How to do code coverage on embedded

Question

I write a project for a non POSIX embedded system so I cannot use gcc option --coverage (i don\'t have read or write). What else can I do to produce gcov like output. I do have

Answer 1

Our family of C/C++ test coverage tools instrument the source code, producing a program you compile with you embedded compiler, that will collect test coverage data into a "small" data structure added to the program. This works with various dialects including ANSI, GCC, Microsoft and GreenHills.

You have to export that data structure from the embedded execution context to a file on a PC; this is often easy to do with a spare serial or parallel port and a small bit of custom code specific to your port. The tools will provide test coverage views and summaries with that resulting files.

So, you can use these tools to collect test coverage data from your embedded system, in most practical circumstances.
