Jetson Xavier NX UART


I am trying to use Xavier NX uart0 (/dev/ttyTHS0) with my IMU device.
However, I can’t get any meaningful data from the device. Rx and Tx are connected with series 3k3 resistors to the jetson.

I managed to make the same device with same configuration work with Jetson nano.

Note: The uart0 is able to send the signals over Tx which I checked with an oscilloscope.

What can be the problem?

Best regards,

hello mertturanli ,

please access Jetson Xavier NX Product Design Guide to review the UART signal connections.
