• 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 :)


  • This is what dmesg reports, seems OK.

  • OK, all well, just needed to power down and then reset everything by re-inserting the PICO.

    I'm surprised I didn't get some sort of confirmation when the PICO was upgraded correctly from the Web interface?

    'I'm surprised I didn't get some sort of confirmation when the PICO was upgraded correctly from the Web interface?'

    On Dis-Connect, Re-Connect, did the 'Epsruino' banner and version display?

    Results of process.env ?

    It is also possible to view the log messages from within the WebIDE.

    From the upper right hand corner

    WebIDE >> Settings >> Console

  • Thank you! Just what I wanted to see ...

  • Glad you got it sorted! I am surprised at the lack of confirmation though. Usually when firmware is updated you should see a popup saying 'firmware update complete' or similar...
