Hi all,
I'm getting an undefined instruction error at the end of the bootp command:
Filename 'kernel_img'.
Load address: 0xc0f00000

Does anyone know how to solve this problem?

What does your memory map look like? Maybe you are overwriting data or
code needed by U-Boot?
Also, consider problem number 1: memory errors dues to incorrect RAM
initialization.

No, I'm not going to explain it. If you can't figure it out, you
didn't want to know anyway... :-)

I've considered that but unless I'm missing some config item, that looks good.
I've got 32MB ram:
arch_number = 0x00000186

boot_params = 0xC0000100
DRAM bank = 0x00000000

-> size = 0x02000000
ethaddr = 00:08:EE:00:63:B2
ip_addr = 192.168.0.13
baudrate = 115200 bps

Sounds very tight to me. Download to a much lower address and check
what happens...
And please don't full-quote.
