| LjL | buZz, yes, well, i MIGHT have just overwritten my bootloader with a kernel that might not boot | 00:00 |
|---|---|---|
| buZz | at least you have backups now :) | 00:01 |
| buZz | sorta | 00:01 |
| LjL | yeah i tried to install the kernel-power package from repositories, although i already had some kind of kernel-power installed but i wanted to make sure everything was up to date | 00:02 |
| LjL | but it informed me that it would replace my current "U-Boot kernel" with it | 00:02 |
| LjL | i clicked out of the dialog, but it seemingly proceeded anyway | 00:02 |
| bencoh | LjL: you should be able to boot a different kernel from usb iirc | 00:07 |
| bencoh | I wonder if that goes for uboot (loading uboot through usb) actually | 00:07 |
| LjL | bencoh, oh i haven't rebooted yet after this potential incident anyway | 00:07 |
| LjL | i'm going to try making sure U-Boot is installed first | 00:08 |
| bencoh | ah, so you're still fine :) | 00:08 |
| LjL | but U-Boot won't update/reinstall because it's missing kernel-modules. i think i'm gathering now that's because nokia.com repositories are down and i need to replace them | 00:08 |
| bencoh | here u-boot-flasher and u-boot-tools are installed | 00:08 |
| bencoh | ~repos | 00:08 |
| infobot | somebody said repos was "deb http://maemo.muarf.org/apt-mirror/mirror/downloads.maemo.nokia.com/fremantle/ssu/apps/ ./ ;; deb http://maemo.muarf.org/apt-mirror/mirror/downloads.maemo.nokia.com/fremantle/ssu/mr0/ ./", or see http://wiki.maemo.org/Repository#List_of_Maemo_repositories, or see ~jrrepos | 00:08 |
| LjL | i am doing the .install clicking | 00:10 |
| LjL | i wonder if i have a QR reader installed for copypasting things without squinting to look at microb | 00:10 |
| LjL | so anyway... how am i meant to install kernel-power *while* making sure it doesn't overwrite uboot? | 00:13 |
| *** Cor-Ai_ has joined #maemo | 00:13 | |
| bencoh | you need the -bootimg package iirc | 00:13 |
| bencoh | kernel-power-bootimg that is (and not kernel-power-flasher) .... afair | 00:14 |
| *** louis_ has joined #maemo | 00:15 | |
| LjL | gotcha - i had installed the latter indeed | 00:15 |
| LjL | so i will remove it, convince uboot to install itself without whining like a child, then install bootimg, and reboot | 00:15 |
| *** Cor-Ai has quit IRC | 00:16 | |
| *** Cor-Ai_ is now known as Cor-Ai | 00:16 | |
| LjL | uhm, does "multiboot-kernel-power" help me get kernel-power to be the default kernel in uboot without editing things myself? the description isn't clear | 00:17 |
| bencoh | I wonder why someone uploaded rp-pppoe to extras* | 00:17 |
| bencoh | doesn't make much sense to me, but meh :) | 00:17 |
| buZz | we have fake ethernet over usb, dont we? | 00:18 |
| buZz | so i guess, some ISPs still use pppoe, go online with n900 directly? hmm | 00:18 |
| buZz | maybe not :P | 00:18 |
| LjL | my god i have such naughty things installed | 00:18 |
| LjL | like aircrack, but that's nothing | 00:18 |
| LjL | i have an ad blocker! how am i even not in prison | 00:18 |
| buZz | o m g | 00:19 |
| LjL | plus, it sure looks like some of this stuff tries to boost the FM transmitter to powers or frequencies that jeopardize national security | 00:20 |
| LjL | way to be a terrorist, ljl | 00:20 |
| buZz | excellent, now go hack the gibson | 00:20 |
| buZz | did you bring your own skateboard or do you need to borrow one? | 00:20 |
| LjL | are you kidding me? skateboarding sounds dangerous | 00:21 |
| LjL | i'm already scared enough of when i have to take my hand off the rail in the bus to reach the ticket machine | 00:21 |
| bencoh | :] | 00:23 |
| buZz | then at LEAST custom paint your keyboard | 00:23 |
| buZz | you cant hack like this | 00:23 |
| LjL | ha i got you there! | 00:24 |
| LjL | i just bought a mechanical keyboard | 00:24 |
| LjL | it's on its way from Amazon (the hacker store) | 00:24 |
| LjL | and it has COLORED LEDS | 00:24 |
| LjL | straight from the leetest hacker factories in mainland China | 00:24 |
| bencoh | buZz: too much angelina for you | 00:24 |
| buZz | i saw http://www.boredpanda.com/hipster-retro-typewriter-keyboard-lofree/ today | 00:24 |
| buZz | bencoh: yeah the botox is going to my head | 00:24 |
| LjL | i think i saw that... i bet it's that one.... | 00:24 |
| LjL | oh, no, it was another one | 00:25 |
| LjL | this one is actually... | 00:25 |
| LjL | something resembling attractive? | 00:25 |
| buZz | yeah i didnt dislike it directly | 00:25 |
| buZz | i gotta go pickup a Model M like .. 50 meters from my house | 00:25 |
| buZz | keep forgetting when i step out the door ^_^ | 00:25 |
| LjL | the other one i saw was both tacky and $200 | 00:26 |
| LjL | the one i bought was €53. Bluetooth. | 00:26 |
| buZz | nice nice | 00:26 |
| LjL | "The software from this catalogue might cause tsunami even if you live hundreds of kilometers inland and if you sue Nokia about it you will achieve nothing. Install?" man that sounds scary | 00:26 |
| LjL | the un-nice thing is that only an ANSI version of it exists, and i need ISO layouts | 00:28 |
| LjL | so i'll have to never type <, > or | again | 00:28 |
| LjL | i suppose i'll cope by taking pictures of stuff my console prints and then OCRing them instead of using redirection | 00:29 |
| buZz | at least there is that conveniance for you | 00:32 |
| buZz | praise cheeses | 00:33 |
| bencoh | LjL: which repository is that? | 00:33 |
| LjL | bencoh, just the mirror of the Nokia one. actual message might have been slightly exaggerated for comedic effect. | 00:34 |

