Stop I/O DMA for Blackfin
hi !
i'm looking for an option like Stop I/O DMA for my blackfin BF537 or BF607
the problem is that debugging SPORT DMA is very tricky with breakpoints if DMA contiue to run while halt on breakpoint.
i've found the Stop I/O DMA, which seems no visible or my target (ADSP-607)
How could we handle this ? SPORT channels are changed if i debug the ISR code of SPORT (use of TDM mode and 8audio channels in&out)
kind regards chris

Hi Chris,
From your mail I understand that you want to use DMA in Stop mode. Please correct if my understand is wrong. If that was the case, I would suggest you to look at the Stop mode DMA configuration. This can be enabled by setting the FLOW bit DMA Configuration register for Stop mode. For more details about programming please refer the DMA chapter in Hardware Reference Manual of ADSP-BF60x. The link for downloading the manual is given below.
