RHYX-M21-45 camera boot issues

[tomu4]

I got this ESP32-S3-CAM from Aliexpress as a bundle with RHYX-M21-45 camera (according to the description, it should have been OV2640, but that's not the point). I tried loading compiled firmware, which caused bootloop. I tried compiling my own from source files, and got camera initialization error 106, as I found online, it's 0x106 - Operation or feature not supported. I therefore changed CameraConfig.pixel_format in camera.cpp from PIXFORMAT_JPEG to PIXFORMAT_RGB565. That solved the bootloop issue, I am able to load the configuration website with no problem, but it doesn't show an image, neither is the image uploaded to Prusa Connect. I suppose it's because camera's lack of JPEG support. Is there more troubleshooting I could try, or do I just have to buy original OV2640 camera with JPEG support?
