AcmeBoot is a small and fast bootloader that boots the Linux Kernel uimage directly from microSD without using anymore u-Boot.
AcmeBoot will be the default FOX Board G20 boot loader starting from September 2010.
Features
* Compatible with microSD HC
* Fast boot time, just 400ms to boot the Debian Linux Kernel uimage (3.5MB) saving up to 5 seconds to the boot time.
* Based on the Atmel AT91Bootstrap loader version 3.0 sources

Introduction
The very fist piece of code executed by the FOX Board G20 at the startup is RomBOOT. This firmware is burned inside the Atmel CPU and for first it tries to find executable code on the Dataflash memory.
