Hi all,
I'm getting an undefined instruction error at the end of the bootp command:

Filename 'kernel_img'.

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.

Best regards,

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
env_t       = 0x00000000
boot_params = 0xC0000100
DRAM bank   = 0x00000000
-> start    = 0xC0000000
-> size     = 0x02000000
ethaddr     = 00:08:EE:00:63:B2
ip_addr     = 192.168.0.13    
baudrate    = 115200 bps

My TEXT_BASE starts at 0xc1fc0000 and I'm loading at 0xc0f00000 (~1.2M)

Sounds very tight to me. Download to a much lower address and check
what happens...

And please don't full-quote.
