MCU-PLUS-SDK-AM243X: PROFINET Frame Transmission Issue on Custom Board with KSZ9031RNX Ethernet IC

Tool/software:

Hi Expert,

We are working on a PROFINET project using the MCU-PLUS-SDK-AM243X, version 08_03_00_18. The code works perfectly on the EVM board. On our custom board, we are using the KSZ9031RNX Ethernet IC, which we have successfully integrated. To test the Ethernet IC, we used the PRP example.

For testing PROFINET, we are using the following setup:

For the IO controller, we are using a Raspberry Pi with CODESYS. This setup works perfectly on the EVM board.

However, when we run PROFINET on our custom board, it fails to send frames, even though the initialization completes successfully. The following log is shown in CCS:
