I run in loop the example : luckfox_pico_rtsp_opencv

[root@luckfox root]# while true;do ./luckfox_pico_rtsp_opencv & sleep 5 ; killall luckfox_pico_rtsp_opencv ; sleep 1; done

after some loops the ubifs driver is dead :

all is ok after reboot ...

I suspect that rkmpi SDK do not release some ressources then DMA is broken ....

I am not able to do more because I have not the rkmpi sources ....


can you help me ?

Hello, it is not recommended to repeatedly release and apply for resources that need to be reused. This will place a burden on the CPU and DDR, leading to errors when synchronizing data to spinand in ubifs.
If you are looking to determine the issue with the rkmpi library, it is recommended to consult Rockchip. We were not involved in the development of the rkmpi library and we are merely its users.
