Question

STM32F767 JPEG

Hello

I'm just diving in to ST tools and MCU's.

I'm working to evaluate the jpeg encode function of subject chip on the Nucleo-144 board as a CubeMX project.

I'm unable to find a project directly for this configuration but have been trying to follow the example 

STM32CubeF7/Projects/STM32F769I_EVAL/Examples/JPEG/JPEG_EncodingFromFLASH_DMA, which doesnt apper to be a CubeMX based project.

Eventually the above code calls into

HAL_JPEG_Encod_DMA which eventually calls HAL_DMA_Sstart_IT which aborts because the handle->hdmaout.State is NOT ready and aborts.

IT looks like the DMA is not initialized?  I do not have any DMA peripheral defined for the JPEG MX function JPEG, I dont have any Middleware defined for LIBJPEG

What am i missing?
