General • Re: Pico W freezes when using PIO1 state machine 0 + CYW43

That's expected, the SDK uses that state machine by default to communicate with the CYW43 chip. And you're not using the claim* APIs, so the SDK has no idea the SM is already in use for something else, and thus loads it own code leading to a conflict.

So just claim the state machine before initializing the cyw43 driver if you need SM 0 in particular for some reason.
