+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

+by ``$BASE``.
