Thank you,Daixiwen.

I use signaltap to watch the mac_rxd and mac_rx_dv,but no signal can be captured. So I set these signals to others iOS and watch them by oscillator. The four bits frame are as same as the wireshark's display.

Now I don't know how to watch the red in tse or sgdma_rx. I still confused with the 'mac_rx_dv', currently I connect the signal to rx_col in tse_mac. I'm not sure this step.

Besides I read the data sheet of DP83848K, it says loop back can be completed by connect rx_dv to tx_en,rxd to Txd.

Best regards.
