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
