I got a Jetson TX1 that I recently flashed using Jetpack L4T 2.1 linux x64 and post flash installed CUDA and the OpenCV 4 tegra
Then I installed ROS indigo, the ZED driver and successfully compiled the ZED ROS wrapper.
I am able to lock up (freeze) the Jetson TX1 almost instantly as follows:
In terminal 1 => roslaunch zed_wrapper zed.launch In terminal 2 => rqt_image_view
In terminal 3 => $ rostopic echo /camera/point_cloud/cloud > cloud.txt, give it a minute and it locks up the JTX1.
At first I thought that perhaps with the high data rate and all, saving the data in a file was the culprit. However, when I don’t perform the third step (i.e. I just launch the zed_wrapper in one terminal and the rqt_image_view in another), it runs fine for about an hour and then the JTX1 becomes unresponsive again.
I first thought that this might be an overheating issue, but when I logged the temperatures using Psensor, I am not going over 50 degrees centigrade for both CPU and GPU. As a matter of fact, the last time the JTX1 became unresponsive I was only at 44 degrees C for the CPU and GPU. In all cases the fan was running. My CPU runs at 33 degree centigrade when it idles.
I get similar results if I am not running rqt_image_view, but for example print out the cloud point topic (i.e. $ rostopic echo /camera/point_cloud/cloud).
I once had the JTX1 freeze up when I was running the ZED Depth Viewer in /usr/local/zed/tools but I am currently have been running this tool for over three hours now without locking up: both the CPU and GPU are at a steady 50 degree C.
Has anyone else had similar experiences?
