TinyGo Not Working with pico2w RP2350 Chip

[ZeyTroX-exe]

I'm trying to use TinyGo on a pico2w with the RP2350 chip, and I'm encountering issues. I've followed all the correct installation steps, including setting up TinyGo, but the program does not run correctly on the hardware. Below are the steps I've followed and the issues I'm facing.

Installed TinyGo following the official installation guide for my platform.

Installed dependencies and made sure the target is set correctly.

Tried flashing the program with the command:

tinygo flash -target=pico2-w main.go

package main

import (
	"machine"
	"time"
)

func main() {
	led := machine.LED
	led.Configure(machine.PinConfig{Mode: machine.PinOutput})
	for {
		led.High()
		time.Sleep(time.Second / 2)

		led.Low()
		time.Sleep(time.Second / 2)
	}
}

Program does not execute as expected, the onboard LED on the Pico2w does not blink, and there is no serial output for debug information.

Not sure about the LED, but to see output from println() statements, run with tinygo flash -monitor -target=pico2-w main.go

The led on the pico2 W is not wired to the same pin as on the pico2, it is wired to the wireless chip.

As far as I know you need to use the examples from this repository
https://github.com/soypat/cyw43439

examples/blinky worked on my pico2-w

this package contains drivers / programs and examples that deal specifically with the cyw43439 bluetooth/wifi chip of the pico-w and pico2-w

@ZeyTroX-exe I can confirm that blinky.go makes the LED blink via the CYW chip's own GPIO pins, which are separate from the GPIOs of the RP2350 chip, as pointed out by @SnapshotCiTy .

Also, look for the "WL_GPIO0" (in red, prefix "WL_" for WireLess) in the schematic drawing of the Pico 2W.
