Where can I find documentation on UART connection procedure on Jetson TX2?

I’m trying to connect Jetson TX2 to MCU(STM32c8t6) by using UART. But i don’t have any relevant documents. I have searched for a long time but no results, can anyone help me?
Thank you so much.

hello daohieudaica,

you may using 40-pin expansion header. please refer to NVIDIA Jetson TX2 J21 Header Pinout - JetsonHacks.
please see-also Jetson TX2 Series OEM Product Design Guide, please check [13.3 UART] chapter for using UART signals.
