board support package
In embedded systems, a board support package (BSP) is an implementation of specific support code (software) for a given (device motherboard) board that conforms to a given operating system. It is commonly built with a bootloader that contains the minimal device support to load the operating system and device drivers for all the devices on the board.
Some suppliers also provide a root file system, a toolchain for building programs to run on the embedded system (which would be part of the architecture support package), and utilities to configure the device (while running).
==History==
This term has been in use since 1981 when Hunter & Ready, the developers of VRTX, first used the term to describe the hardware-dependent software needed to run VRTX on a specific hardware platform. The phrase is commonly associated with Wind River Systems for its VxWorks embedded operating system because of its extensive device driver offerings, but since the 1980's it has been in wide use throughout the industry. For example, QNX Software Systems also distributes BSPs, as does Microsoft (for its Windows CE operating system), NVIDIA and many others. In fact, virtually all RTOS providers will use the term BSP to describe the hardware support software modules available for their RTOS.
