Problem Access DDR0

Former Member

Hello all,

I need to access the Zedboard's DDR0 memory using Linux application. However, I get fault segmentation error which means that I do not have access to my memory. Does anybody has faced the same problem and knows a possible solution?

    Hello,
    I have an IP core which needs the physical address to access the data from ram and perform operation on it.
    using mmap i can successfully write on the registers of ipcore.
    but i need to write the physical address on the registers of ipcore.
    I used malloc to create buffer A in user space now all i need to do is to find the physical address of A.
    Is there any one who can guide me?
