AM6442: TMDS64EVM failed to found the PHY Dp83869

Hi,

Just to confirm, you are using the TMDS64EVM without any modifications to the phys on the board? If so, did you check that loading the EtherCAT Slave Simple Demo works out-of-the-box, without any modifications to the source code? With the TMDS64EVM you should see output similar to the following. For some reason on your output log, there are some differences in the "PhyAddr" and phy reset numbers.

If loading the out-of-the-box EtherCAT Slave Simple Demo (without any code modifications) still result in the issues you are seeing, based on the output log, it seems like the mdio bus is not able to connect with the phys. Are you able to measure the MDIO clock and data lines with an O-scope/logic analyzer? 

Another check is to check the LEDs on the RJ45 connectors you are using to connect ethernet cables for your setup. Is the green LED lit up when the board is connected to another board/PC/switch? This is to make sure that a link can be detected but doesn't necessarily mean that the phys are in a good state or that the MAC is able to communicate with the phys via mdio.

Best regards,

Daolin
