LetuxOS: U-Boot

This project provides a bootloader for the supported devices.

It is based on the master branch of the official U-Boot git and we regularily merge their lastest changes. See also http://omappedia.org/wiki/Bootloader_Project.

It follows these principles:

• based on mainline U-Boot
• adds a handfull of private commands
• KISS (keep it simple and stupid)
• is configured through boot.scr
• by supporting the framebuffer base address, splash and menu images can be loaded from boot media
• allows for touch screen detection - and graphical boot menu
• we aim for full integration into the mainstream U-Boot

Features

• supports a Touch-Screen based Boot-Menu
• can scan up to 4 partitions on the SD card for different operating systems (multi-boot)
• allows to test LEDs, Buttons, TSC2007, GPS
