My initial thought was about GPIO12, which is the flash voltage bootstrapping pin. GPIO13 is not a bootstrapping pin and should be unused by PSRAM. Really odd that it causes...

Such long wires between camera and ESP are guaranteed to not work. Please try OV7725 in BMP (RGB) mode first. You will see the stream.

Connect OV7725 camera, then in app_main.c change `CAMERA_PIXEL_FORMAT`: ``` #define CAMERA_PIXEL_FORMAT CAMERA_PF_RGB565 ```

I don't have plans for adding support for ov9650 myself, but keeping this open in case anyone else is willing to contribute this support.

I suggest trying with bitmap mode first. See if you get reasonable and stable image. The issue in JPEG mode might be caused by data corruption. It is easier to...

You are right, i think the value does not matter when I2S is writing data into the buffer. It would have mattered if I2S was reading data from the buffer....

> Is the ESP32 Technical Reference Manual as it relates to I2S Camera DMA considered complete? I wouldn't be able to write this driver if all I had was the...

Thanks for reporting this. - Does this happen with the current master branch of this project? - Does this happen with latest ESP-IDF? - What type of camera and what...

Ok, would you mind testing with more recent versions of both esp32-cam-demo and esp-idf? I've been running the latest version of both, with modem sleep enabled, on OV2640 for the...

Seems like i still had `quirc` in my components directory when I was preparing the example, so didn't notice this stray reference. I suppose it can be removed for now....
