JetsonK1 auto log out while using frame grabber


Recently I’ve been developing a vision system using FIR cam and Radar on JetsonK1 board.
Both device uses frame grabber using USB 2.0 port. However while developing, the board suddenly and constantly logs off. I’m not sure if it’s because of the frame grabber or not, it just suddenly logs off with closing every process without saving any. Actually I’m not even sure with the moment it happens. It just shuts down to log in screen anytime without any significant events.

Does anyone had similar case? or does anyone have any clue to solve this problem?

There have been some issues in the past with this, but I haven’t heard of it being an issue with R21.4, the most recent release. What version of L4T are you using? “head -n 1 /etc/nv_tegra_release” to find out.

You may also want to stop any USB autosuspend or energy saver modes. See:
