PixelFormat.JPEG not working on ESP-S3 CAM

[maschhoff]

ESP Crashes if I try to run PixelFormat.JPEG on a Freenove ESP32-S3 WROOM CAM using your latest S3 firmware with PRAM.
greyscale works but I cannot deal with it.

Thank you!

I have also a freenove and didn't had problems so far.

Please try the following:

• Use te freenove firmware (so you don't need to specify the pins)
• You can pass the Pixelformat argument on construction, so you don't need to reconfigure
• You don't need to initialize (this happens at construction, as long as you don't pass the init flag with false).

Hey @cnadler86 Thank you so much, I was a bit too fast choosing the firmware - with FREENOVE firmware it works so great.
Thank you so much for this great work I can now build on!

I am implementing a very small smart meter AI MQTT bridge
