I am using the following setup within ROS environment:
- Jetson AGX Xavier Dev kit fully configured, with a battery as power supply (LiFePO4, 12V)
- Industrial PC with Ubuntu 18 connected through LAN to the Jetson
- Two Stereolabs ZED 2 cameras powered through an USB 3.0 HUB with the same power supply of the Jetson (HUB then connected to the Jetson).
Below the problem I have experienced:
Industrial PC was used as master and a Jetson Agx Xavier as slave in ROS.
Roscore launched on the master.
On the slave terminal, the zed_multi_cam launch of the zed-ros-example package was used to launch two zed 2 cameras and their respective display on RVIZ (shown via a screen connected to the HDMI connector of the Jetson). The launch file has been modified by correcting the name of the cameras, their position, and the type of cameras used (both cameras have been set as zed2, in the default settings one was set to zed2 and one zed). A few seconds after launching and viewing it on Rviz, the Jetson turns off.
All the devices are powered thought the same battery, with common GND.
What could be the problem?
Is there any way to find any log file in the Jetson to check which was the cause of the shutdown?
