The MontaVista driver that has been posted on the list that I think is from MontaVista for the PLB TEMAC with very minor modifications to get it to work at speeds other than GigaBit. A driver I wrote for the LocalLink TEMAC that works limpingly. I have been unable to figure out how to get a receive interrupt from the LocalLink TEMAC so receives are polled and performance is poor. I have pretty much abandoned work on it - my client wants the smallest possible FPGA footprint BUTanother OS I am porting requires interrupt driven IO and we are looking for a single minimal hardware implimentation for all platforms. Anyway, if anyone wants the LL TEMAC in its current state I can post it. Currently it sends fine. It drops about 50% of all received packets - but that is probably debugging overhead and poll rate tuning. -- Dave Lynch DLA Systems Software Development: Embedded Linux 717.627.3770 dhlii@dlasys.net http://www.dlasys.net fax: 1.253.369.9244 Cell: 1.717.587.7774 Over 25 years' experience in platforms, languages, and technologies too numerous to list.

Unfortunately, I can't post the driver port publicly because it's not GLP'd, as far as I know. We only needed a 10/100 mac, so we didn't bother with a TEMAC. I got the obp and enet directories to compile but I crash on link with an undefined reference: ********************************************** [root@bockhoefer linux-2.6.17.6]# make CHK include/linux/version.h CHK include/linux/compile.h GEN .version CHK include/linux/compile.h UPD include/linux/compile.h CC init/version.o LD init/built-in.o LD .tmp_vmlinux1 drivers/built-in.o(.init.text+0x246c): In function `fbcon_bmove': drivers/video/console/fbcon.c:1887: undefined reference to `init_etherdev' make: *** [.tmp_vmlinux1] Error 1 [root@bockhoefer linux-2.6.17.6]# ********************************************* I will work on this more today.

Hopefully I can pick up where you left off. We would require an interrupt driven TEMAC ^ permalink raw reply [flat|nested] 6+ messages in thread
