circuitpython: RPI pico W is not always detected as disk in Windows 10
CircuitPython version
Adafruit CircuitPython 8.0.0-beta.3 on 2022-10-20; Raspberry Pi Pico W with rp2040
Code/REPL
import time
import board
import digitalio
led = digitalio.DigitalInOut(board.LED)
led.direction = digitalio.Direction.OUTPUT
while True:
print("test")
led.value = not led.value
time.sleep(1)
Behavior
Board is not always detected as disk in windows 10.
Description
- Boot works always fine, and circuit python disk is always detected after UF2 flashing reset.
- After disconnect / turn off, the board is not detected as disk in most cases
- I wrote blink script and powered board from phone charger and program runs / blink only 1 of 5-8 tries
- I was thinking about possible faulty hardware, so I flashed
Adafruit CircuitPython 7.3.1 on 2022-06-22; Raspberry Pi Pico with rp2040
and windows always detects it as circuit python disk

- move cyw43 init after safe mode check This may fix #7112, though the root cause is unclear — committed to jepler/circuitpython by jepler 2 years ago
If the analysis in that other PR (“it looks like the wireless firmware is being loaded during USB device enumeration”) is correct, I do not think they would be the same cause.
In CircuitPython, we load the firmware during
port_init
which I think is before USB enumeration can possibly occur (usb_init
is called later insupervisor_workflow_start
)
