edid firmware load attempted before firmware overlay

    Hi!

    I'm trying to use my Pi5 on an old bravia television, and I managed to make it work by loading the edid from the kernel command line. But this stopped working now.

    LibreELEC (community): nightly-20231222-581a2fe (RPi5.aarch64)
    pocok:~ # dmesg | grep firm

    [    3.158760] kernel-overlays-setup: added firmware from /storage/.config/firmware

    For my untrained eyes this looks like a wrong order of things. Do my eyes deceive me?

    The file is there:

    pocok:~ # ls /storage/.config/firmware/
    braviaedid.bin

    The fixup parameter does nothing useful, the output is the same without it.

    Thanks in advance.

    Please provide a full debug log.

    How to post a log (wiki)

    1. Enable debugging in Settings>System Settings>Logging
    2. Restart Kodi
    3. Replicate the problem
    4. Generate a log URL (do not post/upload logs to the forum)

    use "Settings > LibreELEC > System > Paste system logs" or run "pastekodi" over SSH, then post the URL link

    Did you create and enable the edid.cpio initrd as well?

    getedid create will all do this automatically but braviaedid.bin looks like you set this up manually.

    so long,

    No, I did not - no idea how and why should I have done it. I copied the edid from a pi zero which was able to use the tv, and this firmware load etc worked a week ago.

    You can find some - rather outdated, somewhat incorrect and PC specific - background info in the wiki here: https://wiki.libreelec.tv/configuration/edid

    Long story short: remove all the stuff you manually added, connect the RPi to your TV and reboot, then run getedid create via ssh and you are done.

    That will dump the edid of your TV to .config/firmware/edid, create the necessary edid.cpio initrd so that the edid is also available in very early boot stage - before the .config/firmware overlay is enabled and everything will be fine - no need to manually fiddle around with duming edids, adjusting config.txt and cmdline.txt etc

    so long,
