[U-Boot-Users] Rx-buffer overlow

[Josef Angermeier]

Dear u-boot-users,

I am verly lucky, that i got u-boot running on my custom MPC875-board.
Just a few things make still some trouble: 

the ping-command (and all other network transfer commands) in the u-boot
shell often doesn't work, and the following debug output is generated:

fec_recv[249] err: 802
fec_recv[249] err: 2802
fec_recv[249] err: 802

According to the Rx-buffer-status bits, an overlow takes place. So ping
just works if there is less network traffic.  But why ? - is the receive
buffer to small, the CPU to slow ? 

thanks for your advices,
best regards

Josef

At which clock frequency are you running your CPU?

Best regards,
