Hi Greg,
Thanks for your reply. I'm using 2.6.19 as I got the whole distribution from
uclinux website.
Could you please explain a bit more about the meaning of the configuration in
the skyeye.conf file? Or guide me to somewhere I can look for explanation?
Thanks,
Thai.

What kernel version are you using?
It can be useful to use gdb/ARMulator for problems like this.
At least you can trace through the start of execution. The
gdb/ARMulator is buggy though if you are using 2.6 kernels.
But you can still debug the startup.

This is what I use:
cpu: arm7tdmi
mach: at91
mem_bank: map=M, type=RW, addr=0x00000000, size=0x00004000
mem_bank: map=M, type=RW, addr=0x01000000, size=0x00400000
mem_bank: map=M, type=R, addr=0x01400000, size=0x00400000, file=boot.rom
mem_bank: map=M, type=RW, addr=0x02000000, size=0x00400000
mem_bank: map=M, type=RW, addr=0x02400000, size=0x00008000
mem_bank: map=M, type=RW, addr=0x04000000, size=0x00400000
mem_bank: map=I, type=RW, addr=0xf0000000, size=0x10000000
lcd: state=off
