I hate to be the bearer of bad news, but AFAIK non of the public trees have a driver for the TEMAC. Xilinx EDK 8.1 does include drivers for the TEMAC and it *should* generate a working BSP for MontaVista Linux 3.1 (patched 2.4 kernel). It should also work with the linuxppc-2.4 tree. If you want it on a 2.6, you'll need to port the driver. Regardless, the Xilinx driver code is NOT GPL'd, so beware. > So I have the following questions to ask. > > 1.

The TEMAC and EMAC are totally different devices, and I haven't looked to see if TEMAC driver uses the same API, but it is probably a good starting point. Cheers, g. -- Grant Likely, B.Sc. P.Eng.
