Download buildroot from http://buildroot.uclibc.org/downloads/
I'm using 2009.02 release.
Download eldk for compiling
here
This is an iso image. Burn it and install it. I installed 2 versions (with software FP and with hardware FP) in /usr/local/cross. Actually we need to compile with software FP.
#tar -xvjf buildroot-2009.02.tar.bz2
#cd buildroot-2009.02
#make menuconfig
Now select:
Target architecture - arm
Target architecture variant - arm920t
Target ABI - EABI
Toolchain:
Toolchain type : External binary toolchain
Core C library : libc-2.6.so
Libraries to copy : clear all
Enable large file support - check
Enable RPC - check
Use software floating point by default - check
Build c++ compiler - check
External toolchain path : /usr/local/cross/usr
Target filesystem options:
Uncheck all
tar the root filesystem - check
Compression method : bzip2
Exit, save
#make
Root filesystem exists in binaries/uclibc
Now copy all libraries from /usr/local/cross/arm/lib to rootfs/lib. I need to explore what libraries we need exactly.
Deploy image to the board. I'm booting from nfs and in this configuration you can see linux booting in console.
Thanks for help to Leshak

I tried your method, but I'm getting this error..
copy_toolchain_lib_root: lib=libc.so.0 not found
I have cross checked many times all the paths are ok
Just copy all libraries and everything should be OK
Hello,
I'm trying to do just what you tell in this post, and i'm having lots of setbacks. I managed to compile it one time correcty and now all it keeps giving me are fakeroot errors.
Anyway, wouldn't it be possible to publish your mini2440_config file? Or give a few more details. Software versions, support libraries, development tools, etc?
Best regards,
Luís Silva
I just figured out that buildroot version that I used is no longer available. I have updated my post. And I found that sometimes you need to delete build directories and build everything from beginning.
Hi,
What tool are you using to compile the kernel? There is an option to compile it within buildroot. Didn't you never use it?
Best regards,

Hi.
I didn't compile kernel inside buildroot. I compiled it separately with eldk. Currently I'm using 2.6.29-rc6 with LeshaK patch(you can find a link to his site in my blog home page)
