[U-Boot-Users] Network problem in u-boot.

[André Berggren]

Hi again.

I made some more tests and found that the old 405enet driver wont halt forever like the old 440 and the latest 4xx driver does. The old 405enet only outputs "ENET Speed is 100 Mbps - FULL duplex connection" sleeps for a while and then resumes the transfer.

Observe that the problem only occurs when another computer send packets to u-boot or broadcasting on the network. If non of this occurs the transfer is always successful.
  
I enabled debug and got following output:

Hi!
Yes the mac is valid.
I use 100Mbps FD and bootp to get an adress. U-boot gets IP 172.18.22.66 and netmask is 255.255.255.0

I´ll try to enable debugging later and post the results.

And do you use a valid MAC address? Did you try to enable debugging in the 4xx 
ethernet driver? If not, please do this and post some results here.
