Description

It's really annoying when a panic happens and you can't see the output, this also allows logging to be intermingled when testing, which will be very useful when debugging tests. The backtrace output via defmt though is really not that great, but at the very least a message is displayed.

Testing

Run the HIL suite locally.

One cool thing here is that it is actually possible to mix async and sync tests! Not super useful, but in the case of GPIO where they it can be used in async and blocking it makes sense.

[MabezDev]

Drafting until esp-rs/esp-pacs#221 as it will fail in the HIL stage.

Just a couple little nitpicks but otherwise LGTM

[jessebraham]

Thanks for making those changes!

@SergioGasquez should we just try re-running the tests when this happens, or what is the best course of action?

[jessebraham]

Seems to be working in my PR, so let's try again...

[MabezDev]

I think this might actually be an issue, will investigate.

Yeah so @bugadani already warned me about this, and then I subsequently forgot 😅. The last pin, pin 30 (31) is used for flash, for chips with embedded flash. When we change the pin operation, we break that and then the program goes nuts.

I'm not sure how we test this without breaking functionality, any ideas?

If there isn't a good way to do this, we can drop that test for now, there are still some good changes in here regardless.

[MabezDev]

Eh, I just simplified the test. Add a changelog for the GPIO API too.

LGTM! Also, I will update all the VMs to use the latest probe-rs as C6 has an older revision.

Thanks! In this case the corrupted control block was a real error that HIL caught 💪, but would be good to be running the latest code.
