Hello every body
I have problem in using the IOWR function in my code; the problem is my code doesnot work when I write on base address 0 in my hardware as: IOWR(AES_0_BASE,0,0); // doesnot work but it work if i changed the base address to 32 as IOWR(AES_0_BASE,32,0); // work proberly however it also didnot work if i use :# define Cipherkey2_BASE AES_0_BASE+32 and i canot write on this base address as follow IOWR(Cipherkey2_BASE,32,0); // doesnot work what is the problem.Link Copied

At a guess the address offset is sometimes multipled by 4.
The last line you are also trying to add the offset twice. Personally i don't think the Altera IOWRxxx() do anything other than hide what is going on. I also suspect you want to do 32bit accesses, I thought there was an IOWR32().![](/skins/images/45C6C2D737ED71F4C51F0145C8CB1E9C/responsive_peak/images/icon_anonymous_message.png)
