boards: arm: rpi_pico_w: LED missing from devicetree

[mytechnotalent]

Describe the bug

I have attempted to build Zephyr within Kali Linux on an x64-based architecture as well as a Debian Raspberry Pi 5 OS as well as Windows x64. I have attempted to build the blinky project and I get the exact error each time.

Environment
1)x64 Kali Linux
2)ARM64 RP5
3)x64 Windows

Hi @mytechnotalent! We appreciate you submitting your first issue for our open-source project. 🌟

Even though I'm a bot, I can assure you that the whole community is genuinely grateful for your time and effort. 🤖💙

[thedjnK]

This board does not have an LED on it, therefore blinky will not compile because of the lack of an LED. You need to add an overlay to designate an LED

[mytechnotalent]

@thedjnK the PicoW does in-fact have an onboard LED on PIN25 so not sure what you mean.

[thedjnK]

So it does

[yonsch]

The Pico W does have an LED, but it's not connected to the RP2040 directly -it's connected to the CYW43 chip. So theoretically we can have blinky working, but only after we have a driver for the wifi chip.

[mytechnotalent]

@yonsch with the wide-adoption of the PicoW particularly with BTLE it would make sense to accommodate this port. The CYW43 is well documented and should not be a heavy lift.

[yonsch]

@mytechnotalent There's a Zephyr specific driver in the making by the chip's vendor, I can't find it at the moment

[mytechnotalent]

@yonsch do we have any idea when the PicoW port will be supported as you mentioned there is a driver in the making? Thanks again for your help and a Happy New Year! I am excited to be involved in the Zephyr Community!

[yonsch]

@mytechnotalent

do we have any idea when the PicoW port will be supported as you mentioned there is a driver in the making?

Turns out it was merged, but still without SPI support, see here: #63721 (comment)

Happy New Year! I am excited to be involved in the Zephyr Community!

Happy new year, welcome aboard :)

[mytechnotalent]

Thank you so much @yonsch I appreciate that. Is there a work around to get the Bluetooth examples working properly with the Pico W as I am unable to even get anything to compile.

[Xiretza]

Since I haven't seen it mentioned here yet, this is blocked by #67092.