| LjL | how dangerous does it sound to you to try to resurrect my dead battery by stopping bme, swapping batteries real fast, and restarting bme | 00:41 |

| *** Pali has quit IRC | 01:01 | |
| LjL | i see | 01:01 |
| LjL | well, more importantly for the time being: is current U-Boot broken, or am i? | 01:01 |
| LjL | the package i have is "u-boot-flasher" aka "U-Boot with kernel 2.6.28-omap1" | 01:01 |
| DocScrutinizer51 | false assumptions. N900 charges flat battery | 01:01 |
| LjL | it wants to update itself, but to do that, it depends on kernel-modules, and if i try to install kernel-modules on my CSSU system, apt-get hilariously tries to remove the entire world | 01:02 |
| LjL | DocScrutinizer51, well, i couldn't seem to find a way to charge mine before it spontaneously rebooted, while with the new cell, i managed to boot. i had this rescueOS thing linked earlier but now that i have a new battery, didn't really check it out | 01:03 |
| DocScrutinizer51 | well the battery is dead | 01:04 |
| DocScrutinizer51 | unless you got a rotten rootfs causing the bootloop | 01:06 |
| DocScrutinizer51 | ~flatbatrecover | 01:06 |
| infobot | Remove battery for 1 minute. Insert battery. Plug powered ***NOKIA WALLCHARGER*** to device. Watch steady amber. Let sit and charge. Do NOT try to boot. After 30 min, you got either a) a booted up N900, b) flashing amber which means you can boot, c) steady amber shut off -> start over again with ~flatbatrecover while already searching for a new battery. CAVEAT! Only works when ~rootfs OK (no ~bootloop) | 01:06 |
| bencoh | yeah my bad, hotswapping a dead battery doesn't work :) | 01:06 |

