Other Parts Discussed in Thread: TMS320VC5502

Hi Everyone,

I am using TMS320VC5502 DSP and working on DMA1.

DMA1 configuration:

Event: External Interrupt 0

Sync: Element Synchronization

Problem facing: First 16 words I will get the same data ie which is present in the first location(0x01), I will get same 0x01 in 16 locations which is not supposed to be obtained and next words I am getting correctly.

Data and Sync events are correct since I checked it in the scope. Please help me in solving this issue.

I have attached the code with this post.

 

Thanks & Regards,
