This probably means wireless is hosed in general. My money is on 74fb42a. Just cherry-picking that on to v1.23.0 to confirm.

Edit: I was wrong. Next commit 😆

Edit2: Okay I cherry-picked 83e82c5 onto v1.23.0 along with the previous mentioned commit, and that's when breaky breaky happens.

So v1.23.0 + 74fb42a + 83e82c5 = Borken.

Confirmed that the actual master branch shows this behavior, but version 1.23.0 is fine. So something broke in the communication between the RP2040 and the CYW43. At Pico W, the LED is conncted to the CYW43 module.

P.S.: Accordingly WIFi fails as well.

I’ve had reports that stuff as simple as “time.sleep” is broken but I’ve not been able to replicate.

I may have included the offending commits in our v1.23.0 custom release in an attempt to get my pins.csv fix 😭 but I’ve sorted that now.

Thanks for the report. I can confirm the issue. See #15222 for a fix/workaround.
