ODROID

The configuration package odroid/common contains common configurations for the Odroid series of boards by HardKernel. There are specific packages for each board/series.

Getting Started

Set the comma-separated SKIFF_CONFIG variable:

$ export SKIFF_CONFIG=odroid/xu
$ make configure                   # configure the system
$ make compile                     # build the system

Once the build is complete, we will flash to a MicroSD card to boot. You will need to sudo bash for this on most systems.

$ sudo bash             # switch to root
$ export ODROID_SD=/dev/sdz # make sure this is right! (usually sdb)
$ make cmd/odroid/common/format  # tell skiff to format the device
$ make cmd/odroid/common/install # tell skiff to install the os

You only need to run the format step once. It will create the partition table and flash u-boot to the beginning of the drive. The install step will overwrite the current Skiff installation on the card, taking care to not touch any persistent data (from the persist partition). It's safe to upgrade Skiff independently from your containerized environments.

Note: if Docker is upgraded between Skiff versions, we can't vouch for Docker not breaking backwards compatibility at that time, however; this change would usually only happen between major Skiff/Buildroot releases if so.

Board Compatibility

There are specific packages tuned to each model. The boards are all actively tested by the developers unless otherwise noted.

Board	Config Package	Status
u + u2	odroid/u	Ethernet Issue
c2	odroid/c2
[xu3]	odroid/xu
xu4 (+ xu4q)	odroid/xu
hc2	odroid/xu
n2	odroid/c4	Reboot issue
c4	odroid/c4	Reboot issue

SD Card Compatibility

The current SD cards used / tested by developers are:

• PNY Turbo Performance 16GB High Speed MicroSDHC Class 10 UHS-1
• SanDisk 128GB Extreme MicroSDXC UHS-I
• SanDisk 64GB Ultra MicroSDXC UHS-I

The current cards that are known to NOT work are:

• Intenso MicroSDXC Card, UHS-I, 64 GB

Some SD cards may not be compatible with the Odroid kernel.

Bootup Process

All Odroid boards use u-boot. U-boot is flashed to the beginning of the SD card, before the first partition. It loads and executes a boot.ini configuration.

Note: there may be some binary bootloader blobs used that are provided by the vendor & signed, and cannot be compiled by Skiff, depending on the board.

Thank you to tobetter for patching / testing the latest Linux kernels for the Odroid series of boards.
