Regardless of any settings it is impossible to capture JPEG with the OV5640 sensor. Tried faster/slower clk speed, compression, high/low resolutions, all leads to panic crashes and/or NO-SOI, with extremely rare occurrences of a valid capture (1/100 type scenario). There is absolutely no problem capturing RGB565 frames though, this works perfectly fine. Only the JPEG capture fails,
The sensor JPEG Capture is confirmed functional and highly reliable onto a STM32H743VIT6 using the init registers below. However it is not functional using the ESP-IDF 4.4.1 and 5.0dev with the ESP32-Camera API.
