Hi, we have been experimenting for a while, with various devicetree and config changes - to make use of the third UART on the Xavier NX. Ideally we want to add an additional serial peripheral (a STM32 microcontroller) on this port, and do reliable bidirectional comms with it. We have LIDAR and oth…

hello pete28, we have not verify disable combined uart use-case. please see-also Jetson Xavier NX Product Design Guide for [Figure 12-5. UART Connections]. you may try using other port.
