I developed a custom board for Collibri VF50.
I added a second ethernet (LAN8710A) to my custom board.
I enable the SMSC PHY driver from kernel configuration.
Device Driver [*] Network device support ---> -*- PHY Device support and infrastructure <*> Drivers for SMSC PHYs
I used the provided dual-eth devicetree example to get the second ethernet available.
I can see the fec0 and fec1 both in my system.
When I tried to run ‘ifconfig eth0 up’ i get the following error message:
root@colibri-vf:~# ifconfig eth0 up [ 26.912416] fec 400d0000.ethernet eth0: no PHY, assuming direct connection to switch [ 26.920436] libphy: PHY fixed-0:00 not found [ 26.924766] fec 400d0000.ethernet eth0: could not attach to PHY ifconfig: SIOCSIFFLAGS: No such device
When I remove the 4.7k (or 1.5k) pull-up resistor for MDIO signal, i get the following message:
root@colibri-vf:~# ifconfig eth0 up [ 121.223140] fec 400d0000.ethernet eth0: Freescale FEC PHY driver [Generic PHY] (mii_bus:phy_addr=400d0000.etherne:00, irq=-1) [ 121.249667] IPv6: ADDRCONF(NETDEV_UP): eth0: link is not ready [ 123.220167] fec 400d0000.ethernet eth0: Link is Up - 10Mbps/Half - flow control off [ 123.227960] IPv6: ADDRCONF(NETDEV_CHANGE): eth0: link becomes ready
Phy detected as Generic PHY, link shows up, but no communication!
Please help me to solve this ethernet issue.
