Running "spike bbl" command freezing in the current build about riscv-linux

This is usually a version mismatch between Spike and Linux. Can you try the versions tagged on the "new" branch of github.com/sifive/freedom-u-sdk?

Thanks for the reply Palmer. I will try and let you know.

There's a coherent set of versions tagged in freedom-u-sdk, if that doesn't work then feel free to re-open the bug.

this is a failure in my CI system, any tips on how one would root cause the issue? or, at the very least, get a trace, error msg, that I can use for triage?

Well, you've got the illegal instruction right there in epc. You should be able to figure out what function it's in by looking at your Linux binary, if you can upload an "riscv*-objdump -d vmlinux" then I can take a look.
