Not a bug!
I ran into the problem that I could not apply settings to one of my waveshare rp2350-one. Settings are not cleared when reflashing firmware (which is good for upgrades I guess).
However I could not get the neopixel working.
Looking for an easy way to "factory reset" I found https://learn.adafruit.com/adafruit-metro-rp2350/factory-reset-2 which did the trick for me. Thought it would be good to share this.
Thanks for taking a libre spin on this cool project!
