  • 4DPi-24-HAT kernel for Debian Stretch (and/or Buster)

    So, I rather stupidly "over-upgraded" Debian on my Raspberry Pi B+ with 24-HAT all the way to Buster without first checking the docs on 4dsystems.com.au to see if it should work, and, not surprisingly, the system won't boot. If I revert to the regular RPi Debian kernel, the system boots fine and the HAT is simply ignored/off, but if I install Kernel 4.4.50 ( http://www.4dsystems.com.au/download...50_v1.0.tar.gz with instructions http://www.4dsystems.com.au/productp...heet_R_1_9.pdf ), it will not boot. The system hangs at the multi-color/rainbow boot screen.

    Is this kernel currently supposed to work with Stretch and Buster, or do I need to wait for a newer version? If it is supposed to work, I will spend more time troubleshooting; otherwise no big deal -- I'll just reinstall Debian Jessie.

    Hello,

    Welcome to the forum.

    The 4Dpi-24-HAT works perfectly well with Debian Jessie It would be best to revert back to this version until a newer version is available.

    I hope this helps

    Best regards

    Paul

        Hello,

        Welcome to the forum.

        This should work with Stretch

        On terminal:
        $ wget http://www.4dsystems.com.au/download...35_v1.0.tar.gz
        $ sudo tar -xzvf 4d-hats_4-9-35_v1.0.tar.gz -C /

        Please make sure the jumper is set to the ON/OFF position

        Best regards,

        Paul

          Yep, it worked once I moved the jumper. I used this 4DPi-24-HAT on a different RPi several years ago, and it worked fine with the jumper in the other position. I didn't notice it mentioned in the manual, guess I missed it.

          Thanks,
          Tom
