Urgent help required - DMA - padma - Jul 8 8:36:26 2008

Hi,

I am working on DM6446 simulator. I tried to do DMA transfer with the
following configurations.

Transfer Type = 2D2D
SrcElementIndex = 0
DstElementIndex = 1
ElementSize = 1
NumOfElements = 24
SrcFrameIndex = 32
DstFrameIndex = 32
waitId = -1

After these settings i have given ACPY3_start.

then ACPY3_wait()

But it is entering into infinite loop in wait. I am using CCS3.3,

If I give NumOfElements = 16 then its working.

Plz, Let me know whether my configuration settings are wrong or is it is the
bug in CCS?
