However, during the kernel booting, it complains that "No network devices available," So I figured I probably didn't enable the ethernet driver in the kernel. >From doing "make menuconfig", under "Device Drivers" --> "Network device support" --> "Ethernet(10 or 100Mbit)", I checked the box of both "Ethernet (10 or 100Mbit)" and "PowerPC 4xx on-chip Ethernet support." I then save/exit the menuconfig to compile the kernel again. I've attached the error output at the bottom. The virtex eth device is not the same as 4xx on-chip Ethernet, so CONFIG_IBM_EMAC will not work. You need the xilinx_enet driver (which is not in mainline). It might be in MontaVista's 2.6 tree. I think people have posted patches for it to this list, so try searching the archives. (I don't have a link off the top of my head.)     The MV 2.6 Xilinx_edk based TEMAC driver has been posted to this list several times.     As of the last incarnation I tried it had no MII/PHY support and you had to manully change the speed of the driver 10/100/1000 by editing the code.     Otherwise it worked with the PLB FIFO TEMAC, that I am using, and should with others.     I have a polled driver that works with the LL TEMAC.     I am nearly finished a PLB FIFO TEMAC driver that includes working autonegotiation and does not use the Xilinx_edk.     But right now it has a receive problem - packets come in they look good but linux silently discards them.     I have virtually the same code working under GHS Integrity. -- Dave Lynch DLA Systems Software Development: Embedded Linux 717.627.3770 [EMAIL PROTECTED] 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.
