Cube orange serial rate issue

Hi all,

I am connecting a jetson nano to a cube orange via the nano GPIO pins and having major issues with any baud rate above 115200.

Mavros connects no problem to a CubeBlue with baud rates of 921600 but a CubeOrange will encounter serious issues with baud rates above 115200. Is the H7 doing something differently with these serial lines that would cause problems? Are there settings I am missing for the serial interface?

This was tested on arduplane master. Any info would be great as to a fix.

@Michael_Oborne Philip said you might have some insight into this?
