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: [...] SMC91111 MAC addr from EEPROM: 00:c4:0e:43:36:68 BOOTP broadcast 1 BOOTP broadcast 2 BOOTP broadcast 3 BOOTP broadcast 4 BOOTP broadcast 5 SMC91111: memory allocation, try 1 failed ... SMC91111: memory allocation, try 2 failed ... SMC91111: memory allocation, try 3 failed ... SMC91111: memory allocation, try 4 failed ... SMC91111: memory allocation, try 5 failed ...

SMC91111: memory allocation, try 10 failed ...

Retry count exceeded; starting again BOOTP broadcast 1 [...]
