This is really perplexing me. I'm trying to use a DS3231 RTC, get NTP time, go to sleep. Eventually I'd like to use the RTC to wake up the Pico, but I'm not there yet. Instead, I can't even get this basic code to run on a battery.
Running over USB while connected to Thonny: Success
Running with a CR123A plugged into VSYS/Ground: Fail
Running with USB cable plugged into a wall charger: Fail
I don't understand why it only works while running through Thonny.
I've tried switching boards, doing a flash nuke and starting from scratch, but no luck.
By "fail", I mean that it gets to the spot in the code section here before blinking the LED for an OSError:
