How to connect my LiDAR(UART) with TX2

Hello all,

My LiDAR use UART to communicate, but I’m not pretty sure about how to connect the pin with TX2. Currently I use USB HUB to connect my 3 LiDARs, but when I run my program for few seconds, TX2 will stuck and reboot.

I tried to use J21 pin 8 and 10, where I saw UART on the TX2 developer kit, but when I connect it with my LiDAR, TX2 will stuck ant the NVIDIA logo screen and not boot. And I don’t know how to use other UART port like J17 seems like support UART.

Sorry for being a layman and thanks for your help!

Hi asyuan0506,

What’s the Jetpack version in use?

Please share the full serial console log at this moment.

You can also share the full dmesg and device tree for further check.
