JPEG - MDMA Write/Read Transfer Error

[qbaj]

Hi,

I have error (Write/Read Transfer Error) when I'm using JPEG decoder via DMA

HAL_JPEG_Decode_DMA(hjpeg ,(uint8_t *)JPEGSourceAddress ,CHUNK_SIZE_IN ,(uint8_t *)FrameBufferAddress ,CHUNK_SIZE_OUT);

I don't get any interrupts from JPEG but from MDMA I get Transfer Error Interrupt:

- mdma_jpeg_in I get HAL_MDMA_ERROR_WRITE_XFER

hdma->Instance.CISR = 0x1
hdma->Instance.CESR = 0xC0
hdma->Instance.CSAR = 0x30000400
hdma->Instance.CDAR = 0x52003040

- mdma_jpeg_out I get HAL_MDMA_ERROR_READ_XFER

hdma->Instance.CISR = 0x1
hdma->Instance.CESR = 0x44
hdma->Instance.CSAR = 0x52003044
hdma->Instance.CDAR = 0x70119800

JPEGSourceAddress (0x30000400) in RAM_D2

FrameBufferAddress (0x70119800) in SD_RAM

HAL_JPEG_MspInit is copied from examples

            Error_Handler();
        }

Why MDMA has no access to JPEG registers?
