I hope CI will catch it too, but it can take a while to do so, hence I'm sharing it here with you.
You can reproduce it with locally by running, for instance: `$ tests/scripts/task_python_microtvm.sh`
So, even if that works, I'm wondering how to disable it for the MPS2 board only, since CONFIG_FPU=y will be enabled by default anyway for all the boards, and apparently CONFIG_FPU=n is not enough to disable (override) it per board?
