LE10 fixed EDID on RPi4 - Scripts

    This is probably more for HiassofT ...

    You mentioned EDID scripts for LE10 on RPi4 here:

    RE: HDMI Passthrough RPi4 - AVR detection

    Thanks a lot for reporting back and I'm glad it's working now!

    I expected that the video= option is needed, without it linux doesn't detect that AVR.

    I'm currently working on a script to simplify this whole edid stuff - hopefully that should make it into beta2.

    I'm not 100% sure why hdmi_ignore_cec_init doesn't seem to work - make sure everything's set up correctly in kodi's CEC settings (though CEC should only be ever used on hdmi0 in kodi/linux - so it's puzzling why your AVR turns on).

    so long,

    And I see this GitHub commit:

    Merge pull request #5264 from HiassofT/le10-edid-cpio · LibreELEC/LibreELEC.tv@51e371e · GitHub

    Is there a bit of documentation on how to use it?

    Would it work in fixing EDID for both HDMI connections in case of a dual-headed setup (HDMI0 on TV, HDMI1 on receiver)?

    Many thanks!

    The "getedid" script works exactly like the one on x86, which is documented on the wiki https://wiki.libreelec.tv/configuration/edid

    "getedid create" makes current EDIDs permanent (this also honors a receiver on HDMI-2) and "getedid delete" deletes those.

    It would be great to get some more feedback if it all works (so far I think I'm the only one who tested this) or if there are issues I might have missed.

    so long,

    Yup, it worked for me, rebooting fine with everything in place even with the AVR and TV in stand-by!

    All files in their right places, with the expected content.

    Relevant dmesg lines:

    Code

[    1.509751] [drm] Got external EDID base block and 1 extension from "edid/edid-HDMI-A-1.bin" for connector "HDMI-A-1"

    I'll most probably test the delete function and dual-headed scenario later today, then report back!

    Thanks for this!

    Ìt's not exactly the same, at least "gpu" parameter is missing at RPi 4 and "help" does not work.`

    LE:~ # getedid

    /usr/bin/getedid create|delete|help

    LE:~ # getedid help

    /usr/bin/getedid create|delete|help

    Yea, "gpu" wouldn't make much sense on RPi :) help output should probably be extended a bit.

    getedid on Generic/x86 also doesn't support multiple HDMI ports / edid, and the RPi version automatically removes any previous edid settings when you use "create" (so running "getedid delete" is not needed if something changes).

    It works to create and delete for single headed and dual headed cases. Fantastic!
