  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 :
  
  
  ls -R /oem/
  /oem/:
  usr
  
  /oem/usr:
  bin etc ko lib share
  
  /oem/usr/bin:
  ls: /oem/usr/bin/rk_event_test: Input/output error
  ls: /oem/usr/bin/sample_ai_aenc: Input/output error
  ls: /oem/usr/bin/luckfox_gpio_test: Input/output error
  ls: /oem/usr/bin/simple_vi_bind_venc_chn_sharebuf_rv1106: Input/output error
  ls: /oem/usr/bin/rk_mpi_aenc_test: Input/output error
  ls: /oem/usr/bin/simple_vi_bind_venc_jpeg: Input/output error
  
  in the console :

  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 ?
