v2: Fixed typo: CS8900_BUS32 -> CONFIG_CS8900_BUS32 Added more descriptive printf in cs8900_init as suggested by Wolfgang Initialize 'priv' data structure in cs8900_initialize()
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'.

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
