You should better consider using the IORD() and IOWR() macros from the <io.h> for accessing your IP registers, or you might experience arratic behaviours due to data cache operations and compiler optimizations.

If you have tested your component outside of the NIOS-II system (in a simulation only separate project) and the results were as expected, and you&#39;re still having problems, you could "signaltap" your entire design.
