How do I need to configure cache validation invalidation for USB transfer to PC of continuously DMA filling buffer? Right now I have some visible errors ( I stream DCMI video via USB).

DMA1_Stream0->FCR = 0DMA configured to work in double buffer direct mode.And I get FEIF0 error interrupt flag?

I have STM32H7 DCMI + TVP5150 I want to get the frame, the only result that I get is 720 pixels and no more. My main culprit is DCMI->ESCR register, could please anyone help me? I calculate SAV EAV codes, but using them I elicit no result that differ...

I read about SAV EAV codes, but there should be 8 variation (line start, line end with and without VB for each Filed (0|1)).So there are only 4 position, how should I configure this registers for correct work with ITU-R BT.656?

What configuration is necessary for DCMI module?
