Where can I find AT91SAM9260 Linux source files?
On AT91SAM9260-EK CD is only Linux bin file.
Why ATMEL does not provide Linux sources with crosscompiler and instruction how works with Linux on AT91SAM9?

Atmel works with TimeSys and with the Linux community.
If you want commercial supports, then contact Timesys.
If you want to work with the Linux community, then
you can download the linux kernel and apply
the patches from the maixm.org.za/AT91_26.html
An easy way of doing what you want is to download
my buildroot script and run it

Hi there

There's also
http://kernelnewbies.org/Linux_2_6_22
and look at the ARM Architecture-specific changes to see what's already in the kernel.
