Question Regarding VDMA tripple buffer resolution

Hello,

     I am using vdma triple buffer code provided by xilinx,It's working for resolution 752*480. But i want to use it for other resolutions like 2128*16 or 4256*6384 its not working,only first buffer will be filled with data and other two buffers contains junk data. Please suggest me if there is any solution .

 

Thanks and regards

Nishith Kumar.

Re: Question Regarding VDMA tripple buffer resolution

Hi @nishith.kumar,

 

My first assumption is that your pointers to the buffers are not set correctly or that there is an issue with your size/stride registers. Can you confirm that you are setting the Start addresses correctly for each of the resolutions and/or post their values?

 

Thanks,

Sam
