hello nivida team.
My current jetpack version is nvidia jetpack 5.1.5-b11.
The problem I am currently facing is that I have enabled UARTB in jetson orin nx, which is/dev/ttyTHS1, but there is a problem when using it.
After short circuiting UART2-RXD (DEBUG) and UART2-TXD (DEBUG) in J14 and using // echo “hello” | sudo tee/dev/ttyTHS1 //to write data, I did not receive any data in //sudo microcom-D/dev/ttyTHS1-b 115200//.
Testing/dev/ttyTHS1 or UARTA in the same way is normal.
How to solve this problem.
Hi 2502592176
Are you using Jetson Nano or Orin Nano? Devkit or custom board?
It is not the expected operation to me as debug UART will be used by several firmwares and you should not short them or use them for your custom use case.
Please use the UART interface from either 40-pins header or M.2 Key E.
