yes, I connected via IMU harness connector. Device that I have connected is custom. I was able to see and use the device without any issues when I connected it to USB port through UART <-> USB converter. Since the number of USB ports is very limited and I’d like to reserve these for USB devices, I want to cut out the middle-man (UART-USB converter) and connect the device directly via UART.
Device is constantly streaming bytes (so it’s really easy to detect if stream is coming in or not).
I see that there are few more UART connection options (xavier-A (we use A only currently), MCU, IMU (what I tried)). I haven’t tried Xavier-A or MCU connectors (pin-out appears to be the same).
Could you confirm whether additional configuration is required to use UART?
