Hi all,
in context of one of my emails last week: http://sourceforge.net/mailarchive/forum.php?thread_id=3364771&forum_id=...
I'm wondering about how many people are using the LAN91C111 driver without significant problems. There is (just was :-) a fat signed/unsigned bug in drivers/smc91111.c which is significant at NIOS plattforms when you are using MAC addresses with address elements above 0x7f. Example: 00:07:ed:0a:a4:7b goes over to 00:07:ed:ff:a4:ff inside the chip. Simple solution:
static char smc_mac_addr[] = { . . . };
have to be:
static char unsigned smc_mac_addr[6] = { . . . };
In attatchment you will find my smc91111_fix patch. It includes some other minor fixes I've made. This patch has been working successful at NIOS Stratix and Cyclone boards.
Please try out and patch CVS tree.
Best Regards,
