Now,I want to use Edma read Mcbsp's DRR.When the REVT is coming ,the EDMA complete interrupt is trigger,but the data in DRR isn't copied into the dest address.
But if i set the soures address like a array a[10]'s address,the data in a[10] can be copied into the dest address.
Is there some limite in EDMA ?
thank you.
