custom kernel

[tritron]

What is involved into creating custom kernel. I want to create custom kernel with udev patch and enabling bluetooth and i2c. How to test with tftp do I need serial cable

[dolphs]

that also caught my interest, thus to compile for the latest kernel ( atm: 2.6.39 )
Think I will start here @ http://archlinuxarm.org/developers/building-kernels

Moreover I am a bit puzzled:

uname -a shows:

Linux server 2.6.31.6_SMP_820 #100 SMP Sun May 29 04:53:45 EDT 2011 armv6l ARMv6-compatible processor rev 5 (v6l) Oxsemi NAS GNU/Linux

while if I look in /usr/src it says clearly: linux-2.6.39-ARCH

while in /lib/modules I clearly see both:
drwxr-xr-x 3 root root 4096 Jul 6 22:01 2.6.31.6_SMP_820
drwxr-xr-x 3 root root 4096 Jul 7 07:38 2.6.39-ARCH

Went something wrong while flashing?

"Went something wrong" no.
This isn't the stock 2.6.3x.x kernel.

Yes, I need to work a guide.. I am also working on getting the whole thing into 1 package for autobuilds, but at the same time, there is also the fact that we have to write it to NAND... yeah.. Fun.

Basic gist: at the moment, there is no guide as to which bits of source are needed, and we've slightly modified the stock config / sources as they are.

I will get back to you.
