Since three days I’m looking an answer in this forum, but nothing worked, so I open this topic.
I’m using the Jetson TX2, with the board LI-TX1-CB, which I try to connect to a flight controller (Pixhawk) by TTL/UART provided by the J17 port (4 pins).
I doubled/tripled check the wiring, RX->TX, and TX->RX, GND->GND, from both controller. Besides, all the baudrates are set (115200 in this case). Both are using 3.3V TTL.
The pixhawk by itself worked already with a Raspberry Pi, or another PC, when I run the mavlink protocol communication.
But with the same wiring, impossible to make it work with the Jetson. I tried to make a simple communication with an FTDI cable to a PC, but no result too.
I’m using the port /dev/ttyTHS2 (which is linked to J17 as I understood). I already tried other port like /dev/ttyTHS* or /dev/S*, in case of.
The Jetson version is : R28.2.1 (From Date Thu May 2018). From what I read, this version is supposed to make the J17 work properly.
Is anyone had the same problem ? If so, I would appreciate some ideas to unlock the situation !
Thanks for the reading,
For the wiring, you can check the board here.
