Hello
I am working on a camera sensor driver on Jetson TK1 board running linux kernel l4t 21.5.
Camera streaming works properly initially when opening the application. When the application is closed with lower exposure level and restarted either in the same or different resolution, syncpt timeout error occurs. Once the timeout error occurs, the issue persists even if the application is closed and opened with higher exposure levels.
Application works properly again only when camera sensor driver and tegra_camera driver is unloaded and reloaded. The same issue repeats if the application is closed after lowering the exposure levels.
The only factor I could think of during lower exposure levels is increase in fps. Could anyone let me know the cause of this issue ?
Note: The same camera sensor driver works fine on l4t 21.4 without the above mentioned issue
The syncpt error log is:
