Good afternoon, In I have two projects Your JPEG_DecodingFs_DMA and mine. In your project, after executing the HAL_JPEG_Decode_DMA function in normal mode, the function returns 4110 bytes of Context in a stepwise 14 bytes. In my program, the HAL_JPEG_Decode_DMA function always returns 14 bytes. What settings are responsible for setting HAL_JPEG_Decode_DMA()? Sincerely, Alexander.

Hello @Vlaty.1​ ,

Have a look at this AN4996 Application note Hardware JPEG codec peripheral in STM32F76/77xxx and STM32H743/53/45/55/47/57/50/A3/B3/B0xx microcontrollers.

This application note will help you on the JPEG settings for JPEG decoding applications.

Hope this helps you!
