| 4 | Building the Test Secure Payload |
| 5 | -------------------------------- |
| 6 | |
| 7 | The TSP is coupled with a companion runtime service in the BL31 firmware, |
| 8 | called the TSPD. Therefore, if you intend to use the TSP, the BL31 image |
| 9 | must be recompiled as well. For more information on SPs and SPDs, see the |
| 10 | :ref:`firmware_design_sel1_spd` section in the :ref:`Firmware Design`. |
| 11 | |
| 12 | First clean the TF-A build directory to get rid of any previous BL31 binary. |
| 13 | Then to build the TSP image use: |
| 14 | |
| 15 | .. code:: shell |
| 16 | |
| 17 | make PLAT=<platform> SPD=tspd all |
| 18 | |
| 19 | An additional boot loader binary file is created in the ``build`` directory: |
| 20 | |
| 21 | :: |
| 22 | |
| 23 | build/<platform>/<build-type>/bl32.bin |