| pkill9 | DocScrutinizer51: i suppose there's nothing wrong with sudo, it's just cleaner if you don't need to use it :) | 02:23 |
| * bencoh used to have uucp on his laptop to automagically push mails with a proper local smtp relay | 02:23 | |
| pkill9 | bencoh: i added myself to uucp group on my laptop to send AT commands to the phone as user | 02:23 |
| bencoh | ah | 02:24 |
| bencoh | now I'm disappointed :p | 02:24 |
| pkill9 | so i thought maybe that was the group i had to add the n900's user to in order to use those AT commands also | 02:24 |
| bencoh | has anyone ever worked with libnotify on maemo btw? | 02:24 |
| pkill9 | bencoh: aww, why you dissappointed? :P | 02:25 |

| bencoh | pkill9: I thought you actually used uucp on n900 | 02:25 |
| pkill9 | tbh i don't know why uucp is :P | 02:26 |
| bencoh | even more disappointed then :> | 02:26 |
| pkill9 | all i know is i had to add myself to that group to send AT commands | 02:26 |
| DocScrutinizer51 | find /dev -iname '*usb*' -ls | 02:45 |
| DocScrutinizer51 | you'll find uucp on the group | 02:46 |
| DocScrutinizer51 | on systems where this works. On mine USB is group dialout | 02:46 |
| DocScrutinizer51 | not sure, just a guess | 02:47 |
| DocScrutinizer51 | I further *guess* pnatd uses libisi to access network device/socket whateverthename | 02:49 |

| DocScrutinizer05 | does it work? well, depends on what you expect it to do | 20:51 |
| buZz | well i would assume the swapping faster-than-normal would be motivated by keeping-phone-on | 20:52 |
| buZz | besides that, i see 0 point to this :P | 20:52 |
| *** inz has quit IRC | 21:05 | |
| DocScrutinizer05 | it is a feasibility study for *how long* you need to 'keep the phone on' without battery attached. Dosn'T mean there's an implemented and tested solution for such keeping the phone on during battery swap, other than the test I did with charger atached which worked to keep phone running for hours without battery | 21:05 |
| DocScrutinizer05 | the concept was to have a 'mobile charger USB stick consisting basicaly of a supercap you charge in USB VBUS boost mode so it works as aux power supply, and that speed swap was for estimating how long such a device would need to provide power | 21:07 |
| DocScrutinizer05 | anyway I'm pretty proud of this little stunt :-) | 21:11 |
| buZz | good :D | 21:19 |
| *** inz has joined #maemo | 21:27 | |
| DocScrutinizer05 | the 'problem' with battery hotswap is: bq24150 charger chip doesn't start "charging" in a millisecond, so removing the battery when it's not already "charging" will result in blackout of system | 21:32 |
| DocScrutinizer05 | if you want to test: make sure battery is sufficiently depleted so it gets charged when you attach charger, and do just that. Then `stop bme`, make sure backlight is on level 5 and always on (to keep system consumption above the level where bq24150 stops charging), then swap battery and `start bme` | 21:34 |
| DocScrutinizer05 | no need to hurry, I ean my N900 for several hours without battery this way | 21:35 |

| DocScrutinizer05 | just when you're in a region with poor signal (so TX will power up) and maybe - to make matters worse - you're on 2G (which is more 'bursty' on power consumption), odds are your system will brown out when modem starts TX for whatever reason | 21:37 |
| DocScrutinizer05 | fun 'experiment': connect phone without battery to Nokia charger. waaaaaait. after quite a long time the steady amber emergency charging LED signal will shine up, indicating that bq24150 tries to "charge" *something*. That something must be CPU idling in bootloader waiting for battery voltage go up to a level where it could actually boot up system. So the whole set is worth nothing for real, but intriguing to watch ;-) | 21:41 |
| DocScrutinizer05 | (CPU) euther the main CPU or the modem CPU | 21:42 |
| DocScrutinizer05 | either* | 21:42 |
| DocScrutinizer05 | quite scary when you think same situation (of "system" eating energy for no visible effect) might happen on a quite depleted battery as well, depleting it even more | 21:43 |
| DocScrutinizer05 | well, maybe not really, since it's most likely the VBUS 5V that 'power on' the main CPU. Those are not existent when inserting depleted battery. Dunno if pressing power button could result in same pathological system state | 21:45 |
