I'm working with a 5282 based board and am having ethernet problems. I know the ethernet hardware is sound because it works in uClinux. The fec appears to be working somewhat in u-boot, (I'm using Zach's modified fec code). But still appears to be timing out. I have the debugging code on and I'm trying to pick up a dhcp, I'm getting:
u-boot-> dhcp BOOTP broadcast 1 BOOTP broadcast 2 packet received packet received Receive from protocol 0x806 Got ARP packet received packet received Receive from protocol 0x806 Got ARP packet received packet received Receive from protocol 0x806 Got ARP BOOTP broadcast 3 BOOTP broadcast 4 BOOTP broadcast 5
Retry count exceeded; starting again
So it appears to be communicating, just not quite right. Zach, you originally mentioned that the timers might not be getting initialized correctly. Where are the timers initialized in the code? Do you have a patch for this?
I'm on a 100 base-T network, is that a problem? Has this code been tested at 100?
If anyone has been down a similar path before I could use some debugging tips.
thx, NZG.
