    I've been unable to install LibreELEC for RK3399 onto NanoPC T4 eMMC for a while now. I've tried with FriendlyCore Bionic and Armbian Buster installed onto eMMC.


    This is script output from "LibreELEC-ARM-ALL.arm-9.80-devel-20200414164234-7071836-rk3399" build:

    Hi!

    I'm test LibreELEC-RK.arm-9.80-devel-20200127120222-6e9040d-rk3399.img on rock pi. Not boot. On screen message after kernel boot "Could not mount flash/SYSTEM".

    I'm make extlinux.conf and boot with radxa uboot. On screen message: Not found boot=LABEL.... . Replace to boot=/dev/mmcblk0p9 ... not found ...ha ... it place on /dev/mmcblk1p9 , emmc on mmcblk2 , nvme not found. This kernel only for khadas?

    I had simmilar issue with old v5.x kernel images. These steps work for me:

    1. write image to SD card

    2. write image to USB flash drive

    3. insert both into NanoPC T4 (for USB I use 3.0 port)

    4. power on NanoPC T4

    5. profit?

    I tried out "LibreELEC-RK.arm-9.80-devel-20200205122646-6e9040d-rk3399" image on NanoPC T4.

    There is interesting information about co-running the same image on two platforms simultaneously rk3399 and rk3328. This will further allow to have a shared image for rk3399 and rk3328 when upgrading via TAR. The details there is in this topic.

    It would be useful to test this option on different rk3399 and rk3328. By the way, the latest Libreelec and Armbian images use a common u-boot-2019.10, the difference is only in the configuration for the two platforms when building.

    I've also tested your images, both kernels. Kernel v4 works just like JerryPenguin reported, apart from HDMI CEC. I'm using Philips 42PFS7189/12 TV and with my old SolidRun HummingBoard Pro i2ex HDMI CEC works on that TV with the same HDMI cable.


    I've managed to get HDMI CEC running with your image and DTB from Joern-p's image, but then the sound doesn't work.



    Kernel v5 refuses to boot at all with the following error message:


    *** Error in mount_flash: mount_common: Could not mountLABEL=LIBREELEC ***
