- 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
