  • ws2812-pio-rp1 Kernel Driver seems not functional on RPi5

    Thank you for looking into this! Full diagnostic log: here.

    It's interesting that (root) writes to /dev/leds0 produce no hardware output (LEDs don't light up), nothing in the log. Before I raise any issues upstream, one question I wanted to run by you, If I run:

    cat /sys/class/ws2812-pio-rp1/leds0/uevent

    on both environments, the MAJOR numer is different:

    • Libreelec: MAJOR=236 MINOR=0
    • Raspbian: MAJOR=509 MINOR=0

    The character device is registered with completely different major numbers. Could this mean LibreELEC might be using a different version of the ws2812-pio-rp1 driver. (Is it built on https://github.com/raspberrypi/linux? ) - EDIT: Yes seems so!

    Thanks for the insights!

  • ws2812-pio-rp1 Kernel Driver seems not functional on RPi5

    Dear LibreELEC team. First of all, thank you for your wonderful OS. I'm running Kodi on a Raspberry 5. And I have a request: I'm trying to get HyperHDR working on Libreelec with a ws2812. The ws2812-pio-rp1 kernel module loads successfully but does not actually control WS2812/SK6812 LEDs on Raspberry Pi 5. I see a dependency on rp1-pio is not there.

    If possible, please include the rp1-pio.ko kernel module in LibreELEC builds for Raspberry Pi 5.

    Tested Versions

    • LibreELEC 12.2 stable (kernel 6.12.40) - NOT working
    • LibreELEC nightly (kernel 6.12.55) - NOT working
    • Raspberry Pi OS Trixie (kernel 6.12.47) - WORKING

    Test Setup

    /flash/config.txt

    Code
    dtoverlay=ws2812-pio,gpio=18,num_leds=210,rgbw

    Device is created

    Code
    ls -l /dev/leds0
crw------- 1 root root 236, 0 Jun 26 10:44 /dev/leds0

    Driver loads

    Code
    dmesg | grep ws2812
[2.939] ws2812-pio-rp1 ws2812_pio@12: Instantiated 210 LEDs on GPIO 18 as /dev/leds0

    But writing to device does nothing

    Code
    printf '\xFF\x00\x00\x00' > /dev/leds0

    on Raspian I see the first LED light up with the exact same command.

    Verification

    The exact same hardware, dtoverlay config, and test commands work perfectly on Raspberry Pi OS but fail on LibreELEC with identical kernel module version. LibreELEC compiles rp1-pio as builtin, but it never actually initializes at boot. The ws2812-pio-rp1 module loads but has no working PIO controller to communicate with.

    Thank you for your support with this!

  • [RPi5] Running StepMania OutFox on LibreELEC

    Hi everyone,

    I’ve been trying to run StepMania OutFox on my Raspberry Pi 5 running LibreELEC, but I’m encountering an issue with missing OpenGL libraries. Here’s the situation:

    Steps I’ve Taken:

    1. I downloaded and extracted the latest version of StepMania OutFox to /storage/outfox-alpha.

    2. When I try to run it via SSH with:

      Code
      ./OutFox

    I get the following error:

    Code
    ./OutFox: error while loading shared libraries: libGL.so.1: cannot open shared object file: No such file or directory

    To troubleshoot:

    • I verified that LibreELEC’s base system doesn’t include libGL.so.1.
    • Tried running StepMania OutFox in a Docker container with an ARM-compatible image (arm64v8/ubuntu) OutFox still fails to launch.

  • Raspberry 5 (RPi5) No 4kp60

    I'm on a Raspberry 5 on a 55" OLED 4K Smart TV S93C (2023). I'm having trouble getting 60Hz.

    Kodi

    Resolutions offered:

    • 4096x2160p offers 23.09, 24.00, 29.09 or 30 Hz.
    • 2560x1440p offers 60.00 Hz only.

    LibreELEC & eeprom:

    LibreELEC: Nightly-20231124-52b450b 12.0

    rpi-eeprom-update
    BOOTLOADER: up to date
      CURRENT: Mon Oct 30 16:45:10 UTC 2023 (1698684310)
       LATEST: Mon Oct 30 16:45:10 UTC 2023 (1698684310)

    Specs:

    1. Raspberry pi 5
    2. TV: 55" OLED 4K Smart TV S93C (2023)
    3. Cable: Silkland Micro HDMI to HDMI 2.1 Kabel 1M (Reviews on Amazon specifically mention 4kp60

    What I tried already:

    Adding ``to /flash/config.txt:

    hdmi_enable_4kp60
    hdmi_group=1

    I also tried the second HDMI port of the raspberry (Just loose CEC and same resolution on 30Hz)

    happy to learn if you have any suggestions, thanks! :thumbup:

  • Raspberry PI 5

    Thanks Chewitt!

    I found one issue, that when I try to render anything with the provided ffmpeg, it's looking for the hardware encoder and fails:

    Code
    /storage/.kodi/addons/tools.ffmpeg-tools/bin/ffmpeg -i /storage/test.mkv -codec:v:0 h264 /storage/output.m3u8


[h264_v4l2m2m @ 0x991e2a0] Could not find a valid device
[h264_v4l2m2m @ 0x991e2a0] can't configure encoder

    So instead I'm using docker to make use of the software encoding:

    Code
    docker run --rm -v "/storage/:/storage/" lscr.io/linuxserver/ffmpeg:latest -i /storage/test.mkv -c:v libx264 /storage/output.m3u8

  • Raspberry PI 5

    Hey LibreElec community. I have just received my Raspberry PI 5 and put the latest nighty build `LibreELEC-RPi5.aarch64-12.0-nightly-20231101-e7215dd`.

    After the resizing step, it rebooted, then I got a strange error (something about missing UUID and cannot boot), dropping to shell. Then I rebooted the device and Kodi came up!

    First impression: so much faster then on my Raspberry 4. Thanks to the LibreElec team for supporting Raspberry 5!

  • Hardware recommendation for solely LE

    Quote from chewitt

    RPi4 2GB and up .. because it's a simple playback device and the Foundation provides the best vendor support of all hardware we run on.

    Thank you for your guidance. I found this thread after reading on the homepage: "

    We can offer stable and good working versions for Allwinner, Generic and Rockchip devices. The RPi4 is also in good shape but the codebase is rather new, so it is not polished yet (keep reading for details)."

    Would you say that today the Raspberry is the recommended minicomputer to run Libreelec on?

    Thanks

  • USB HDD standby - Can sdparm be added to the distro?

    chewitt Thanks for the tip and response, I didn't realize/think of pulling binaries from raspberryOS... that's worth trying out. I actually run docker-compose as a bin as well... I'll post here if successful.. for now it's running - albeit a bit over engineered.

    GDPR-7 Thanks for the suggestion. Unfortunately hdparm doesn't work on this type/brand of disk. (Western Digital)... wish I bought Seagate like I did before.

  • [Tip] Docker user? Consider disabling Docker-proxy

    I have some docker containers interacting with each other. Saw often 'docker-proxy' using a lot of CPU. After disabling, not only the process is gone, also other processes are more smooth. including kodi.bin!

    Curious about others experience. Mileage may vary.


    Edit this file:

    Code
    /storage/.kodi/userdata/addon_data/service.system.docker/config/docker.conf

    and add '--userland-proxy=false'.

    Code
    DOCKER_DAEMON_OPTS="--data-root=/storage/.kodi/userdata/addon_data/service.system.docker/docker --userland-proxy=false"
DOCKER_STORAGE_OPTS="--storage-driver=overlay2 --storage-opt overlay2.override_kernel_check=1"
