DM920UHD and SD Card

  • Hello, in my DM920UHD I am using the last official image of 17-10-2018 plus the GP4 plugin.
    Occasionally I use an SD card to view photos but currently my DM920 no longer recognizes any SD Card.
    I have done several tests with images of several team's and the only one that currently recognizes the SD card is OpenAtv.
    The problem is that I like the official image plus GP4 more than any other.
    Does anyone else have this problem?

  • My SD card is mounted automatically via label "hdd":

    root@dm900:~# blkid /dev/mmcblk1p1
    /dev/mmcblk1p1: LABEL="hdd" UUID="25b71edb-4c57-4904-9c85-90f90f695f90" TYPE="ext4"
    root@dm900:~# df -hT /media/hdd
    Filesystem           Type            Size      Used Available Use% Mounted on
    /dev/mmcblk1p1       ext4           29.2G      2.7G     25.0G  10% /media/hdd

    Of course the folder /media/hdd must exist.
    I have no entries in /etc/fstab for that.


  • Which kernel message are printed when you insert the card? (dmesg command)

    Which syslog messages are printed when you insert the card or try to access it? (journalctl -f)

    Sorry, but with the info given, nobody is able to have an idea on the situation. It will require you to do and drive the investigation and provide others some details (log/kernel messages) from your system.

  • Using 19-11-2018 official image plus GP4, when insert sd card, I have no messages.
    Using OpenAtv image it reads the sd card and ask me to see fotos.

    Just did the GUI setup... :)

    Checked that. Never has a sd card inserted.

    Initial setup is dmm exp. with gp4.
    Installed is for sure the devicemanager and in the setings menu is the dmm Enigma device manager disabled.

    So i inserted a sd card...

    - And it was recognized automatically.
    - Installed exfat dependencies
    - Mounted fine

    For sure Mountpoint can be adjusted if necessary..

  • Thank you very much for the explanation. Everything is fine now. Regards.
