PicoComA9X not booting

  • After programming the board (15cb30), it is no longer responsive, not answering to NBoot s-press.

    It is possible that during programming the nboot has been overwritten.


    Is it possible to reload a new nboot with a JTag programmer?

  • What exactly did you do? Which update tools were used?

    Which files did you program?

  • I now see this is the windows forum, using a Linux board, could this question be moved to Linux PicoCom?

    I was updating the nboot from the screen application, and probably I didn';t send it as binairy (need to check the method, if it uses binairy or not..). Just to make sure if we update it, what would happen. I know, I shouldn't have, but it happened. Bummer.


    I used the nboot v50 binairy file from the download section of the site.


    If I now connect the board to our custom carrier, it doesn't react to anything: USB, serial, display etc.


    We did get a development kit from our customer, but he probably broke that (mounted PicoCom defect.. when used on our own board it get increadibly hot very quick, don;t know what happened there, and because of that the picocom broke the devkit supply I think), so I could potentially test the PicoCom on the devkit if I fix it first.


    So I used:
    * Linux PC with 'screen' to connect to terminal with nboot (v36 I think)

    * nboot v50 bin taken from last buildroot env

    * probably non-binairy transfer of file (need to verify). Planned to do full update including U-Boot, and custom image

  • have you tried holding 's' during power-up?

    If the board does not respond to the key then the nboot is not working.


    For the PicoCOM series you need a special adapter to set it to recovery mode.

    Please send the board back with RMA.
