[U-Boot-Users] MPC8260 FCC ethernet fails.

[Ho Lee]

Hi Folks, 

I am porting u-boot 1.1.1 to MPC8260 based board, which uses FCC3
for ethernet. Basicially it is working; it sends and receives ICMP packets (ping)
and DHCP packets. But when I try to download a file via TFTP protocol, it 
loses packets frequently (once per about 10 packet transfers), eventually 
results in timeout. I monitor the packet transfers by tcpdump, and the server 
surely sends a packet, but the buffer descriptor of FCC says the RX buffer 
is empty. What may cause this problem? I would appreciate any comments. 

Regards,
Ho
