Tool/software: Linux
Hi,
I am using a DP83867IRPAPT PHY on a custom dm8147 board. I am able to send data but am not able receive packets.
1. I am using u-boot on my board. I have connected my board to my laptop through a ethernet cable. I am running Linux Ubuntu 16.04 on my laptop.
2. I am doing a ping from my board to my laptop.
3. I am running wireshark and am to see the ARP request from the board and the ARP reply from the laptop back to the board.
4. What i see, is ping fails. Which makes me believe that the Tx is working however Rx is not working.
5. Can i do a reverse loopback so that if i send a ethernet packet from the laptop, it is looped back. If so, how do i do that.
6. Also, can i generate packets from within the PHY and try to do a external loopback to find that the Rx path between phy and RJ45 connector is proper. If so, How can i do that. How do i know if the packets are recieved properly.
I request you to help me in debugging or provide pointers to fix the same.
Thanks,
