      It is observed that MAC Enable sequence (MAC CONTROL register update) is changed in SDK 9.1 release.

      Observing CRC failure in packets sent from CPSW in stress power cycle test with SDK 9.1 MAC enable sequence (as below), and the possibility is very low which is about 1/1000

      • Clear MAC_CONTROL register
      • Set GMII enable = 1
      • Set full-duplex and GMII mode

       
      If we revert the sequence to earlier release (as per below) then issue is not observed

      • Clear MAC_CONTROL register
      • Set full-duplex and GMII mode
      • Set GMII enable = 1
