TDA4VM: A72 9G network does not work --- the virtual NIC (j721e-cpsw-virt-mac) is not created, and the CPSW9G on R5F is not initialized

Part Number: TDA4VM

Hello export,

We customized the hardware board based on tda4vm, and under normal conditions, A72 communicates normally with the main domain R5F network, and A72 can ping R5F multi-core. At present, we are doing DV test and find that sometimes after power-on startup, the A72 network is not connected, the j721e-cpsw-virt-mac virtual network card is not created successfully, and the CPSW9G is not initialized successfully. R5F2_1, R5F3_0, R5F3_1 have been sending connection requests to R5F2_0 and have never received a reply.
Please how to check this problem?
