An Android 4.3.1 (Jelly Bean) build for the XO-4 laptop. OLPC is preparing an Android, Sugar and Gnome dual-boot system for the XO-4.
An early development release of an Android-only build is available. It is yet to be optimised for performance. In particular, the graphics are very slow. The build is based on our arm-3.5 kernel, with changes which can be found in the arm-3.5-android branch of our olpc-kernel repository. To install it: - make a backup of anything you want to keep on the XO-4, because it will be erased by this test, - ensure the firmware is upgraded to Q7B37, - determine the size of your eMMC internal storage; it will be either 4GB or 8GB, and is shown by the firmware just before the ok prompt, - download the corresponding .zd file, - at the ok prompt, type this: fs-update u:\a4g.zd - when the installation completes, type this: boot Known problems: - very slow screen response due to graphics driver needing work, to the point of being impractical, - the power button may not be operational, or may not operate in the fashion that Android devices normally provide, - Bluetooth is not operational, - USB may not be operational, - the touchpad is not implemented, - the ambient light sensor is not implemented, - the e-book switch is not implemented, - the microphone jack may not be operational, - the headphone hack may not be operational, Do not rely on this build for any critical data. -- James Cameron http://quozl.linux.org.au/
