1. OK
2. OK
3. "driver failed to report" means you do not have calibrated battery - not problem with module
4. OK

You have directory /sys/class/power_supply/bq27200-0 where are all exported values. So it is working.

Will be able to try that after the weekend...travelling in a few hours and need the phone there.

However, last night when reflashing, my saved WiFi-connection also resetted. So I used 3G mode the whole time, experiencing the same issues after installing power. Doesn't disabeling power saving only effect WiFi-settings? And if it does, might it be that changing this setting might solve my problems with 3G as well?

Thanks!

Ah, I assumed a wifi conn. The 3G observation refutes my conjecture. There is no power setting for packet connections. So the issue lies elsewhere. I enabled my skype account and have no issues with online status and slowdowns (k-p 49).

Something had to have changed- did you change volting profile etc etc.. Does the problem appear with kernel-power and std clock settings or only when oc &/or uv?

It might have started though when entering the WiFi-coverage, noticed it shortly after I came home. Last package installed was Desktop Calender Widget, which has been running 3 days non-stop before with no problems. Will try k-p 49 as soon as I come back and made a good backup... Been installing deleted apps for quite some hours now. Thanks again for your help!

(Is this still the right place to discuss / troubleshoot this issue? Should I start a new thread? If yes, where?)

I would like to ask what you did on the current u-boot+kp49.bin?

because it now works with my n900. Just wanna give you an update and know what you did

Re: [Announce] kernel-power unstable v49

Here is small howto in order to combine the kp49 with u-boot by yourselves (these also are the steps to install KP49). Combined image could also exists on pali's site, but in this particular case, it was outdated, so I have to combine it myself:

!!! Please be aware that you understand what you are doing, just copy/paste below commands, will not lead you to the end, some details are missing (like becoming root, making temp folder etc...). You should have basic knowledge for working on linux command prompt, before try to follow such guides.

* Install needed software to repackage and download

Code:

apt-get install -y wget flasher mkimage

* Download packages

Code:

wget http://atrey.karlin.mff.cuni.cz/~pal...er49_armel.deb

wget http://atrey.karlin.mff.cuni.cz/~pal...er49_armel.deb

wget http://atrey.karlin.mff.cuni.cz/~pal...er49_armel.deb 

wget http://atrey.karlin.mff.cuni.cz/~pal...er49_armel.deb

* Install them

Code:

dpkg -i kernel-power_2.6.28-10power49_armel.deb

dpkg -i kernel-power-modules_2.6.28-10power49_armel.deb

dpkg -i kernel-power-flasher_2.6.28-10power49_armel.deb

dpkg -i kernel-power-bootimg_2.6.28-10power49_armel.deb

* Extract fisaco image from kernel package

Code:

dpkg --fsys-tarfile kernel-power_2.6.28-10power49_armel.deb | tar -xf - \ boot/zImage-2.6.28.10-power49.fiasco

mv boot/zImage-2.6.28.10-power49.fiasco .

* Download u-boot.bin from pali's site

Code:

wget http://atrey.karlin.mff.cuni.cz/~pali/u-boot.bin

* Unpack fiasco image

Code:

flasher -u -F zImage-2.6.28.10-power49.fiasco

* Make uImage from zImage

Code:

mkimage -A arm -O linux -T kernel -C none -a 80008000 -e 80008000 \

-n "Power Kernel v49" -d zImage uImage

* Get pali's u-boot combined builder script

Code:

wget http://atrey.karlin.mff.cuni.cz/~pal...ted-builder.py

* Start it

Code:

chmod u+x ./u-boot-combinated-builder.py

./u-boot-combinated-builder.py

* Start updater

Code:

softupd -vv -s --local

* Flash the kernel

Code:

flasher --local -f -k ./combined.bin

* Reboot

Your battery is not calibrated, read again

Next it check if battery is calibrated (CI flag) and if not it does not export capacity values (because they are bad). See how to calibrate: http://talk.maemo.org/showpost.php?p...&postcount=846

O
I have followed the step.
1. bq2700.sh when full charge
2. disconnect electrical plug
3. Nearly full discharged, run bq2700.sh 5
4. when under 3248, EDV changed to 1, and device shutdown.

thats it? anything I missed? sorry for disturbance...

pali	2011-10-07 09:03

Re: [Announce] kernel-power unstable v49

Check with bq27200.sh if you have flag CI:0 If no, you did someting incorrectly. When doing learning cycle, make sure that after battery is fully charged you stopped bme. (When bme is running, it shutdown device before learning cycle is complete)

