.. _QuickStartBSPBuild:
Build a Board Support Package (BSP)
===================================
You installed the tool suite in your installation prefix, cloned two RTEMS
repositories and bootstrapped the RTEMS sources in the previous sections. We
installed the tool suite in :file:`$HOME/quick-start/rtems/5` and cloned the
repositories in :file:`$HOME/quick-start/src`. We also bootstrapped the RTEMS
sources.
You are now able to build :ref:`Board Support Packages (BSPs) <BSPs>` for all
architectures where you have an RTEMS tool suite installed. To build
applications on top of RTEMS, you have to configure, build and install a BSP
for your target hardware. To select a proper BSP for your target hardware
consult the :ref:`BSPs <BSPs>` chapter. We select the `erc32` BSP.
We configure, build and install the BSP in four steps. The first step is to
create a build directory. It must be separate from the RTEMS source directory.
We use :file:`$HOME/quick-start/build/b-erc32`.
.. code-block:: none
mkdir -p $HOME/quick-start/build/b-erc32
The second step is to configure the BSP. There are various configuration
options available. Some configuration options are BSP-specific. Prepend the
RTEMS tool suite binary directory to your ``$PATH`` throughout the remaining
steps.
.. code-block:: none
cd $HOME/quick-start/build/b-erc32
export PATH=$HOME/quick-start/rtems/5/bin:"$PATH"
$HOME/quick-start/src/rtems/configure \
--prefix=$HOME/quick-start/rtems/5 \
--enable-maintainer-mode \
--target=sparc-rtems5 \
--enable-rtemsbsp=erc32 \
--enable-tests
This command should output something like this (omitted lines are denoted by
...):
.. code-block:: none
checking for gmake... gmake
checking for RTEMS Version... 5.0.0
checking build system type... x86_64-unknown-freebsd12.0
checking host system type... x86_64-unknown-freebsd12.0
checking target system type... sparc-unknown-rtems5
...
config.status: creating Makefile
target architecture: sparc.
available BSPs: erc32.
'gmake all' will build the following BSPs: erc32.
other BSPs can be built with 'gmake RTEMS_BSP="bsp1 bsp2 ..."'
config.status: creating Makefile
Building the BSP is the third step.
.. code-block:: none
cd $HOME/quick-start/build/b-erc32
make
This command should output something like this (omitted lines are denoted by
...). In this output the base directory :file:`$HOME/quick-start` was replaced
by ``$BASE``.
.. code-block:: none
