Hi

We have five ESP_EYE development kit.

I flashed Camera_Web_Server firmware from esp-who(newly cloned) framework.

From that five boards, 4 boards are working fine and i am able to stream the video in server.

Only one board is giving error : Camera init failed with error 0x20003,

Here is my LOG :

Can you swap the sensor on that board and try again? Put one from the other working cams and see if it's the board or the sensor that is faulty (I will bet on the sensor here). Error means that the ESP was not able to communicate over I2C with the camera, but the line before that means that the camera did not start at all (timeout waiting for VSYNC).
