An automatic variable doesn't have a fixed address. Your count variable is

automatic -- do as svhb says to force static allocation: either use the static

keyword at function scope (in which case it will show up as i_cnt.0) or move

it to file scope (where it will show up as simply "i_cnt").

Then try using nios2-elf-nm to get your address map -- it's probably

more what you want.
