1.. _tfm_ipc: 2 3TF-M IPC 4######## 5 6Overview 7******** 8 9This is a simple TF-M integration example that can be used with an ARMv8-M 10supported board. 11 12It uses **IPC Mode** for communication, where TF-M API calls are made to the 13secure image via an IPC mechanism, as opposed to **Library Mode**, where the 14IPC mechanism is bypassed in favor of direct calls. 15 16Zephyr uses Trusted Firmware (TF-M) Platform Security Architecture (PSA) APIs 17to run this sample in a secure configuration, with Zephyr itself running in a 18non-secure configuration. 19 20The sample prints test info to the console either as a single-thread or 21multi-thread application. 22 23The sample reboots after 5 seconds to demonstrate rebooting with TF-M. 24The sys_reboot call is routed to TF-M, since the nonsecure app is not allowed 25to perform the reboot directly. 26 27Building and Running 28******************** 29 30This project outputs test status and info to the console. It can be built and 31executed on MPS2+ AN521 and ST Nucleo L552ZE Q. 32 33On MPS2+ AN521: 34=============== 35 36#. Build Zephyr with a non-secure configuration (``-DBOARD=mps2_an521_ns``). 37 38 .. code-block:: bash 39 40 cd $ZEPHYR_ROOT/samples/tfm_integration/tfm_ipc/ 41 mkdir build 42 cd build 43 cmake -DBOARD=mps2_an521_ns .. 44 make 45 46You can also use west as follows: 47 48 .. code-block:: bash 49 50 $ west build -p -b mps2_an521_ns zephyr/samples/tfm_integration/tfm_ipc 51 52 53#. Copy application binary files (mcuboot.bin and tfm_sign.bin) to ``<MPS2 device name>/SOFTWARE/``. 54#. Open ``<MPS2 device name>/MB/HBI0263C/AN521/images.txt``. Edit the ``AN521/images.txt`` file as follows: 55 56 .. code-block:: bash 57 58 TITLE: Versatile Express Images Configuration File 59 60 [IMAGES] 61 TOTALIMAGES: 2 ;Number of Images (Max: 32) 62 63 IMAGE0ADDRESS: 0x10000000 64 IMAGE0FILE: \SOFTWARE\mcuboot.bin ; BL2 bootloader 65 66 IMAGE1ADDRESS: 0x10080000 67 IMAGE1FILE: \SOFTWARE\tfm_sign.bin ; TF-M with application binary blob 68 69#. Reset MPS2+ board. 70 71If you get the following error when running cmake: 72 73 .. code-block:: bash 74 75 CMake Error at cmake/Common/FindGNUARM.cmake:121 (message): 76 arm-none-eabi-gcc can not be found. Either put arm-none-eabi-gcc on the 77 PATH or set GNUARM_PATH properly. 78 79You may need to edit the ``CMakeLists.txt`` file in the ``tfm_ipc`` project 80folder to update the ``-DGNUARM_PATH=/opt/toolchain/arm-none-eabi`` path. 81 82On QEMU: 83======== 84 85The MPS2+ AN521 target (``mps2_an521_ns``), which is based on a 86dual core ARM Cortex-M33 setup, also allows you to run TF-M tests using QEMU if 87you don't have access to a supported ARMv8-M development board. 88 89As part of the normal build process above, a binary is also produced that can 90be run via ``qemu-system-arm``. The binary can be executed as follows: 91 92 .. code-block:: bash 93 94 qemu-system-arm -M mps2-an521 -device loader,file=build/zephyr/tfm_merged.hex -serial stdio 95 96You can also run the binary as part of the ``west`` build process by appending 97the ``-t run`` flag to the end of your build command, or in the case of 98ninja or make, adding the ``run`` commands: 99 100 .. code-block:: bash 101 102 $ west build -b mps2_an521_ns zephyr/samples/tfm_integration/tfm_ipc -t run 103 104Or, post build: 105 106 .. code-block:: bash 107 108 $ ninja run 109 110On ST Nucleo L552ZE Q or STM32L562E-DK Discovery: 111================================================= 112 113This sample was tested on Ubuntu 18.04 with Zephyr SDK 0.11.3. 114 115Build Zephyr with a non-secure configuration: 116 117 Example, for building non-secure configuration for Nucleo L552ZE Q 118 119 .. code-block:: bash 120 121 $ west build -b nucleo_l552ze_q_ns samples/tfm_integration/tfm_ipc/ 122 123 Example, for building non-secure configuration for STM32L562E-DK Discovery 124 125 .. code-block:: bash 126 127 $ west build -b stm32l562e_dk_ns samples/tfm_integration/tfm_ipc/ 128 129The script to initialize the device is available in the ``build/tfm`` folder: 130 131 - ``regression.sh``: Sets platform option bytes config and erase platform. 132 133Run them in the following order to flash the board: 134 135 .. code-block:: bash 136 137 $ ./build/tfm/regression.sh 138 $ west flash 139 140 .. note:: 141 Note that ``arm-none-eabi-gcc`` should be available in the PATH variable and that ``STM32_Programmer_CLI`` is required to run ``regression.sh`` (see https://www.st.com/en/development-tools/stm32cubeprog.html).
