Hi,
I was wondering if there is a way to turn off and on the CSI with Jetson Nano running continously. Something like a power switch which can only turn on or off the CSI. Is it possible in Jetson Nano

hello shrijan.kumar,

may I know what’s your use-case? there’re power-on/off sequence that should handle by driver layer.
BTW,
there’s sysnode to control video streaming just for testing purpose, you might found below if you’re working with latest JetPack release, i.e. JetPack-4.4/l4t-r32.4.3
please refer to below commands to force stop sensor streaming.
for example,
# echo 0 > /sys/kernel/debug/camera-video0/streaming

Thanks for your message. I will try that.
I just wanted to save power. I’m using a pi camera v2. So, I was trying to take a picture and then do processing. While doing the processing on the Nano board, I wanted to cut off the power supply of the camera maybe by adding some kind of relay or switch to the CSI.
