dm900 uhd 1gb flash 1gb memory

    • check /data with df -h in telnet :D

      df -h
      /dev/root 960.4M 458.8M 436.0M 51% /
      ....
      /dev/mmcblk0p3 2.5G 30.7M 2.4G 1% /data

      The remaining memory is reserved for the kernel and not visible to userspace (like when your grapics card on your PC is using part of main memory instead of having their own)

    • thanx for quick reply
      but when you have 4gb flash memory 75% used by kernet and 50% of memory hiden sint normal especially when i restart a box i got 730mb free memory after some time the memory decrease to 30mb i have to restart a box to recover memory.
      in the past i have dm8000 there is a version of Oe which recover space on flash is there a chance to see more space recovered with ,new image in the feature or we are condamned with limited space and memory
      anyway i am satisfied with this box

    • First of all you seem to confuse flash space and memory.

      The flash has 4000 MB which are split into ~1 GB for the root partition (even with picons this ought to be more than enough) and the remaining space can be used in the /data partition. Don't mind the few 100 MB that get lost in the GB to GiB conversion.
      In Telnet you can check the state of the flash with df -h / and df -h /data
      And as you can see on your screenshot youself. Right now you still have half of the flash empty. My 800se was always at 70-95% flash usage ;)

      Then there is the memory aka RAM. As you can see in your Screenshot the memory is also not fully available. This is because half of the memory is reserved for the GPU (similar as most Notebooks do it), which displays the OSD and other stuff (e.g. 3D Animations, Covercollection, etc.).

      Regarding your "issues" with filling up memory: This is totally normal and no problem whatsoever! The default Linux memory strategy always fills up the whole available RAM and only removes stuff from the RAM if it really needs to.
      Of course there might be ways to manually free up some memory but this shouldn't be necessary. Their either is enough space (and then Linux will use all of it) or there isn't (then you would need a SWAP). If you are not using any special software (e.g. Kodi, Full-Debian or other Desktop-Software) the remaining 1 GB will always be enough.
      The command to check the RAM is free -m
