CAN bus accidentally swapped TX and RX is it possible to solve (in firmware) without board rework

[ultra12]

Dear Team,

I am interfacing an isolated can transceiver with my microcontroller. My schematic is given below.

My question can I solve this issue without any rework in the board?

May I know firmware persons can help us by doing some changes in their code and making this interface up.

Is it possible to swap MCU RX and TX in firmware

Regards

Hi @ultra12

It is not possible to swap TX and RX through SW. The only workaround would be to rework the board.

Best regards,
