Not able to blink the onboard led on rpi pico w
I'm trying to get started with running rust on my newly purchased rpi pico w ( with wifi support ). Initially when I set everything up and run the blinky example, it did not work. I then ran the micro python example and the led was working. For the w version the rpi community says that there is a slight change in the way onboard led is configured

Is there any change that must be made in the rust blinky example to get it working?
"a slight change" is an understatement: The LED is connected to a different chip, the wifi one, not the RP2040. Therefore, to blink the LED, you need a wifi driver. Which is not yet available in the released version of rp2040-hal.
If you are adventurous, you could try the experimental WIP version at https://github.com/jannic/rp-hal/tree/pico-w. The blinky example is at https://github.com/jannic/rp-hal/blob/pico-w/boards/rp-pico-w/examples/pico_w_blinky.rs
(BTW, please don't close this ticket. There have been multiple instances of the same question in the past. Perhaps an open ticket with a descriptive title will help other people with the same issue.)
Is the pico-w branch going to be merged into main at some stage? I see it's behind main by about 6 months? Anything others could do to assist with it?
In theory, that's the idea. In practice, it was blocked on some other crates which were not released to crates.io yet, and would probably need nightly rust.
I didn't follow recent developments closely so I'm not sure if the reasons still exist. My plan is to revisit the situation every now and then, but I don't want to spend much time on updating the branch until it is realistic to actually merge it.
