RPI4 reboot = HDMI signal loss

  • Hi everybody!
    First of all thanks to everyone involved in this project for this fantastic piece of software!


    i have but one problem that whenever i reboot my RPI4, the TV loses the HDMI signal (using the internal grabber and the RPI4-Kodi as source)
    what happens is LE shuts down and the RPI4 reboots. i can even see the LE splashscreen and the hyperion LED swirl but after that the signal just craps out.LE itself seems to boot up as it should as i can control kodi with kore and SSH into the machine but no matter what i do i cannot get the HDMI signal back (rebooting again also doesn't help). The only thing that gets the signal back is to disconnect the power, wait for ~20sec and plug the power back in.


    i have already asked this on the LE forums and apparently the workaround is to add a delay to the hyperion startup forcing it to wait until kodi is fully loaded and then initialize hyperion

    Zitat


    The other issue I frequently see here is no HDMI signal at all after a cold boot (on my 4kp60 screen) if Hyperion is active. A simple workaround for that is to start Hyperion after Kodi has started, I'm using a simple systemd drop-in here to do that:
    .config/system.d/service.hyperion.service.d/delay.conf


    (see https://forum.libreelec.tv/thr…?postID=130791#post130791 for details). However the guy who came up with this idea installed hyperion via the LE-app.


    Since this website recommends NOT using the LE-addon but instead install hyperion through PC via SSH Hypercon this is what i did. That however means that running "systemctl status service.hyperion" returns "Unit service.hyperion.service could not be found."


    Now, can anyone help me to get this delay working on my setup? I am hesitant to just install the LE addon over the existing installation as i don't want to break things now that they are working (well sort of..)


    Still new to this so any help would be much appreciated, thanks!
