Hi,
I am using DM3725 media processor for one my Telecom project. I have come across weird situation and I want to discuss more about it.
I am using SDMA hardware synchronized transfer between SPI port and slow memory(SDRAM). The code runs on DSP. I have observed that during SDMA transfer, DSP gets locked. DSP becomes active only after SDMA transfer is done. Means after a block transfer.
Is it expected behavior? If so why is this behavior and what could be the reason? And does it happen same if I run SDMA under ARM? Means if the code runs on ARM? Or does it only happen between DSP and SDMA? Could somebody answer?
Regards
