I am writing software for an Arduino Zero and using vmicro to debug (EDBG) it. My project consists of roughly 10 .ino files and a few .h header files. The code does build, upload and run. When debugging, however, I see source code only for core files, but not for my project files. As recent as last week, however, the ino source files were concatenated to a single .cpp file when I built my project. This cpp source could be stepped through. For some reason, the .cpp version of my code is no longer being displayed (or perhaps not being built). Without visible source, it is not possible to meaningfully debug. So... what steps are needed to restore the .cpp version of my code that is required for proper debugging? Thanks in advance for your thoughts!
