Hi all,

I have a big problem that I couldn't understand. I have i.mx28 evk. I use default sb linux with sd card. I want to up eth0 and mount my host pc with nfs. 



ifconfig eth0 netmask

eth0: Freescale FEC PHY driver [Generic PHY] (mii_bus:phy_addr=0:00, irq=-1)
root@freescale ~$ PHY: 0:00 - Link is Up - 100/Full


mount -t nfs -o nolock /mnt


Sometimes mounting is ok, sometimes it lates, but sometimes it cannot be mounted. 

Mostly I see act led flashes very fast but there is no activity. I check with ifconfig, there is no increase on any packets and on ethernet switch act. led doesn't flash.


When I couldn't mount nfs, I tried down up like below and got error response;

ifconfig eth0 down

ifconfig eth0 up

FEC: MDIO read timeout

eth0: could not attach to PHY

ifconfig: SIOCSIFFLAGS: Connection timeout
