I'm with same issue... I've a esp32cam (I think that it's a AI TINKER clone) and got the same error code. I noticed too that the camera is very hot when esp is on :(

Did you solved this problem?

I'm trying to re-initialize the OV cam of AI-Thinker board after deep sleep wakeup, but I'm not able to initialize with camera probe error. I also tried to invoke an ESP.restart after wake up, but the only way to initialize the camera is an hardware reset ( and I didn't understand, because hardware reset did not reset camera because camera reset pin is always pulled up ). Any suggestion? thks!

check this out: https://github.com/gin66/ESP32_projects/blob/master/prj_05_heizung/src/main.cpp

1., do not let the camera driver power down the module.

  1. power on the module before camera init
  2. retry several times with power down/on, if init fails
  3. entering deep sleep: ensure camera/board/camera module power line pull downs/ups set appropriately
