ODROID-C1

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 partition:
   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://os.archlinuxarm.org/os/ArchLinuxARM-odroid-c1-latest.tar.gz
   bsdtar -xpf ArchLinuxARM-odroid-c1-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 C1, connect ethernet, and apply 5V power.
11. Use the serial console (with a null-modem adapter if needed) 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.
12. Initialize the pacman keyring and populate the Arch Linux ARM package signing keys:

    pacman-key --init
    pacman-key --populate archlinuxarm
