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?
