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?

    Hi Zaglikosh,

    Can you please show a snippet of code where you are trying to access memory?

    If you malloc() a piece of memory, you should be able to access the memory without problems if it is successfully allocated for you.  If you are just picking a pointer into memory at random and trying to access that memory space by de-referencing the pointer and you get a segmentation fault, then you are likely trying to access a piece of virtual memory that has not been allocated for you.

    Regards,
