Just got a new Espruino PICO for Adafruit... Thought I would update the firmware.
I'm seeing the onboard LED's flashing happily, and when I get into the flashing app all seems to be well, until right after I select the Espruino PICO as my target for upgrade.
When I select the "next" button, it just silently returns to the web IDE in Chrome with no observable effect.
Is there anything I can run from the command line to see what's happening? I have every flavor of ARM programmer available, and most ST Linux utilities installed on this Ubuntu 20.10 image, but since the boot-loader appears to be sane, I was hoping from something simple :)
Thanks!
