I've been lurking as you have been making progress. Now you have crossed
into something you probably need some hints at. Some things to check:
+ Obviously, check output for signs that something didn't happen right.
Anything from a path wrong, etc. The configuration has to be right to
point to the source code, object code, executables, etc.
+ A lot of source code has moved around since last summer. Check
that it is looking in the right places inside RTEMS.
+ Does the mechanism to get debug information actually work? Cillian?
+ There is a utility named trace-converter. Make sure your qemu traces
have information in them.
+ Cillian probably has guidance on running it just on one test (say ticker)
so you can see every step.
+ Check that the executables have symbolic information. "file" should
show if they are stripped or not.
I recall covoar has a verbose mode which should be of use.
Cillian .. do you have instructions on running covoar in gdb?
