Hi,
I have a problem with configuring priorities for DMA channels and LTDC controller.I am using a DMA channel to communicate with a DSP processor. In this channel I need a large data transfer. When I start the DMA channel, I get a FIFO Underrun error from the LTDC controller, and the screen blinks very much.How to set up the priorities of DMA channels? I think that priority for LTDC shoud be the highest, but how can i do it ?Regards