Re: [Announce] kernel-power unstable v49

what mean of CI be 0, I found mine is 1
Leaning cycle means bq27200.sh 5? Thats means I no need wait the battery nearly discharged and just start this step when battery full charged?

you need to have 0 (1 means error). If CI is 1 bq27x00_battery kernel module ignore all capacity properties (and report error). Plug wall charger and fully charge. Unplug charger and discharge. When BME notify "Battery empty", stop bme and monitor battery status with bq27200.sh script. When EDV1 switch to 1, plugin wall charger, start bme (it could turn off display) and fully charge. This calculate battery capacity - but it could not calculate correct values (so do learning cycle again)...

That mean I need to do 2 Times bq27200.sh 5...by the way thanks

Re: [Announce] kernel-power unstable v49

i want to install kp49 and i downloaded all needed files to my PC and cloned to my N900.
i heard that packages must be installed in order... in which order, could you remind? (if it wouldn't i'll just do "dpkg -i *.deb" but i know it is not the case)

also do you consider kp49 as "almost stable"? i wanted to test thoroughly the compcache/ramzswap :)

well minor instability issues wouldn't make me cry, because i have kp48 from repo, and my phone has tiny unstabilities (it reboots when much stress to the machine IO (network or disk) and in same time random factor appears)

pali i think they doesn't have your latest patched kp48 in repository, do they? so i thought it would be easier to just skip to kp49, and keep if stability pleases me or just come back if it is unpleasant for me.

note that i'm not overclocking yet (to not void waranty until it ends), and my kp reports as 48 and it seems to not have ramzswap module

EDIT:and im having problem that battery-meter sometimes stuck on 5mAh (0.4%) and unstucks (steps up) only after long charging
it looks i don't have any suspicious *patches i have bme on and i believe i don't use bq27x00-battery module but i use really funky conky script and i don't know if it touches that

PS: is kp49 so unstable that during kernel flashing sh|t may happen? i ask because i've never done remote reflash (the one with usb and "U" key) and don't want to have to.
PPS: I was supprised how easy it was to just flash the kp48 kernel, and that i don't have to do mysterious tricks like rebooting without battery, etc. the only things i believe i have not tried yet are repartitioning MMC and multiboot
PPPS: i have my n900 bought this summer holidays from third party, but i'm advanced in using computer devices, so i'm neither noob nor pro at these boards.

Huh? the old 1 before I posted works with hardware revision 2204 so I was asking what changes you made? Did you found out the problem already? Will try the new one soon Im still currently using my n900 as phone :p

Re: [Announce] kernel-power unstable v49

Hi pali I don't know what you did(Since i don't see any updates on pali-master git) but it is working flawlessly now. Probably the reboot loops was on the kernel's side? And you got it fixed on kernel power 49?

Update: Pali your latest combinated image doesn't work again on my n900 with hardware revision 2204 but the one "before you updated few hours ago" was working fine and stable on my n900 :(

Re: [Announce] kernel-power unstable v49

My IR port (at least with QtIrreco), is not working any more since I installed v48.
Some people are having the same problem: N900 infrared problem

Can someone confirm this? Is there anything I can do?

Thanks in advance.

EDIT: I tried "TV-B-Gone" and it worked. The problem is just with QtIrreco.

Finally I can use bq27x00, thanks you very much
1 more thing, is it normal when I rmmod for charging, the phone will reboot after few min?

if bme is running and you modprobe/rmmod bq27x00_battery it is normal (you cannot use bme and module together).

but if your phone reboot when bme is stopped and you modprobe/rmmod - that is bad!

it is bad! somewhere is error. Can you enable R&D mode and attach syslog/dmesg or mtd log partition?

sorry but in your logs are nothing interest - no errors. Please try output of mtd log partition (/dev/mtd2) - Be carefull, manipulating with mtd can damage your device!

is rebooting always happen, or only once?

Re: [Announce] kernel-power unstable v49

hey i found how to install kernel manually (kernel, then modules, then flasher)

i found kp49 from 06-X-2011 is very stable for the test version
it looks that is as stable if it will be release version not testing version
compcache is stable too, depending of size it either speeds up or slow down. so need to set the size wisefullly. it's sad that stats doesn't work for this version of kernel. (I'd like to know how much of swap compress well)

THANKS PALI FOR KERNEL POWER v49, it's great
