Thanks for looking at this @luismarques We had planned to put more effort into this patch, but time got in the way for quite a lot, but I'm glad it's working; thanks for the rebase I'll update this to match shortly. And it's good that it looks like it's mostly working. I'm curious about your backtrace showing one frame, is that something without debug information, since the example I was using when writing this did show a backtrace back to main? It would be good to understand why that disn't produce the expected output.

As for next steps, if we're happy with the state then I think this should land (assuming qemu is sufficient given it is public), and then we can flesh out other bits which give a better experience. I'm not sure how to connect this to any automated testing, or where to document any way of checking this manually, the state of that isn't quite clear, so any clarity there helps.

Beyond this I think the next stage is implementing the parts for calling functions within a target, which if you could help with that would be great. I see that as a follow up patch to this, I don't see the two necessarily having to land together, since this part enables a useful debugging experience already.
