PicoCore™MX8MM Problem on Developement Board

  • Good morning,


    I recently received the PicoCore ™ MX8MM development board.

    I connected the display to the board and supply it. I visualize the image

    with the three penguins. It appears that the operating system does not

    is loaded correctly.

    Another problem is that I have a serial number on the device

    that is not recognized, so I can't access the download area.


    Br, Paolo

  • Hello,


    for the picocoremx8mm we have different rootfs images. Currently the are 2 configuration for this images:

    - Minimal has no wayland weston support.

    - Standard has wayland weston support


    First I would check which type of image is on your board. This can be done by staring weston from command line.


    On other side it is possible that on your board is sofware from the first pre release version. In this package version wayland weston does not boot automatically. But you can start it manual from the command line with following commands:


    mkdir /var/run/weston

    chmod 0700 /var/run/weston

    export XDG_RUNTIME_DIR=/var/run/weston


    weston --tty=1 --log=/var/log/weston.log


    In the new pre release package fsimx8-B2019.10-pre in our download area we added a script to start weston automatically. So you can use it too.


    Hope it helps.
