Phil, Are you sure the first 2 scenarios are not due to DHCP problem? If the EVM is able to send DCHP request then it means Ethernet is OK. Connect the EVM Ethernet port thru a hub/switch to see if the LED comes on (detecting the carrier). For u-boot, you can try the similar thing (thru a h

Phil, BJ, We have not seen problems as you described in our daily use of tftp download in u-boot and using NFS in kernel. If you can gather more info as to what specific condition can cause this to happen then it will be very helpful. In u-boot occasionally we saw 'checksum errors' or 'T' (t

Hi, We have done performance tests using iperf to measure the throughput from DM9000 ethernet driver. The 26Mbps reported in the datasheet was done using TCP. The unpublished number using UDP is about 30Mbps rx and 45 Mbps tx. These were very optimal numbers since no other application was runn
