Please describe your issue below:
I can’t use camera after moving to suspend mode.
How to reproduce:
Open camera app
Enable suspend mode for more then 60 seconds
Disable suspend mode.
Camera will show black screen.
Notes:
After enable suspend mode by pressing power button I’m waiting for 50-60 seconds. After moving to suspend mode my board have power 3.5W. After 50-60 seconds board power drops to 0.6W. When I’m moving out from suspend mode (when I got 0.6W) camera doesn’t turn on.
@Y2Kot But I think your camera application applies for a lock to prevent the system from entering deep sleep. This method is better. You can refer to this linked document. https://www.51sjk.com/b36b282198/
@Y2Kot I’ll replace your code and take effect. The system has not entered deep sleep. That’s probably because your compilation didn’t take effect. So is it because you didn’t compile the kernel? Please post the complete compilation process.
