HOWTO: Build and Flash Motorola's kernel from source

[ted01]

unpack-bootimg.pl and repack-bootimg.pl din't seem work in the link anymore? Do you have any other source link? Thank you

[j@$$yCliq]

Get ready to wait a while because de prebuilt repository is quite big
Once all of the above have finished lets set the prerequisites to the TAGS specified in the README.txt

$ cd ~/moto-prerquisites/base 
$ git checkout android-1.5r3

$ cd ~/moto-prerquisites/libhardware
$ git checkout android-1.5r3

$ cd ~/moto-prerquisites/libhardware_legacy
$ git checkout android-1.5r3

$ cd ~/moto-prerquisites/msm7k
$ git checkout android-1.6_r1

$ cd ~/moto-prerquisites/prebuilt
$ git checkout android-1.5r3

Can anybody update this??
ive searched around and this is the only one ive found for cliq :/ ive gotten up to those instructions menioned after that i dont know what to replace it with
cause i was able to replace everything else without problems
im not demanding i just would love to create my own kernel (2.1 of course)

Ya man, instead of android-1.5r3, you put in android-2.1_r1. This will get you to the 2.1.5 source If you get the 2.1.5 source, it has a read me in it that will give you all of the new changes.

$ cd ~/moto-prerquisites/msm7k
$ git checkout android-1.6_r1

$ cd ~/moto-prerquisites/prebuilt
$ git checkout android-1.5r3

what happen if i change all the 1.5 and the one that say 1.6 to 2.2?

I'm using 2.1 official update on my orange dext. It runs without any problems. Today I downloaded the 2.1 kernel source from motorola and built it successfully by going through this guide. I extracted the config file from the 2.1 official kernel for building the kernel source.

I packed the new zImage into boot.img by using repack-bootimg.pl and flashed it successfully to /dev/mtd/mtd0 but the phone is not booting. it is stuck at the 'M' logo screen. phone goes into recovery mode without any problems.

I'm using gcc4.2.1 for building the source.
any idea why this is happening?

Afaik If u only want to build the kernel the only trying that you need from the android tree is the prebuild directory, for the toolchain. So it won't matter which version you checkout.

If you adb logcat when booting, do you see something?

adb logcat shows -wating for the device- and nothing else
but it prints lot of info when stock kernel is booting..

I found the problem and fixed it. repack.pl was setting some wrong kernel cmdline options when creating boot.img. I used a hex editor to find the kernel cmdline of the stock kernel and used the same for my kernel. Now its booting properly..

I've written a new guide for Kernel building. You may find it easier. I'll post it here probably tomorrow.
