Hello everybody!
Can somebody tell me how to connect jetson TX2 with Pixhawk?
So far i’ve just wired the pixhawk 2 cube to the jetson tx2 GPIO like this:

Thank you very much!
If you choose to use ROS, there’s a package called mavros. You can directly read from the usb. I tested on my JTX2.
Hey buddy! How did you do it?
I’m running
roslaunch mavros px4.launch fcu_url:="/dev/ttyTHS2:115200" gcs_url:="udp://@127.0.0.1"
but I’m stack I got this:

So that means the connection between the PX4 and the TX2 is not done.
How can I fix it.
The TX2 is connected from UART 2 /dev/ttyTHS2 to the pixhawk telem 2
I know that it’s pretty late to reply. But I had the same issue. Getting the result above is not enough. We should get a heartbeat. If not, then it’s not really communicating.
First check the serial port with cutecom by connecting it to some PC serially (in my case, using tty to USB cable). Check if you receive the same message as you send on the other end on both sides.
In my case, there was some fault there. So I used the other UART port and everything worked fine.
