I've setup MIBSPI - to DMA transfer, N elements in frame (== num of MIBSPI buffers , across all my groups), to trigger once all groups complete, but with MIBSPI DMA number of buffers = N thus it keeps feeding them one by one once they all ready (been read by SPI). ( I don't see how else, as number of total bytes is larger than single DMA read )
I want M such frames, before doing anything with them. So I've setup M frames into 1 block transfer for DMA channel. BUT.
How do I reset the source address ( = which MIBSPI buffer 0 always, when MIBSPI completes all groups, my src is buffer 0), after each frame? I need to reset because after my frame completes, I need to re-start from MIBSPI buffer 0, at the same time I cannot use ADDR_FIXED for source, as I'm reading them one-by-one when request is triggered.
