I used TI official routine v00.04.00 to configure RMII mode and do EMAC loopback. The debugging code cannot obtain the phyid. I gave the hardware schematic diagram and the configuration in HCG. Please ask the engineer to help solve the problem. Thank you.
In the code, the value in USERACCESS0 is 0x20410000, and the phyid is 0. I don’t know why.
In the circuit schematic diagram, dp83640 is directly connected to the tms570lc4357 chip through the connector. Please help confirm whether there is a hardware problem.
This is my configuration in hcg
