Using random address 8E:A2:E8:DD:E2:73 > phy0: Link is up - 100/Full > transmission timeout > T transmission timeout > T transmission timeout > > But, whether I connect the cable or not, it always shows "phy0:Link is up - 100/Full". Have a look at the output of md -s /dev/phy0. You should see valid phy registers, not 0xffffffff. I have exactly the same problem on an i.MX21 board (proprietary design). I have used the imx21ads to start from. md -s /dev/phy0 returns 0xffffffff. Any ideas how to correct this (the smc91c111 base address is 0xd2c80000) ? Here is the devinfo output : barebox:/ devinfo devices: |----imx_serial0 |----cs0 |----ramfs0 |----devfs0 |----mem0 (defaultenv) |----mem1 (mem) |----cfi_flash0 (nor0, self0, env0) |----cfi_flash1 (nor1) |----mem2 (ram0) |----smc91c1110 |----miidev0 (phy0) |----eth0 |----imxfb0 drivers: imx_serial ramfs devfs smc911x smc91c111 miidev cfi_flash mem barebox:/ devinfo miidev0 base : 0x00000000 size : 0x00000000 driver: miidev no info available for miidev0 no parameters available barebox:/ devinfo smc91c1110 base : 0xd2c80000 size : 0x00000000 driver: smc91c111 no info available for smc91c1110 no parameters available barebox:/ devinfo phy0 no such device: phy0 barebox:/ devinfo eth0 base : 0x00000000 size : 0x00000000 driver: none Parameters: ipaddr = 10.32.50.10 ethaddr = 00:1A:09:20:00:17 gateway = 10.32.51.148 netmask = 255.255.252.0 serverip = 10.32.51.148 barebox:/ |
