I'm using latest U-Boot and Linux 2.6.37 from Denx. Once in Linux I can ping my own IP-Address but not any other device in my network. The Link LED is on when connected to the network but when pinging some other device nothing is being transmitted (Traffic LED is off). If - before booting - I'm using any network command under U-Boot (which is calling eth_init()), the interface works fine after that under Linux also! In that case the kernel prints the line: PHY: f003000:00 - Link is Up - 100/Full So I'm not sure whether the Linux driver does not initialize the PHY correctly or whether I should be running a command under Linux that makes the interface work. I've played around with ifconfig but that didn't get me any further. Under sysfs I can see that the MAC address is assigned correctly but: carrier = 0 (should be 1) duplex = half (should be full) operstate = down speed = 10 (should be 100) To workaround I could make u-boot run eth_init() always but that doesn't seem the right approach to this. Any ideas? Many Thanks, Stefan.
