I was working on something with a different board, so I used the same test setup and sketch to power it ON for the first time. Its fails in every sketch when
is called.esp_camera_fb_get()()
I tried a different lens with the same result. I tried the lens on another board and it work normally. I also tried with a different power supply, making sure all connection were ok.
This board doesn't show any problem when running other sketches that don't use the lens, like Wifiscan or test PSRAM.
As an example, the following sketch capture and saves a photo to spiffs on every other board I have but this one. The OV2640 seems to be properly initialized, as no error pops up. Also, I tried and i2c scanner sketch and it detected the lens module.
I'm using Arduino 1.8.13 and the latest ESP32 2.0.11
