DMA between PS/DDR and PL

100prathima
100prathima over 12 years ago

I need to transfer data through DMA from PS/DDR to memory mapped custom IP(not streaming) in PL and viceversa.
I have used UG873(CTT) as reference and successfully completed CDMA in chapter 6.
But, here the source and destination both are on DDR.
Is there any way to modify the interconnections mentioned in UG873 chapter 6 to achieve DMA from PS/DDR to PL
Or, Should I follow an entirely different procedure?
Please let me know the right way to do it.

    what do you mean by "not streaming"?
    Did you find out any solution to your problem? I'm working on the same thing at now

    you can access PS/DDR Signals by the PL since they have pin locations but i first will have a look at the documentation you mentionned

    By saying "not streaming" I mean that I need to access some addressable locations in PL.
    I am able to access the memory but I need to do it using DMA. I'm not successful yet.
