Hi RY,
Thank you very much for pointing out this with the details. As you mentioned, 'RMIIClock_setup()' function is not needed in ICSS mode. Actually it should have come under the macro 'USE_CPSW_DRIVER'. We will track/ followup with this bug internally.
Regarding your second post, we can't see 'RMIIClock_setup()' function causing link down/communication issue here in our ICEv2 board.
We can communicate with the board (ping as well as EIP tool) with the released app as well as by commenting out 'RMIIClock_setup()' in 'TaskFxn' in main.c - We believe this behavior caused us failing to find this bug during our testing.
We will investigate on this behavior and will come up with more details soon-
Regards,
Nijin
