This may be a hardware power supply issue. When the brightness of the environment decreases, the sensor requires a larger current to achieve greater gain. |

The problem is clearly software problem, see the comment above |

What is the expected behavior?
the example works in every light conditions
What is the actual behavior?
there is a watchdog reset, especially in dark environment
Steps to reproduce.
Debug Logs.
More Information.
I’ve tried the video recorder example, the code crashes in a strange way, there is a watchdog reset, but typical information (like backtrace or coredump, if enabled) is not available.
I’ve tested the S3 Eye and S3 Korvo 2 board with 3 OV2640 cameras. Always the same problem, the crashes are somehow related to light conditions, if bright, then sometimes works, but if darken (or with lens cover), then fails every time.
I’ve tried also different SD cards, clock speeds, camera resolutions, etc. No changes.
The complete source (even with managed components) attached, however the alterations from original are just adjustments for the boards I have.
