I am using custom-made eval board in which LS1021A is populated.

We are evaluating gigabit ethernet PHYs using this evaluation boards.

Attached the log file for more information on BSP, U-Boot.


Sometimes, on power-on it doesn't detect the PHY. 


starting network interfaces...
[ 5.132126] net eth0: could not attach to PHY "


However, On doing the hard reset It detects the PHY.

Attached log file for both the scenarios.

Can you please help me out in resolving this issue?

Thanks in advance.
