  • [RPi4] HDMI problems after upgrade to 12.2.1 + solution

    I upgraded the RPi4 from 12.0.2 to 12.2.1 and had HDMI problems.
    After first reboot the TV screen looked shifted. I the system settings only 1024x768, 800x600 and other typcal PC monitor resolutions were offered. The HDready resolution was not listed. HDMI audio did also not work and was not listed as an option.

    (my setup is an old Panasonic plasma TV with HDready resolution connected directly to the RPi4. The sound is played by the TV over the HDMI interface)

    Starting with the second reboot the TV did not show the KODI logo. Only, the "12.2.1" message is displayed - then the TV picture stayed dark.

    I flashed another µSD card with the old version 12.0.2 and booted this image. The "12.0.2" message was shown, but still the boot process seemed to stop (no KODI logo displayed and the TV stayed dark). - and this was the LibreELEC version that was used for months (of course with working TV and sound)!


    The solution for me.

    In the end I connected a 24" fullHD Samung PC monitor to the RPi4 with the 12.2.1 µSD card. (The old monitor just has VGA and DVI inputs - so, an DVI to HDMI adapter was used). The RPi4 successfully booted LibreELEC.
    Then the HDready TV was reconnected - and picture and HDMI sound work as expected.
    The kids use it for several days without a problem.

    I hope, this is of help for some LibreELEC users.

    Thank you for making LibreELEC.

  • What does "100" inside a blue circle mean? RPi4 freezing

    Dear LibreELEC experts.

    A few weeks ago, my Raspberry Pi 4 (2GB, "Full Armor" case, original 3A power supply) started to freeze when playing (skipping through) h264 videos.

    It always starts with a white "100" and a blue circle around in the middle of the TV. Then, after a few seconds the picture+sound completely freezes and my remote ssh session is stopped ("Timeout, server libreelec not responding.").

    I could not find out (Wiki/search) what the "100" is telling me.

    Please, help.

    Michael

    PS: a few things that I tried.

    * The problem appears with LibreELEC versions 9.2.latest and 11.0.3

    * I copied the .m4v file to the µSD card and the freeze also happens when playing from smb (1GBit/s LAN; Ubuntu 22.04LTS fileserver) and when playing from µSD card of the RPi4

    * The .m4v file plays fine on a Windows 10 PC and a Linux notebook with VLC

    * I wrote (dd) the LibreELEC 11.0.3 image on a different SanDisk Ultra µSD card. The same freeze happens.

    * beeing logged in remotely via ssh I triggered by skipping through the .m4v (left-clicking with the mouse on the time bar) the "100" and the following freeze
