Test Secure Payload (TSP) and Dispatcher (TSPD)
|
|
===============================================
|
|
|
|
Building the Test Secure Payload
|
|
--------------------------------
|
|
|
|
The TSP is coupled with a companion runtime service in the BL31 firmware,
|
|
called the TSPD. Therefore, if you intend to use the TSP, the BL31 image
|
|
must be recompiled as well. For more information on SPs and SPDs, see the
|
|
:ref:`firmware_design_sel1_spd` section in the :ref:`Firmware Design`.
|
|
|
|
First clean the TF-A build directory to get rid of any previous BL31 binary.
|
|
Then to build the TSP image use:
|
|
|
|
.. code:: shell
|
|
|
|
make PLAT=<platform> SPD=tspd all
|
|
|
|
An additional boot loader binary file is created in the ``build`` directory:
|
|
|
|
::
|
|
|
|
build/<platform>/<build-type>/bl32.bin
