Hi,
I am working on GESBC-9260. I have downloaded linux-2.6.25 kernel, the patch from "
www.maxim.org.za/at91_26.html", the kernel configuration from "
www.at91.com/linux4sam/bin/view/Linux4SAM/LinuxKernel" and Debian based file system from Glomation website. I have extracted Debian as the root filesystem and changed the bootargs to "console=ttyS0,115200 root=/dev/nfs nfsroot=192.168.2.102:/home/jagan/9260/rootfs ip=192.168.2.167::192.168.2.1:255.255.255.0:eth0 init=/bin/init". I build the kernel, downloaded the uImage via u-boot (at 0x21800000) and able to boot. But when Debian is mounted, it is taking a long time (I mean, few minutes) to get the GESBC shell. Following is the boot process:

Can anyone tell me, what was the issue? What changes need to be done with /etc/init.d/rcS script?
Also, let me know, how to extract ' 9260rootfs.img'? I tried by making RAM Disk image, but could not. Can anyone tell me the steps in-detail?
Thanks & regards,
Jagan
