Hi All, I have a pair of BBB's that I bought from Canada Robotix. They are both Rev C boards from Element 14. I've been running debian on a micro SD card on each of them. The one board had been running a web server for about 2 months straight, but suddenly lost Ethernet capabilities one day. Both the Ethernet LED's stay ON solid even when no cable is plugged in. I tried to rule out software by loading up a couple different OS's but none of them can connect to my network. I even tried flashing an experimental version of debian from the beagleboard.org wiki but that did not work either. When I boot into debian now I notice the ethernet lights blink for a bit then stop and stay on solid, and I get messages from dmesg like:
root@beaglebone:/var/lib/cloud9# dmesg | grep phy [ 0.000000] Booting Linux on physical CPU 0x0 [ 2.715169] 47401300.usb-phy supply vcc not found, using dummy regulator [ 2.830812] 47401b00.usb-phy supply vcc not found, using dummy regulator [ 3.392979] davinci_mdio 4a101000.mdio: detected phy mask fffffffe [ 3.399823] libphy: 4a101000.mdio: probed [ 3.399859] davinci_mdio 4a101000.mdio: phy[0]: device 4a101000.mdio:00, driver SMSC LAN8710/LAN8720 [ 13.783697] net eth0: phy found : id is : 0x7c0f1 [ 13.783894] libphy: PHY 4a101000.mdio:01 not found [ 13.788720] net eth0: phy 4a101000.mdio:01 not found on slave 1 [ 16.863473] libphy: 4a101000.mdio:00 - Link is Up - 100/Full [ 46.943180] libphy: 4a101000.mdio:00 - Link is Down [ 71.703444] libphy: 4a101000.mdio:00 - Link is Up - 100/Full [ 79.783276] libphy: 4a101000.mdio:00 - Link is Down [ 111.023649] libphy: 4a101000.mdio:00 - Link is Up - 100/Full [ 233.103186] libphy: 4a101000.mdio:00 - Link is Down [ 369.103554] libphy: 4a101000.mdio:00 - Link is Up - 100/Full [ 385.183238] libphy: 4a101000.mdio:00 - Link is Down etc...... etc.... Does anyone have experience with this type of problem?
