arduino: can't step line by line in proteus

[gabriel]

Hello:
a long time ago, using arduino 1.6.7, when debugging in proteus (the .elf file), I was able to step line by line (I saw the address of each line code).
Now using ver 1.8.12, I can't (I just have ---- instead of the address of line code).
is there a setting that allow that?

Thank you

I thought you have to use the *.cof file not the *.elf file.

It will work with a .elf but you need to edit the source code from within Proteus.  Search YouTube for the follow Proteus Tutorial : Proteus VSM for Arduino. Its a little out dated but the conceptes are still the same.
