Userspace Update

  • Kodi to 17.0
  • libcec to 4.0
  • Ubuntu to 16.04.2

Tips and Known issues

  • mySQL/KVM needs an editing of boot.ini file to change the system timer source to ARMv8 Architecture from the Meson. But the ARMv8 timer affects the VPU/GPU system accuracy.
  • NTP time syncing takes long time (sometimes around 1~2 minutes)
  • GPU acceleration should be enabled manually. Add below line into /etc/chromium-browser/default file.
    CHROMIUM_FLAGS=" --use-gl=egl --ignore-gpu-blacklist --disable-accelerated-2d-canvas --num-raster-threads=2"
  • The root file system will be resized in the first booting process. OS will reboot automatically to complete the resizing process. This process must not be interrupted.
  • To enable Auto-login, edit /usr/share/lightdm/lightdm.conf.d/60-lightdm-gtk-greeter.conf file like this.

Reverting to Kodi 16.1

  • If Kodi 17 isn't working fine for you, you can revert to 16.1 with the following steps.
    wget deb.odroid.in/old_kodi_c2/old_kodi.tar
    tar xf old_kodi.tar
    sudo dpkg -i *.deb

How to update the kernel and system

  • sudo apt update && sudo apt upgrade && sudo apt dist-upgrade && sudo apt install linux-image-c2
