• Getting back to my Pico after some time and trying to update firmware using WebIDE.

    Problem: The Pico comes up on COM17 just fine with current version 1V81. This version was probably shipped with the unit when new as I don't recall doing a flash before.

    When using the flasher and selecting Pico, any bin, the message directs to unplug, hold btn, plug in for Red/Green flashing. That works so far, but when hitting NEXT the port is missing and the flash fails.

    What am I missing? Is something else needed on the Pico (i.e. a jumper or short)?

    Many thanks.

  • When you plug back in, are the LEDs on the Pico both pulsing? If so your hardware is all ok

    And I guess you're on Windows - what version?

    Is it possible the device is appearing as a different COM port? That's often the case with the bootloader since it's actually running slightly different code for the USB, so windows detects it as a different device. Maybe check out the device manager?

    If you still have trouble you could try installing the 'Non-Windows XP' drivers from http://www.espruino.com/Quick+Start+USB and see if that helps?
