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.
