I'm working with the latest release of WinAvr and AVRStudio 3.56 under Win98, and my target is ATmega103. My project contains some .s assembler source. The problem is that when I open the .cof file in AVRStudio I can't trace into the assembler source and watching if it works good or not. It just steps over the routine which is in the .s file. What can I do?
