Good progress 👍
In next iteration it would be a good idea to encapsulate some of those lengthy bash into some .bash files and functions?
Eventually they could be also run locally, and the workflow file gets shorten and only handling runner matrix and stages control.

Great 😍 I don't have much to comment on. Just like juan said, maybe have a local bash file would be nice

Maybe a open topic for next iteration
Now the connected tests on the XMC4700 fails. It still pass in CICD. How do we check the report.json and returns the test results?
