This is the barebox user manual, which describes how to configure, compile and run barebox on embedded systems.
barebox (just barebox, not the barebox) is a bootloader designed for embedded systems. It runs on a variety of architectures including x86, ARM, MIPS, PowerPC and others.
barebox aims to be a versatile and flexible bootloader, not only for booting embedded Linux systems, but also for initial hardware bringup and development. barebox is highly configurable to be suitable as a full-featured development binary as well as for lean production systems. Just like busybox is the Swiss Army Knife for embedded Linux, barebox is the Swiss Army Knife for bare metal, hence the name.
