Memory access from Nios I

Hello Fly,

I presume excalibur.h has given you an address for your block of user logic and has cast it to be a pointer to void like this na_mylogic ((void*) 0x0002010)

If your logic expects to be written and read in 32-bit wide accesses (ints) then just declare an integer pointer and make it point to your logic using a cast.

unsigned int *my_pointer = (unsigned int*)na_mylogic;

You could now use my_pointer to access your logic as if it were a memory array (of integers). You could easily modify the above to suit the width of your logic.

I hope this is what you were asking, and it is of some help.

Banx.
