Kernel Conf File For Kernel 2.6.24.4-yonggun, I've solution provided for cross compile Options

[abm_y4k]

Can someone provide me the kernel config file for this kernel version?

If possible the patches as well?

I am trying to rebuild the kernel for hostap injection support with PRISM2_DOWNLOAD_SUPPORT enable.


Thanks,

It already has packet injection. I don't know about download support. Why not just ask 2or0? He was very helpful when I asked for injection.

He seems very busy. I've sent him two PM and made some comment on his blog... but still no response yet.

[Capn_Fish]

Hmm...My impression is that he hasn't made the his patch list/sources/config public yet (he has to if asked to comply with the GPL, AFAIK). I suspect it's due to either hosting concerns, lack of time, or just the fact that it's a moving target and would be extra work to post the new stuff each time.

[abm_y4k]

I got PM reply from 2or0. Very helpful.

I'll start my compiling today.


Cheers.

Care to share the details (source, how to compile, etc.)?

[abm_y4k]

I will... but I am still on the way setting up scratchbox.

Hi,

I've successfully recompiled the kernel and the hostap driver for injection with firmware upgradeable.

It seems hard to find a proper way to do the cross compile so I'll like to share my steps with you all.

CODE

wget http://www.codesourcery.com/gnu_toolchains/arm/portal/package2549/public/arm-none-linux-gnueabi/arm-2008q1-126-arm-none-linux-gnueabi-i686-pc-linu
x-gnu.tar.bz2

tar xjf arm-2008q1-126-arm-none-linux-gnueabi-i686-pc-linux-gnu.tar.bz2

mv arm-2008q1 /usr/local

export PATH=/usr/local/arm-2008q1/bin/:$PATH

cd /usr/src

*download the kernel conf and patch file from http://yonggun.tistory.com/66
*save the kernel source to /usr/src

tar zxvf kernel-2.6.6.24.4.tar.gz

mv config linux-2.6.24.4/.config

cd /usr/src/linux-2.6.24.4

make zImage ARCH=arm CROSS_COMPILE=arm-none-linux-gnueabi-

make modules ARCH=arm CROSS_COMPILE=arm-none-linux-gnueabi-

make modules_install

* kernel should be in /usr/src/linux-2.6.24.4/arch/arm/boot/zImage
* modules should be in /lib/modules/
* make sure flash the kernel with the newly built modules

This might be very helpful for many ppl, forum admin should consider sticky this.
Thanks,

Thanks,

Been looking for this for such a long time , will give it a try on the weekend.
Thanks so much!

NP.

I've only tested and confirmed its working on C3100

Questions:

1. Are we missing the step to patch the kernel sources?

2. Does this cross-compiler support distcc?

3. Will

CODE

make uImage

instead of

CODE

make zImage

build for uBoot?

4. Could someone point me in the direction of the "fastfpe" and "cpufreq" patches?
(4a. They need to be applied separately right?)

5. How about tetsu's pressure sensitive patches? http://translate.google.com/translate?hl=e...cial%26hs%3D4zc

1. get the patch from yonggun's site. and apply it using patch -p0 < patch-2.6.24

2. Not sure.

3. I've not tried with uImage... since I am on sharp loader. I found uBoot give me a lot of trouble.. so I stick with the sharp

4. fastfpe and cpufreg should be in that patch provided by 2or0

5. tetsu's patch are only refer to kernel 2.4.x not for 2.6.24.4

Hope helps.

[radiochickenwax]

Thanks a lot for your help. I'm not very experienced with kernel building and still having troubles.


1.==============================================

1. get the patch from yonggun's site. and apply it using patch -p0 < patch-2.6.24

I'm not sure if this is right, but I renamed the patch from http://yonggun.tistory.com/66 to patch-2.6.24.4 and applied using

CODE

patch -p1 < patch-2.6.24.4

instead of -p0 (-p0 asked me on every step which file to patch). Is this patch valid for 2.6.24 only?

It also says on http://yonggun.tistory.com/66 that

These are patched with angstrom patches and without cpufreq.

I think the correct page for the patches is: http://yonggun.tistory.com/64, but I don't know for sure.

2.==============================================

doing

CODE

make zImage ARCH=arm CROSS_COMPILE=arm-none-linux-gnueabi-

works okay.

3.==============================================

doing

CODE

make uImage ARCH=arm CROSS_COMPILE=arm-none-linux-gnueabi-

immediately after says:

running

CODE

make clean

before doing

CODE

make uImage ...

seems to work, but I haven't flashed yet. It gives "arch/arm/boot/Image" instead of "arch/arm/boot/uImage" as I'd anticipated.

My next question is: how do I get uBoot to boot the kernel from SD or CF... i.e. why are there four copies (hda1,hda2,sd1,sd2) of the kernel on http://yonggun.tistory.com/72? Is this just to tell the kernel where the rootfs is?

You need to modify the kernel .config file and recompile it:

CONFIG_CMDLINE="console=ttyS0,115200n8 console=tty1 noinitrd root=/dev/hda1 rootfstype=ext3 rootdelay=1 rw fbcon=rotate:1 dyntick=enable debug"

change root=<device you want to boot it at>
