Thanks. That's better, but no cigar yet.

I now get this:

TRAB # run load
Using CS8900-0 device
TFTP from server 192.168.1.1; our IP address is 192.168.3.68
Filename 'trab/u-boot.bin-wd'.
Load address: 0xc100000
Loading: data abort
pc : [<0df6b254>]          lr : [<0df4c694>]
sp : 0df1bb74  ip : 00000004     fp : 0000083c
r10: 0df79ca0  r9 : 000000c0     r8 : 0df1bfd8
r7 : 0df1c100  r6 : 0df1c140     r5 : 0000002a  r4 : 0000005c
r3 : 07000300  r2 : 0000002a     r1 : 0df79ca0  r0 : 0df1c100
Flags: nzCv  IRQs off  FIQs off  Mode SVC_32
Resetting CPU ...

Decoding PC and LR gives:

PC: 0x0df6b254 -- 0x0df6b228 + 0x002c   cs8900_send
LR: 0x0df4c694 -- 0x0df4c668 + 0x002c   eth_send

Placing a few printf()s indicates that it crashes in the writel()
following the rety: label. Looking at the code, the
"&priv->regs->txcmd" looks a bit fishy to me. I played around a bit
(guessing for "priv->regs->txcmd" and "&(priv->regs->txcmd)" but this
doesn't change behaviour.

Best regards,

Wolfgang Denk
