@chapter BSP Questions

The items in this category provide answers to questions

commonly asked about BSPs.

@section What is a BSP?

BSP is an acronym for Board Support Package.

A BSP is a collection of device drivers, startup code, linker scripts,

and compiler support files (specs files) that tailor RTEMS for a

particular target hardware environment.

@section What has to be in a BSP?

The basic set of items is the linker script, bsp_specs, and startup code.

If you want standard IO, then you need a console driver. This is needed

to run any of the RTEMS tests.  If you want to measure passage of time,

you need a clock tick driver.  This driver is needed for all RTEMS tests

EXCEPT hello world and the timing tests.  The timer driver is a benchmark

timer and is needed for the tmtests (timing tests).  Sometimes you will

see a shmsupp directory which is for shared memory multiprocessing

systems.  The network driver and real-time clock drivers are optional

and not required by any RTEMS tests.
