04 |
| _Lena | i know, but if i disconect the charger, the phone boots up and works for hours !! | 23:05 |
| DocScrutinizer05 | doesn't matter | 23:05 |
| _Lena | so i cant be the batt | 23:05 |
| kerio | is this an original battery? | 23:05 |
| DocScrutinizer05 | battery needs some 80+% for flashing | 23:05 |
| freemangordon | DocScrutinizer05: but it should not enter a reboot loop | 23:05 |
| DocScrutinizer05 | phone only needs 1% fpor booting | 23:05 |
| _Lena | no, but i tryed an original, and the same, not working | 23:06 |
| DocScrutinizer05 | freemangordon: he messed up his rootfs | 23:06 |
| freemangordon | I know | 23:06 |
| freemangordon | but nevertheless NOLO should work | 23:06 |
| DocScrutinizer05 | it does | 23:06 |

| freemangordon | hmm, I missed the part with messed rootfs, what is that supposed to mean. | 23:07 |
| freemangordon | kerio: yes | 23:07 |
| DocScrutinizer05 | don't ask me why it boots without charger connected | 23:07 |
| kerio | boot, charge | 23:07 |

| DocScrutinizer05 | that doesn't mean a thing | 23:08 |
| freemangordon | hmm, he can flash stock kernel from within maemo and try again | 23:08 |
| _Lena | i guess something went wrong whith that bme part | 23:09 |
| *** gn00b has quit IRC | 23:09 | |

| *** _rd has quit IRC | 23:09 | |
| *** _rd has joined #maemo | 23:09 | |
| DocScrutinizer05 | for reflashing it, you need a properly charged battery | 23:09 |
| freemangordon | DocScrutinizer05: could it be that only part of NOLO is broken? | 23:09 |
| DocScrutinizer05 | once you pass the battery test, we'll see what's next | 23:09 |
| DocScrutinizer05 | freemangordon: could, but highly unlikely | 23:10 |
| freemangordon | IIRC it is not signed | 23:10 |
| freemangordon | DocScrutinizer05: it makes no sense otherwise | 23:10 |
| DocScrutinizer05 | and he actually did no coldflash it seems, so why would nolo be broken ;-) | 23:10 |
| freemangordon | _Lena: what did ou do to screw up your rootfs? | 23:10 |
| DocScrutinizer05 | he flashed bfs kernel | 23:11 |
| DocScrutinizer05 | obviously | 23:11 |
| freemangordon | DocScrutinizer05: echo "hello world" > /dev/mtd1 | 23:11 |
| DocScrutinizer05 | that's why I recommend proper reflash | 23:11 |
| freemangordon | (or whatever the mtd num was) | 23:11 |
| _Lena | i think it was the h-e--n installation | 23:11 |
| DocScrutinizer05 | no way | 23:11 |
| _Lena | thats when theprobllems started | 23:11 |
| freemangordon | DocScrutinizer05: kernel can be flashed from within Maemo | 23:11 |
| DocScrutinizer05 | no, that's when they became obvious | 23:11 |

| _Lena | till noow ok | 23:45 |
| kerio | DocScrutinizer05: ip is german too | 23:45 |
| freemangordon | kernel-bfs most probably conflicts with it | 23:45 |
| _Lena | ready | 23:45 |
| DocScrutinizer05 | kerio: :-) | 23:45 |
| freemangordon | ready? | 23:45 |
| _Lena | Unpacking replacement kernel-modules ... Setting up kernel (2.6.28-20103103+0m5) ... Setting up kernel-modules (2.6.28-20103103+0m5) ...

