Hello, I've been using a SAM3U-EK for a few weeks for an audio application. When the processor is running I can see my waveform output correctly on a 'scope. That's fine. However, when using the SAM-ICE I've noticed that resets leave the DMA engine going. I suspect that the boot loader is using the RAM that the DMA is overwriting. How do I get the DMA engine to be reset via the ASM-ICE? Thanks.. Gary |
