Additional Packages

  • X.org video driver package: xf86-video-odroid-c2
    • Note: Add your user to the "video" group to be able to access /dev/mali and /dev/ump.
  • X11 Mali EGL and GLES drivers (installed with xf86-video-odroid-c2): odroid-c2-libgl-x11
    • Note: Reboot after installation for udev rules to take effect.
  • Framebuffer Mali EGL and GLES drivers: odroid-c2-libgl-fb
  • wiringPi modified for the ODROID-C2: wiringc1

Headless Mode

For servers (ie, no need for a display), uncomment the following in /boot/boot.ini to free up approx 300M of memory at the cost of disabling the video subsystem:

setenv nographics "1"

LEDs

ODROIDs have dual LEDs: a red power LED which is always on if power is supplied, and a blue LED which can be configured.

By default, the blue LED is a heartbeat LED, which flashes when the kernel is running. This can be configured in /sys/class/leds/blue:heartbeat/trigger.

To list available triggers:

# cat /sys/class/leds/blue:heartbeat/trigger

Replace TRIGGER with one of the available triggers. This setting will apply instantly, but be lost upon reboot.

# echo TRIGGER > /sys/class/leds/blue:heartbeat/trigger

To create a persistent configuration, edit or create /etc/tmpfiles.d/leds.conf:

w /sys/class/leds/blue:heartbeat/trigger - - - - TRIGGER
