{{Release Notes}}

== OLPC Firmware Release q4a04 2010-10-05 ==

This replaces the previous tracked release which was a bricker. It works on XO-1.75 A1 prototypes.

Supports: SD, WLAN, USB (flaky), screen, keyboard (barely tested), camera test.

The display now uses 16bpp RGB565 mode because I was tired of dealing with all the unaligned issues around the 3-byte-per-pixel RGB888 mode.

The camera test now uses the video port into the display, instead of copying the data into the frame buffer. The camera scaling is done in hardware.

The version number is now displayed in the banner.

Lots of code that was previously omitted from the build for bringup has now been compiled in, in preparation for testing stuff like graphics.

Major missing features include audio support and the use of EC commands.
