AM6548: PRU Ethernet driver crash

AM6548: Issue with getting the IP address on AM6548 Custom board with SDK 8.2

Part Number: AM6548

Hi TI,

We are using custom board with AM6548 SR 2.0 chipset. We have 4 ethernets 2 on each ICSSG 1 and 2 . 

SDK Version : 8.2

We are facing issue multiple times on all 4 ethernets, we many times face issue in getting the IP address. DHCP servers are all running well. We did not observe IP issue on SR1 EVM with SDK 8.2  but we dont have EVM with SR2 to confirm if this occurs .

Any solution/ help is appreciated.

Thanks,

Sarfaraz

    Hi,

    Please see this link on Ethernet triage. While this is for a different interface the concepts apply here. Please attach the results (not cut and paste) of what is asked for here. The first debug is to verify the ethernet links are up and then follow the packet path to the link partner and back.

    Best Regards,

    Schuyler
