Hi Thormodo,
Hmmm.. but the codes that I tried worked. As you can see in my 1st message, I was able to write that string using the standard IOWR. I did not put a "(int)" before the string though. When I read it and printed it out it was successfully printed.

Didn't you get some warnings then? If I use the syntax below it get the following warning:
warning: format argument is not a pointer (arg 2)
IOWR_32DIRECT(ALTMEMDDR_1_BASE, 0x3fe, (
int)"THIS IS TO TEST HOW MUCH DATA CAN A MEMORY SPACE CONTAIN");
printf("%s\n", IORD_32DIRECT(ALTMEMDDR_1_BASE, 0x3fe));
printf("%s\n", IORD_32DIRECT(ALTMEMDDR_1_BASE, 0x3ff));
And it prints out (without crashing)
THIS IS TO TEST HOW MUCH DATA CAN A MEMORY SPACE CONTAIN
THIS IS TO TEST HOW MUCH DATA CAN A MEMORY SPACE CONTAIN
Maybe it's doing something funny with cache memory, I really don't know since I never used strings with NIOS II before.
