Fail to run test: Unexpected semihosting command

[xgroleau]

I'm having some issues using embedded test while trying to migrate away from defmt_test. It does seem to be an issue with probe-rs library not recognizing the semi-hosting commands so it might be more relevant to the probe-rs repo, but all other probe-rs functionalities works properly.

This is using the jlink base as probe.

Here is all the relevant information

Thank you @xgroleau for reporting this.

Can you quickly try with probe-rs master? This could be a duplicate of #34 which will be fixed as soon as the next probe-rs version is released.

[xgroleau]

Thanks for the quick response @t-moe. Yes I confirm it works using master! It's probably the same issue since it looks very similar. I'll let you decide if you want to close this issue or wait for the release before closing this
