intr clash between NDK and EDMA

           Thanks for your reply.

           My program consists of two parts. The first one is to calculate, in which I use EDMA3. The Second one is net. I know for C6747, there is a conflict between EDMA3 and NDK. So accoring to http://processors.wiki.ti.com/index.php/Network_Developers_Kit_FAQ , I modify RXINT=5 and TXINT=6 for NDK.

           The above problem about EDMA3 halt at while(irqRaised1==0) is happened after I modify RXINT and TXINT.  If I only use the calculation codes, EDMA3 works well. So I think maybe there is still  conflict between EDMA3 and NDK.

    2 questions from an observer:

    1) Why are you coding a for-loop on Ccount when it's included in the PaRAM set?

    2) You start by initializing all the paramSet fields to 0 and then use paramSet.opt &= 0xFFFFFFC -- this only guarantees that the 2 lowest bits are 0 whereas all other bits are just what they were before (set to 0). Is this what you intended to do?
