Testing the INCA-IP Ethernet Module in loopback mode
I am trying to test the ethernet module of INCA-IP in the loopback mode using "U-boot version 1.2" .The MIB counters show that the packet is getting forwarded from the CPU port to the LAN port, and not getting looped back at the LAN port.
I was expecting the rxUnicastPkt of the LAN port and txUnicastPkt of the CPU port to increment on successful loopback operation.However, the same is not observed in the values displayed.Please let me know how I can verify the loopback.
The contents displayed by the MIB counters before sending the ping requst are as follows
