Hi,

Are you looking for a virtual client on Linux and ETHFW on the MCU2_0 core as a server? If so, you need to update the RTOS side for configuring SerDes2 and MAC Port-5 in SGMII from the board_j721e_evm.c file and the application main file with the required ports.

If you are looking for a Native Linux solution, then you need to load non ETHFW application on MCU2_0 so the MCU2_0 core does not use CPSW9G. Update the Linux device tree for SGMII mode with SerDes2.

Additionally, refer to the FAQ for instructions on enabling CPSW9G on the TDA4VM.
