U-Boot, short for Universal Boot Loader, is an open-source project governed by the GPL license. It plays a crucial role in the boot process of embedded systems, acting as the first software to run before the operating system kernel takes over. Originally derived from projects like FADSROM, 8xxROM, and PPCBOOT, U-Boot has evolved into a powerful and flexible bootloader with a structure and compilation method similar to the Linux kernel. Many of its source files are directly inspired by or adapted from Linux kernel code, especially device drivers, which can often be seen reflected in the comments within the code.
As a bootloader, U-Boot initializes hardware components, sets up memory maps, and prepares the system environment to ensure a smooth transition to the operating system. In embedded systems, where there is typically no BIOS-like firmware, U-Boot handles the entire boot sequence. For example, on ARM7TDMI-based systems, the boot process usually starts at address 0x00000000, where the bootloader resides and takes control immediately after power-on or reset.
U-Boot operates in two main modes: **boot loading mode** and **download mode**, both offering extensive functionality typical of advanced bootloaders. It supports a wide range of features, including:
- SCC/FEC Ethernet support
- BOOTP/TFTP booting
- IP and MAC address configuration
- Online reading and writing of FLASH, DOC, IDE, IIC, EEROM, and RTC
- Serial port support for Kermit and S-record downloads
- Recognition of binary, ELF32, and pImage formats, with special support for Linux kernels
- A comprehensive set of monitor commands for memory, I/O, registers, and peripheral testing
- Scripting capabilities similar to BASH
- Support for WatchDog timers, LCD display, and status indicators
U-Boot is highly versatile, supporting a wide variety of processor architectures and providing numerous peripheral drivers. It also supports multiple file systems and includes tools for debugging, scripting, and booting. This makes it particularly valuable for Linux-based board porting. The 1.1.1 version, for instance, included specific support for SA1100 and 44B0 chips, focusing on board-level porting tasks such as FLASH initialization, memory configuration, and serial port settings. Its robust functionality and ongoing development make system upgrades and maintenance significantly easier and more efficient.
Types of Intel Motherboard
