DP83849C: Prerequisites for MII loopback test
Part Number: DP83849C
Dear DP83894c Experts,
I would like to run a RJ-45 loopback test; that is with a plug on the RJ45 that loops the TX data to RX.
Post reset, are there any registers that I must configure in order to see a successful loopback of an ethernet frame?
With Auto-Neg set to 100M, you shall see the link is up and data transfer shall go thru.
We are glad that we were able to resolve this issue, and will now proceed to close this thread.

I proceeded with the RJ-45 loopback before answer arrived and it worked. It works without auto-negotiation. It works with 100 bits/sec set. I guess this is not abnormal , yes ?
In reply to Rochus:
Tx and Rx are seperate and you can setup link using external loop back.
