Custom kernel for Éclair (LCR v1.7 and 1.6)

July 2, 2010

Must I flash your mod_100.15 update?
Do not know if you tried to flashed OC kernel in 1.100.15.FET original ROM?

Thank you for your advising ! :lol: :D

I use it with mod and it works O.o

Is there someone who use 1190 boot?

July 3, 2010

Two questions:

Does a nandroid backup include boot?

and

Has anybody successfully used the 1170mhz patch, or is it just for novelty?

Chances are (very) low the 1.2GHz kernel would boot, but perhaps there's a liquid out there that can match the nexuses :lol:.

Nandroid does backup boot, so yes.

Hey guys.

I'm just wondering, how can i go back to the original 768mhz Kernel ?

Cuz i tried google navigation yesterday in my car while the phone was plugged in the lighter socket.

The phone heated up (setCPU reported something like 45°C) and the battery icon in the notification bar had an exclamation mark in it (i don't know what it means but it doesn't look good)

Maybe the 920mhz Kernel is responsible for this overheating matter ? What do you guys think about this ?

The exlamation mark means that the battery reaches the maximum temperature. The 45C is the maximum temperature, defined in kernel if I remember good.

Is it dangerous if i keep the phone plugged in ? while the max temp is reached ?

I have probed to search something in the source, but I didn't find anything yet about what's happening in this case at kernel level, the kernel changes the battery status, and sends a battery error log, this is sure. At Android level I don't no what's happening in this case.

I think now that it's better to remove the charger and leave the phone alone for awhile.

Hmm got worse battery lifetime with LCR1.6 883mhz patch :-(

With clean LCR1.6 i got 48hours. With 883mhz patch i get ~24hours. -25% battery during 9hours of sleep. Before i got minus 1% per hour. doh...

Any body got same problem and have solution?

It seems SVS causes random reboots.

I cloned phh's kernel tree, reverted SVS commit, now 920 MHz worked quite stable for two days.

I got 883MHz kernel for LCR1.6, and I recharged my phone for ~36h ago, and got more then 50% battery to go.

So I think you've done something weird :3

Are you using profiles in setCPU? How does the profiles settings look like.

What is SVS ?

Can't we just have 1 kernel for all? Just use Koush's anykernel script. It describes it here:

http://wiki.cyanogenmod.com/index.php/How_...el_port_for_CM5

Wow I just discovered this. So just checking, the kernel source for CPU speeds is defined in acpuclock-8x850a.c?

460800 is the fastest clock speed at 1v then?

Which kernel is built to this right now? ...

My setcpu.txt then (nvm. Autodetect works)

I see these frequencies available:

	{ 0, 128000, ACPU_PLL_1, 1, 5, 0, 0, 14000, 2, 0, 1000},

Compared to what pershoot is using for the Nexus One, we are still setting voltages a bit higher than we can achieve for the lower frequencies. We are already at lower operating voltages than the Nexus One for the mid range frequencies. We should also be able to define 128000 at 0.95v for undervolting. If the CPU is the same I don't see why we can't just use this table for reference :) http://github.com/pershoot/nexus-kernel/bl...lock-scorpion.c

whoa! great observation!

i would like to try to compile a custom kernel (i'm a long time linux user) but can someone point me to a tutorial for cross compiling and build boot.img?

i'm asking here since i don't have internet connection at home and don't have time to search a lot at work :| i've seen a lot of informations in this thread but nothing summarized (at least for my searches)

thanks

Quite easy: grab a xcompiler (I use the ones from CodeSourgery) for ARM-EABI architecture, and then make with the CROSS_COMPILE environment variable set to the path of the bin of the cross-compiler you've just downloaded.

After the kernel is done, take it from arch/arm/zImage and build the boot.img with the mkbootimg binary.

this is payed app, isn't it? can someone point me to a free/oss/trial one? does a gcc cross compiler for arm (which is the correct one?) exists?

for me not work..

mm.. actually i started using apps2sd with stock kernel and after that started using 880Mhz kernel.

i've activated apps2sd via latest malez recovery

download started, what about kernel sources? wich is the correct version to download? (i can use git/cvs/whatever)

thanks for your patience! :)

grazie! :D
