OBoot

Oboot is a bootloader for the Open Firmware environment. It is designed to be highly configurable and extensible, allowing it to be used in a wide variety of embedded systems. Oboot supports booting from various storage devices, including NAND flash, SD cards, and eMMC. It also includes support for network booting using protocols such as TFTP and NFS.

One of Oboot's key features is its ability to load and execute multiple operating systems. This is achieved through a flexible boot script mechanism that allows users to define custom boot sequences. Oboot can also pass arguments to the loaded operating system, enabling further customization of the boot process. The bootloader is written in C and is typically compiled for specific target architectures.

Oboot is commonly found in embedded systems that utilize PowerPC or ARM processors. Its modular design makes it suitable for applications where resources are constrained, and a lightweight yet powerful bootloader is required. The project is open-source and is often used in conjunction with the Buildroot build system for embedded Linux development. Documentation for Oboot typically details its configuration options, command-line interface, and scripting capabilities. Developers can adapt and extend Oboot to meet the specific needs of their hardware and software projects.
