Building for SiFive CoreIP
==========================
Building an Example
-------------------
To compile a bare-metal RISC-V program:
.. code-block:: bash
make [PROGRAM=hello] [TARGET=coreip-e31-rtl] [CONFIGURATION=debug] software
The square brackets in the above command indicate optional parameters for the
Make invocation. As you can see, the default values of these parameters tell
the build script to build the ``hello`` example for the ``coreip-e31`` target
with the ``debug`` build configuration. If, for example, you wished to build
the ``timer-interrupt`` example for the S51 Core IP target with the ``release``
configuration, you would instead run the command
.. code-block:: bash
make PROGRAM=timer-interrupt TARGET=coreip-s51-rtl CONFIGURATION=release software
Cleaning a Target Program Build Directory
-----------------------------------------
The ``clean`` target can be used to restore a target program's directory to a clean state.
.. code-block:: bash
make [PROGRAM=hello] [TARGET=coreip-e31-rtl] [CONFIGURATION=debug] clean
