Pico2 w RP2350 CYW43 ISSUE

[equaz0r]

Cannot get wireless working with release firmware even with reflashing on new Unicorn Galactic 2350 board. Trying examples like clock.py or cheerlights with appropriate dependencies in Thonny results in [CYW43] core not in reset and HT not ready - after lots of trying i have flashed with pimoroni-pico-rp2350 v0.0.11 and whilst the display obviously does not function - the wireless works ok using cheerlights example. Discord suggests at least one other user with same new unicorn has same issue. Happy to provide any detail that helps.

(Just tried a flash from https://github.com/pimoroni/unicorn/actions/runs/12411899294 ) and same issue - using network_manager.py, WIFI_CONFIG.py and cheerlights.py example I get the below in Thonny :

%run -c $EDITOR_CONTENT
[CYW43] core not in reset
[CYW43] core not in reset
[CYW43] core not in reset
[CYW43] HT not ready
[CYW43] Failed to start CYW43
[CYW43] Failed to start CYW43
Wifi connection failed! [Errno 1] EPERM
Traceback (most recent call last):
File "", line 58, in
File "requests/init.py", line 201, in get
File "requests/init.py", line 79, in request
OSError: -6
Interestingly if I just hit run again, it locks up/no error messages and I have to reset the board to get a response.
(as per the above, the output when I ran cheerlights without the drawing function for the unicorn (commented out) and the network_manager.py example using the pico-rp2350 uf2 mentioned is :
Client None 0.0.0.0
Connecting to wifi...
Client None 0.0.0.0
Connecting to wifi...
Client None 0.0.0.0

Wifi connection successful!
(If a little slow)
So must definitely be something firmware related - will keep an eye on unicorn specific firmware for the w 2 - specific firmware I used from above that worked ok was:
pico2_w-v0.0.11-pimoroni-micropython.uf2

I'm getting similar errors from clock.py when I add the secrets.py file:

[CYW43] HT not ready
[CYW43] core not in reset
[CYW43] core not in reset
[CYW43] core not in reset
[CYW43] HT not ready
Traceback (most recent call last):
  File "<stdin>", line 215, in <module>
  File "<stdin>", line 123, in sync_time
OSError: [Errno 1] EPERM

It looks like the Pico 2 version was rushed out in time for Christmas before the firmware was working fully. I would have been happy with a fully working Pico 1 version if they had still been available.

I'm also experiencing the same issue. Interestingly, yesterday, after a few attempts of flashing 1.24.0 I was able to get WiFi working consistently having previously received the same errors as everyone else, but today I'm back to receiving the various CYW43 messages.
