ODROID-C2

The ODROID-C2 is a $40 quad-core computer, providing one of the most cost-effective ARMv8 AArch64 development boards available. Board dimensions are identical to the ODROID-C1, and it can use the same power supply or be powered through the micro USB port.

Features of the board include:

  • Amlogic S905 ARM Cortex-A53 1.5Ghz quad core CPU
  • Mali-450 MP3 GPU (OpenGL ES 2.0/1.1)
  • 2GB DDR3 SDRAM
  • Gigabit Ethernet
  • HDMI 2.0 4K/60Hz display
  • 40+7pin IO port
  • eMMC5.0 HS400 flash storage slot
  • UHS-1 SDR50 MicroSD Card slot
  • USB 2.0 Host x 4, USB OTG x 1 (power and data capable)
  • Infrared (IR) Receiver

Micro SD and eMMC Creation

Replace sdX in the following instructions with the device name for the SD card as it appears on your computer. Use the provided micro SD to eMMC adapter card to install to eMMC.

  1. Zero the beginning of the SD card or eMMC module:
    dd if=/dev/zero of=/dev/sdX bs=1M count=8
  2. Start fdisk to partition the SD card:
    fdisk /dev/sdX
  3. At the fdisk prompt, create the new partitions:
    1. Type o. This will clear out any partitions on the drive.
    2. Type p to list partitions. There should be no partitions left.
    3. Type n, then p for primary, 1 for the first partition on the drive, and enter twice to accept the default starting and ending sectors.
    4. Write the partition table and exit by typing w.
  4. Create the ext4 filesystem:
    1. For e2fsprogs < 1.43:
      mkfs.ext4 /dev/sdX1
    2. For e2fsprogs >= 1.43:
      mkfs.ext4 -O ^metadata_csum,^64bit /dev/sdX1
  5. Mount the filesystem:
    mkdir root
    mount /dev/sdX1 root
  6. Download and extract the root filesystem (as root, not via sudo):
    wget http://archlinuxarm.org/os/ArchLinuxARM-odroid-c2-latest.tar.gz
    bsdtar -xpf ArchLinuxARM-odroid-c2-latest.tar.gz -C root
  7. Flash the bootloader files:
    cd root/boot
    ./sd_fusing.sh /dev/sdX
    cd ../..
  8. (Optional) Set the screen resolution for your monitor:
    1. Open the file root/boot/boot.ini with a text editor.
    2. Uncomment the line with the desired resolution, and ensure all others are commented.
    3. Save and close the file.
  9. Unmount the partition:
    umount root
  10. Insert the micro SD card or eMMC module into the C2, connect ethernet, and apply 5V power.
  11. Use the serial console or SSH to the IP address given to the board by your router.
    • Login as the default user alarm with the password alarm.
    • The default root password is root.
