Corrupted image file with esp32-s3 and OV5640 module

We have been working with the ESP32-S3 dev module (ESP32-S3-WROOM-1-N8R8) in order to capture 5 megapixel images with the Arducam OV5640D (which essentially is, to our understanding, a breakout board with voltage dividers for the OV5640 camera module)
When setting the resolution to HQVGA (240x176) we get the following output:

Sometimes the printed bytes correspond to a broken jpeg file, otherwise it is either corrupted or valid.

When setting the resolution to FRAMESIZE_QSXGA 2560x1920 we get "camera capture failed error", despite PSRAM being enabled and abundant.

Upon further testing, we have discovered that even with the higher resolution the behaviour is similar, with the output being either "camera capture failed" or a sequence of bytes containing valid jpg markers (FF D8 FF at the beginning and FF D9 at the end) that amount to an invalid image file.

Hi, can you please share your pin configuration to show how are you connecting your camera with the esp32 module. I am trying to connect a arducam 2MP plus camera to the same, but I am not able to read the frames.

Thanks
