  1. Install the official Hardkernel image. Find the ODROID Android guide here.
  2. Turn off your device.
  3. Download the latest version of RTAndroid.
  4. Mount the eMMC card on your computer.
  5. Unzip the RTAndroid image and copy the contained "update" folder to the root of the eMMC partition (FAT32).
  6. Put the eMMC card back to the ODROID and boot Android.
  7. Open the terminal app on the ODROID and execute the following commands (allow Superuser if asked):
    > su
    # echo "0x03" > /sys/bus/platform/drivers/odroid-sysfs/odroid_sysfs.15/inform0
    # reboot update

The system will reboot and update. It can take up to 10 minutes until RTAndroid will be fully functional.


For debugging purposes it is useful to have access to the console messages of the Linux Kernel. To do so, the ODROID provides an UART port attached to the console. The following adapter can be used for connecting the console to an serial port of a computer: USART-USB Module Kit

With a terminal software like PuTTY the serial port can be accessed by using a Baudrate of 115200 Baud.
