Resolved! STM32H7 JPEG encoding with DMA leaves empty space

I am encoding a 200x300 image using the JPEG codec available in the STM32H743. The input format is ARGB8888, with the input buffer having a size of 240000 bytes (200*300*4). As I do not know what the output size of the JPEG codec will be , I have all...

How to Reset an UART after an error
