  • How to switch OFF the USB 5V RPi3 in LibreELEC

    The shutdown command will not turn off 5V completely - it goes to standby. In standby it will listen to GPIO, and can be switched on with a GPIO button.

    I have been installed a power on/off button at my RPi3B+, which works perfectly with LibreELEC. Read this thread for instructions. If I understand you right, your timer will do a complete 5V power off after the shutdown.

    PS: With the off-button.py script (see linked thread) you can trigger a GPIO signal right before shutdown. If you listen to that GPIO "off" signal with your timer, it should work.

    However, although I can set the resolution to 576 or 1080 lines, set the Vertical sync to 50Hz but I cannot set the Horizontal Sync frequency from 31KHz to 15.6KHz in the LibreElec menu. There is no option. How can I find out if my card supports this option and how can I set it?

    Yes, there is no option for horizontal frequencies.

    You will find this XML tag in your guisettings.xml:

    Code
    <setting id="videoscreen.whitelist">

    It contains all possible resolutions / vertical frequencies for the output device.

    If whitelist changes from time to time with the same output device, it indicates a connection problem.

    The I2S line looks good.

    This lines of your log are a potential problem:

    I don't have those pulseaudio warnings in my kodi.log, but I don't have a Hifiberry shield.

    Maybe user HiassofT can have a look at his log to verify whether the warnings are critical or not.

    You mean, I should try out something like this?

    No, I mean an adapter, which has one HDMI input, and two HDMI outputs. But your adapter could be right, if you don't have a receiver with HDMI.

    That Hifiberry shield is special RPi hardware. That's why I expect a driver problem. So, giving a kernel log may help to see, whether the driver has been loaded.

    It uses the I2S sound port that connects directly to the CPU without the need for an additional USB conversion.

    The I2S is the the keyword to search for in the kodi log. That means, there is no special Hifiberry driver.

    Can you check your config.txt please? Those lines should be in it:

    Code
    dtoverlay=hifiberry-digi
dtdebug=1

    One way of manually expanding the current system partition is to use a tool called Gparted. You can create a Linux bootable USB stick and adjust your disk partitions with it.

    @Pashovski:

    I agree. If you can boot from an external device, Gparted is the right way to expand the partition.

    Can you boot from an external device?

    Or does the LibreELEC installer start, but shows an error when trying to install?

    If the installer starts, what's the error message?

    Thanks for the tip! Im looking through the options and don't see this function. I even put the skin back to stock to just in case there was a hidden menu I wasnt seeing. Is this an advanced feature?

    Some PC's have two menus: One for general settings, and one for boot order. For my notebook, I have to hold F12 right after power-on. Your manual may give an advice, how to access the menu for boot order. It could be a different key for your HTPC.

    It seems much more sensitive than the Wi-Fi built in RPi3B+ as it finds many more local Wi-Fi routers. However when it switches to 5GHz the signal strength drops dramatically and the connection drops out after a few minutes. Although its better than the 5GHZ Wi-Fi in the RPi3 the 5GHZ signal strength in that particular location is just too low so will find another solution to get more speed at that location.

    Interesting. So, receiving signals works fine, but sending signals fails. Because sending signals needs more wattage, it might be a PSU issue.
