Board Support Package library
|
|
|
|
This directory contains the source for the libbsp.a library.
|
|
For each supported board $(RTEMS_BSP) there is a standard
|
|
set of functions which must be provided in the BSP:
|
|
|
|
+ start up initialization
|
|
+ exit support
|
|
+ set vector
|
|
+ console IO support
|
|
+ drivers
|
|
|
|
In addition, the BSP also determines the memory usage by providing
|
|
any necessary linker scripts.
|
|
|
|
There are also "generic" drivers in this directory. Currently
|
|
they are shmdr and stubdr.
|
|
|
|
Some of the supplied generic drivers (for example, shared memory) require
|
|
target board specific support routines.
|
|
|
|
NOTE: The library libbsp.a is actually built by $(RTEMS_BSP)/wrapup/Makefile.
|
|
|
|
To execute all of the test in the RTEMS Tests Suites the following
|
|
device drivers must be supplied:
|
|
|
|
+ Clock Tick
|
|
+ IO Driver Support
|
|
+ Timer
|
|
+ Shared Memory Driver Support
|
|
|
|
The Timer Driver is used only by the Timing Test Suite (c/src/tests/tmtests/*).
|
|
These tests are used to generate the execution times for RTEMS found in the
|
|
flyers. It is recommended that these tests be run to verify a port to a new
|
|
CPU or with a newly developed BSP. Looking at the times as compared to a
|
|
known CPU and target can yield insights into potential performance problems
|
|
in either the port, the BSP, or the target hardware.
|
|
|
|
The Shared Memory Support is only required to execute the Multiprocessor
|
|
Test Suite (c/src/tests/mptests/*). Multiprocessing is not a required part
|
|
of a BSP.
