The Hardkernel ODROID-C2 is a single-board computer.
- Amlogic S905 SoC
- 4x ARM Cortex-A53 CPU
- 2 GB RAM
- 4x USB, 1x USB OTG
- 1x GbE
- 1x HDMI
- 40-pin largely Raspberry Pi compatible header (except pins 37, 38, 40)
Writing a disk image to the SD card
- Download the image you want (Leap is stable, Tumbleweed is rolling) from here:
This image uses the Tumbleweed kernel and userspace, but relies on firmware packages and tools not in Tumbleweed.Version:Tumbleweed
If the direct links above do not work for you (as we are constantly building new images), please check the general download directory for the images.
- As root extract the image onto your SD card (replace sdX with the device name of your SD card).
WARNING: all previous data on the SD card will be lost. Check first if the device you have selected is really your SD card!
xzcat [image].raw.xz | dd bs=4M of=/dev/sdX iflag=fullblock oflag=direct; sync
- Insert the SD card with the openSUSE image into your board.
- Connect the board to your PC via serial port (optional, but helpful for debugging; USB-TTL serial cable needed).
- Connect the board to your monitor (via DVI/HDMI, optional).
- Power on the board.
- Walk through the first boot steps.
- Ethernet is configured to request an IP via DHCP, check your DHCP server for the board IP if used.
- Have a lot of fun...
A u-boot-odroid-c2 package is available in Tumbleweed. From version v2017.05-rc2 on (in Base:System:Staging at the time of writing) it contains support for booting from Micro SD; before that only network boot is possible.
For the goal of creating bootable images in OBS, an experimental tool to replace Amlogic's proprietary x86_64 binary aml_encrypt_gxb is available on GitHub. The meson-tools package is used by odroidc2-firmware package.
Extract bl1.bin.hardkernel and u-boot.odroidc2 from odroidc2-firmware package.
Your SD card must be using MBR partitions (not GPT).
# dd if=bl1.bin.hardkernel of=/dev/sdX conv=fsync bs=1 count=442 # dd if=bl1.bin.hardkernel of=/dev/sdX conv=fsync bs=512 skip=1 seek=1 # dd if=u-boot.odroidc2 of=/dev/sdX conv=fsync bs=512 seek=97
The Tumbleweed kernel works.
