@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 reqired by any RTEMS tests.
