TX2 HSIO/PCIe x4 lane reversal


I would like to use the lane reversal feature on the HSIO/PCIe x4 port of the TX2 module.

According to the USB Lane Mapping table I’m using configuration #1 which is x4 + x1 (ODMDATA=0x900000).

So, in the TRM, x4 lane port supports lane reversal but I couldn’t find anything to enable it. How can I enable/configure this feature?

I would need to reverse all the x4 lanes.

Thanks in advance.

Driver should be able to handle it by itself. There is no extra configuration needed.