ISI message from new source (10, 00) Found device RX-51, | 23:45 |
| DocScrutinizer05 | it installed all 3 packages? | 23:45 |
| freemangordon | looks ok so far | 23:45 |
| DocScrutinizer05 | looks good | 23:45 |
| freemangordon | _Lena: reboot | 23:46 |
| _Lena | yes, liike the last time | 23:46 |
| freemangordon | what? | 23:46 |
| *** toxaris has quit IRC | 23:46 | |
| freemangordon | hmm, I remember something like that on KP thread | 23:46 |
| DocScrutinizer05 | kernel-flasher (2.6.28-20103103+0m5) ? | 23:46 |
| DocScrutinizer05 | is this correct? fmg? | 23:46 |
| freemangordon | DocScrutinizer05: yes, stock kernel | 23:46 |
| freemangordon | (IIRC) | 23:46 |
| DocScrutinizer05 | :nod: | 23:47 |
| DocScrutinizer05 | just wanted to make sure | 23:47 |
| freemangordon | not sure about the version | 23:47 |
| DocScrutinizer05 | 20103103 looked odd | 23:47 |
| *** guampa has quit IRC | 23:47 | |
| DocScrutinizer05 | Installed: 2.6.28-20103103+0m5 | 23:48 |
| freemangordon | yeah, this is the correct version | 23:48 |
| freemangordon | http://repository.maemo.org/pool/fremantle/free/k/kernel/ | 23:48 |
| DocScrutinizer05 | apt-cache policy kernel | 23:48 |
| DocScrutinizer05 | ;-) | 23:48 |
| freemangordon | :) | 23:49 |
| freemangordon | I am on my PC :P | 23:49 |
| _Lena | ok, at themoment i got usb (storagemode) conection to my pc | 23:49 |
| _Lena | lets see if it will last | 23:49 |
| freemangordon | DocScrutinizer05: And I suspect windoze will BSOD if I type that in cmd :P | 23:50 |
| DocScrutinizer05 | hehehe | 23:50 |
| DocScrutinizer05 | it'll nuke the south half of your country | 23:50 |
| freemangordon | _Lena: if you have mass storage, charging should work too | 23:51 |
| DocScrutinizer05 | indeed | 23:51 |
| _Lena | yes, but i had that before, and later it stopped again | 23:51 |
| DocScrutinizer05 | _Lena: you got h-e-n installed? | 23:51 |
| freemangordon | _Lena: would you check which kernel runs now? | 23:52 |
| DocScrutinizer05 | _Lena: could you `wget http://enivax.net/jk/n900/bq27200.sh` | 23:52 |
| DocScrutinizer05 | _Lena: then execute that script | 23:52 |
| freemangordon | DocScrutinizer05: i2ctools? | 23:52 |
| DocScrutinizer05 | h-e-n | 23:52 |
| freemangordon | aah | 23:52 |
| freemangordon | yes | 23:53 |
| freemangordon | DocScrutinizer05: does it nees bme to be stopped? | 23:53 |
| freemangordon | *need | 23:53 |
| DocScrutinizer05 | nope | 23:53 |
| freemangordon | ok | 23:53 |
| *** adb has quit IRC | 23:53 | |
| DocScrutinizer05 | anyway a ps x|grep bme|grep -v grep would help too ;-) | 23:54 |
| freemangordon | DocScrutinizer05: if bme does not run dsme will reboot the device | 23:54 |
| DocScrutinizer05 | should yield 2 lines which _Lena can paste here | 23:54 |
| freemangordon | ps x? | 23:54 |
| _Lena | everything went fine, complaining not enough poower to charge (current sensing ok) then disconected the cable and not working again | 23:54 |
| DocScrutinizer05 | ooops, that's my proper ps | 23:55 |
| freemangordon | _Lena: hmm, and what about if you connect the wall charger? | 23:55 |
| DocScrutinizer05 | _Lena: there's sth fscked up in your kernel modules or initscripts or whatever | 23:55 |
| DocScrutinizer05 | I still suggest full reflash | 23:56 |
| DocScrutinizer05 | well, COMBINED reflash | 23:56 |
| freemangordon | DocScrutinizer05: deffinitely | 23:56 |
| freemangordon | could it be that it is PC to blame? | 23:56 |
| DocScrutinizer05 | if there been kernel-bfs, there might've been other weird stuff as well | 23:57 |
| DocScrutinizer05 | anyway check with fastcharger! | 23:57 |
| freemangordon | _Lena: check which kernel runs !!! | 23:57 |
| _Lena | okk i executed the script | 23:57 |
| DocScrutinizer05 | indeed :-D | 23:57 |
| _Lena | shows nothing | 23:58 |
| DocScrutinizer05 | nothing? | 23:58 |
| DocScrutinizer05 | aah you neet root dor that | 23:58 |
| DocScrutinizer05 | need | 23:58 |
| DocScrutinizer05 | for | 23:58 |
| freemangordon | for :P | 23:58 |
| _Lena | i know, but nothing | 23:58 |
| DocScrutinizer05 | o.O | 23:58 |
| DocScrutinizer05 | well, not that important now | 23:58 |
| _Lena | just the promt | 23:59 |
| freemangordon | uname -a? | 23:59 |
| _Lena | Nokia-N900:~# sudo ./bq27200.sh Nokia-N900:~# | 23:59 |
| DocScrutinizer05 | it would just read out bq27200 chip and tell about *true* current to/from battery | 23:59 |
| DocScrutinizer05 | as well as true bat voltage | 23:59 |
| _Lena | Linux Nokia-N900 2.6.28.10-bfs10 #1 PREEMPT Wed Jan 4 22:28:20 EET 2012 armv7l unknown | 23:59 |
| freemangordon | the fuck?!? | 23:59 |
| DocScrutinizer05 | _Lena: sudo doesn't work like that | 23:59 |
