Yes. Both U-Boot and Linux exhibit problems at 1000mbit. Both work without errors at 100mbit. > Does running with root file system mounted over NFS work on this > board? Does it work at 1000mbit, too? > 100mbit: yes 1000mbit: no If I boot up the board with the ethernet cable in a 100mbit port, then move the cable to a 1000mbit port, the NFS code says "server not responding" in <10 seconds. > Did you try and re-check the memory controller initialization? > See Dave's comments in reply your message.
