Ethernet related no such file issue

[vineethhegde]

i have a board based on i.MX6Q processor. while testing i got log as shown below.

cat: can't open '/sys/devices/platform/enet.0/net/eth0/operstate': No such file or directory

/root/ethernet.sh: line 9: [: ==: unary operator expected

cat: can't open '/sys/devices/platform/enet.0/net/eth0/operstate': No such file or directory

i suspect issue is related to the ethernet.

Please suggest the solution

Hello vineeth113 754,

This issue seems to be related to the Ethernet driver so I would suggest reviewing the driver implementation.

Are you using the same driver as the i.MX6 SABRE board? It may serve as a starting point but some modifications may be necessary for your custom board.

we observed this issue in 8 boards out of 100.

Ans: we are using ethernet phy chip from Micrel(KSZ9021RNI).
