Kernel Updates

Userspace Update

  • Kodi to 17.4 (Special thanks to OverSun)
  • Ubuntu to 16.04.3
The RootFS Auto-resize feature has changed!!! 
Once everything is done after auto-resizing, the power will turn off automatically. 
Please Wait a couple of minutes and plug/unplug the power cable when the blue LED is off.
  • 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)
  • Check the CPU governor if you feel the system slowness.
    cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor

    If it is not “performance”, try

    echo 'GOVERNOR="performance"' | sudo tee /etc/default/cpufrequtils

    and reboot.

  • 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.
[Seat:*]
greeter-session=lightdm-gtk-greeter
autologin-user=odroid
  • 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
sudo apt update
sudo apt upgrade
sudo apt dist-upgrade
sudo apt install linux-image-c2 
sudo reboot
