Hello,
I have made all the necessary modifications to the firmware code to make it work with the ESP32 CAM board. I was able to connect the board to the daemon CLI and acquire some samples, but then it stopped working after a few samples. The error was:

The board could not recover from this error unless I hard reset the device. Here’s the same error I encountered after re-opening the daemon CLI.
