assuming that you are using the ide to build a hal based project, then you can get the information by selecting: window->preferences->nios ii and then ticking the "generate objdump file" tick box.

next time you build your project, a file will appear in the debug/release directory with the extension .objdump. amongst other things, this contains the absolute address of all available symbols.

you can also run nios2-elf-objdump from the command line to extract symbol information from any elf file.

Hi,

thanks, but it isn't what I need. I can't find variable location in *.objdump

Simple example, hello from Nios...

#include <stdio.h>
int main()
{ 
  char hello_string={"Hello from Nios II!\n"};
  int i_cnt;
  for (i_cnt=1;;i_cnt++) {
    printf("%d. %s",i_cnt , hello_string);
  }
  return 0;
}

I'm looking for i_cnt location (absolut memory address).

Which address of memory I have to read to acquire actual i_cnt value ?

I looked at nios2-elf-objdump help, but the aren't any other flags which solved it.

Symbol table doesn't provide expected information. (x51 asembler has this info in "symbol table list " )

Is there another configuration or preprocesor settings?

Thanks.

Jan
