i.MX8MQ PCIe Tx and Rx Swapping

Hi NXP Team,

We are working for communication between two i.MX8MQ processors using the PCIe link. For the same, we are planning to do below connections from the hardware.

To support the above connections we are required to swap the Tx and Rx lines of one port of PCIe.

In the i.MX8MQ Processor is there any configuration available where we can swap the TX and RX signals on the pins? (Similar to what is being supported for the UART Tx/Rx swapping?) 

Regards.

Hi Harshit

I am afraid it is not supported in hardware, sorry.

Best regards
