| ############################# |
| |
| Overview |
| ******** |
| |
| This board configuration uses Armv8-R AEM FVP [1]_ to emulate a generic |
| Armv8-R [2]_ 32-bit hardware platform. |
| |
| Fixed Virtual Platforms (FVP) are complete simulations of an Arm system, |
| including processor, memory and peripherals. These are set out in a |
| "programmer's view", which gives you a comprehensive model on which to build |
| and test your software. |
| |
| The Armv8-R AEM FVP is a free of charge Armv8-R Fixed Virtual Platform. It |
| supports the latest Armv8-R feature set. Please refer to FVP documentation |
| page [3]_ for more details about FVP. |
| |
| To Run the Fixed Virtual Platform simulation tool you must download "Armv8-R AEM |
| FVP" from Arm developer [1]_ (This might require the user to register) and |
| install it on your host PC. |

| Hardware |
| ******** |
| |
| Supported Features |
| ================== |
| |
| The following hardware features are supported: |
| |
| +-----------------------+------------+----------------------+ |
| | Interface | Controller | Driver/Component | |
| +=======================+============+======================+ |
| | GICv3 | on-chip | interrupt controller | |
| +-----------------------+------------+----------------------+ |
| | PL011 UART | on-chip | serial port | |
| +-----------------------+------------+----------------------+ |
| | Arm GENERIC TIMER | on-chip | system clock | |
| +-----------------------+------------+----------------------+ |
| |
| The kernel currently does not support other hardware features on this platform. |
| |
| When FVP is launched with ``-a, --application FILE`` option, the kernel will be |
| loaded into DRAM region ``[0x0-0x7FFFFFFF]``. For more information, please refer |
| to the official Armv8-R AEM FVP memory map document [4]_. |
| |
| Devices |
| ======= |
| |
| System Clock |
| ------------ |
| |
| This board configuration uses a system clock frequency of 100 MHz. |
| |
| Serial Port |
| ----------- |
| |
| This board configuration uses a single serial communication channel with the |
| UART0. |
| |
| Programming and Debugging |
| ************************* |
| |
| Use this configuration to build basic Zephyr applications and kernel tests in the |
| Arm FVP emulated environment, for example, with the :ref:`synchronization_sample`: |
| |
| .. zephyr-app-commands:: |
| :zephyr-app: samples/synchronization |
| :host-os: unix |
| :board: fvp_baser_aemv8r_aarch32 |
| :goals: build |
| |
| This will build an image with the synchronization sample app. To run with FVP, |
| first set environment variable ``ARMFVP_BIN_PATH`` before using it. Then you |
| can run it with ``west build -t run``. |
| |
| .. code-block:: bash |
| |
| export ARMFVP_BIN_PATH=/path/to/fvp/directory |
| west build -t run |
| |
| Debugging |
| ========= |
| |
| Refer to the detailed overview about :ref:`application_debugging`. |
