• Damn - sorry - I always forget about this. The Web IDE expects and image that includes the bootloader - and the image I posted didn't.

    I've just padded it out as:

    http://www.espruino.com/tmp/espruino_1v85.139_pico_1r3_bootloader.bin
    

    Strange about the extra character - I think it's a bug in the forum's syntax highlighting code (IIRC it's a special 'break here' character). I had to change the Web IDE so that it ignored it in pasted code - it obviously doesn't do the same with URLs :)

  • Sorry, @Gordon, no luck with espruino_1v8­5.139_pico_1r3_bootloader.bin either. Same result: red LED stays on.

    Any ideas? I don't think my Pico is busted, because I just flashed it back with the regular firmware, and works fine.
