I would like to express thanks to the following:

• The OUYA dev team. (https://github.com/ouya)
• Kulve (https://github.com/kulve/)
• Enjens (https://github.com/EnJens/)
• Matt Merhar
• Stéphan Kochen (https://github.com/stephank/)
• Dmitry Osipenko (https://github.com/digetx)
• Stephen Warren (https://github.com/swarren)

Building for Ouya:

Use the Ouya-v5.8 branch.
Build the ouya_defconfig.
Copy the arch/arm/boot/zImage to someplace safe.
cat arch/arm/boot/dts/tegra30-ouya.dtb >> your safe place zImage. You need “>>” which will append the device tree binary to the zImage, > will overwrite the file.
mkbootimg —kernel —ramdisk /dev/null —output zImage-android.bin (this makes it into an android compatible file)
fastboot boot zImage-android.bin
It will mount and use the first USB hard drive partition as root (/dev/sda1).
Place a functional arm7hf linux root userland here, Ubuntu 20.04 works well.

I HIGHLY recommend hooking up a serial connection to the Ouya.

EDIT: Everything below here is old and out of date.

The following changes were made to the source code:

• Trusted Foundations support for the L2 cache controller.
• Cpufreq support for the T30 series. (This has been merged into the T20 driver in mainline.
• GPT sector forced searching for eMMC support.

The following limitations are known:

• Kernel is unstable, it has been known to panic.
• eMMC may be unstable, I’m running it slightly hotter than original, but within spec, let me know if you have issues.
• Bluetooth is enabled, but loads with a random MAC address, it will pair, but I haven’t gotten services to play nice yet.
• Audio is enabled, but I haven’t gotten it working yet.
• Video support is hit or miss, and there is very little graphics acceleration.
• Ethernet chip loads with a random MAC address.
• There is no power management to speak of.
• Power off does not work, but reboot does.

The following does work:

• Wifi (Need the OUYA firmware binaries, the open source ones do not work)
• eMMC
• Cpufreq
• RTC
• USB
• Ethernet
• Video (With Caveats)
