[U-Boot-Users] MIPS: AMD Alchemy au1x00 ethernet problems

[geoff cleary]

Hi 
I am seeing a problem with network support on the AMD dbau1550 eval board (and our own board based on Au1550). It seems that after one network command, no further packets can be sent. The minimal case that shows the problem is to include the ping command. The first ping will succeed; any other network commands time out. I have successfully loaded large files using tftpboot command and confirmed the image loaded correctly. Trying the command again fails with TX timeout. 
 
Has anyone seen this problem or have any suggestions as to what is going on? 
 
We are building little endian. I have tried Joseph Chiu's buffer 0 patch. 
 
Thanks 
Geoff
