Hello everybody out there,
I'm new to the linux programming world and have some problem when
practicing for the first time. I have compiled a uClinux image for an
ARM7 CPU. The compiling has been done successfully. However, when I
loaded it on skyeye, it hung although there was no error messages shown.
I don't know if I did it correctly.
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.
Here is the log:

Because I don't have a real board to test it therefore I have to use
skyeye. But skyeye seems to have not much support. If any of you know
the syntax of skyeye.conf file please show me as I have no idea about
it. I really appreciate your help.
This is what I use:
cpu: arm7tdmi
mach: at91

mem_bank: map=M, type=RW, addr=0x01000000, size=0x00400000
