[U-Boot-Users] BOOTP timeouts

[U-Boot-Users] BOOTP timeouts

[himbA]

Hi,

I've been debugging smc91c111 lan driver in u-boot for several days now 
and found the fix that eliminates (at least on my board) the need to 
have debugging enabled on the driver and still run OK. The routines for 
send and recieve were lacking save/restore of PTR and PNR regs on start 
and end of routine, respectively. I will post a patch as soon I clean up 
the code.

I have another question - has anybody experienced BOOTP timeouts using 
smc91111 driver ?
To me it happens once in ~50-100 reboots of the board and after that the 
systems keeps on trying to send BOOTP requests but it doesn't leave the 
chip (tcpdump is not showing any packets on the wire). This would be 
output on console:
[...]
