Hi,

MCU is LPC1788.

I am using the DAC together with DMA ch1 to play sounds, must of the time, it works, but sometimes it stops working, the error is hard to reproduce, and I have not yet been able to reproduce very often.

The DMA transfer does not end, and when the error happens, even thoug I init the DMA channel again, it does not start.

The source for the DMA is external flash.

Any one out there using the DAC together with the DMA?

Best regards,

Frank Andersen
