Zephyr board options
|
|
====================
|
|
|
|
The STM32L552e is an SoC with Cortex-M33 architecture. Zephyr provides support
|
|
for building for both Secure and Non-Secure firmware.
|
|
|
|
The BOARD options are summarized below:
|
|
|
|
+--------------------------------+-------------------------------------------+
|
|
| BOARD | Description |
|
|
+================================+===========================================+
|
|
| nucleo_l552ze_q | For building Trust Zone Disabled firmware |
|
|
+--------------------------------+-------------------------------------------+
|
|
| nucleo_l552ze_q/stm32l552xx/ns | For building Non-Secure firmware |
|
|
+--------------------------------+-------------------------------------------+
|
|
|
|
Here are the instructions to build Zephyr with a non-secure configuration,
|
|
using :zephyr:code-sample:`tfm_ipc` sample:
|
|
|
|
.. code-block:: console
|
|
|
|
$ west build -b nucleo_l552ze_q/stm32l552xx/ns samples/tfm_integration/tfm_ipc/
|
|
|
|
Once done, before flashing, you need to first run a generated script that
|
|
will set platform option bytes config and erase platform (among others,
|
|
option bit TZEN will be set).
|
|
|
|
.. code-block:: bash
|
|
|
|
$ ./build/tfm/api_ns/regression.sh
|
|
$ west flash
|
|
|
|
Please note that, after having run a TFM sample on the board, you will need to
|
|
run ``./build/tfm/api_ns/regression.sh`` once more to clean up the board from secure
|
|
options and get back the platform back to a "normal" state and be able to run
|
|
usual, non-TFM, binaries.
|
|
Also note that, even then, TZEN will remain set, and you will need to use
|
|
STM32CubeProgrammer_ to disable it fully, if required.
|
|
|
|
Connections and IOs
|
|
===================
|
|
|

110MHz, driven by 4MHz medium speed internal oscillator.
|
|
|
|

|
|
Programming and Debugging
|
|
*************************
|
|
|
|
Nucleo L552ZE Q board includes an ST-LINK/V2-1 embedded debug tool interface.
|
|
|
|
Applications for the ``nucleo_l552ze_q`` board configuration can be built and
|
|
flashed in the usual way (see :ref:`build_an_application` and
|
|
:ref:`application_run` for more details).
|
|
|
|
Flashing
|
|
========
|
|
|
|
The board is configured to be flashed using west `STM32CubeProgrammer`_ runner,
|
|
so its :ref:`installation <stm32cubeprog-flash-host-tools>` is required.
|
|
|
|
Alternatively, OpenOCD or pyOCD can also be used to flash the board using
|
|
the ``--runner`` (or ``-r``) option:
|
|
|
|
.. code-block:: console
|
|
|
|
$ west flash --runner openocd
|
|
$ west flash --runner pyocd
|
|
|
|
Support can be enabled for pyOCD by adding "pack" support with the
|
|
following pyOCD commands:
|
|
|
|
.. code-block:: console
|
|
|
|
$ pyocd pack --update
|
|
$ pyocd pack --install stm32l552ze
|
|
|
|
Flashing an application to Nucleo L552ZE Q
|
|
------------------------------------------
|
|
|
|
Connect the Nucleo L552ZE Q to your host computer using the USB port.
|
|
Then build and flash an application. Here is an example for the
|
|
:zephyr:code-sample:`hello_world` application.
|
|
|
|
Run a serial host program to connect with your Nucleo board:
|
|
|
|
.. code-block:: console
|
|
|
|
$ minicom -D /dev/ttyACM0
|
|
|
|
Then build and flash the application.
|
|
|
|
.. zephyr-app-commands::
|
|
:zephyr-app: samples/hello_world
|
|
:board: nucleo_l552ze_q
|
|
:goals: build flash
|
|
|
|
You should see the following message on the console:
|
|
|
|
.. code-block:: console
|
|
|
|
Hello World! arm
|
|
|
|
Debugging
|
|
=========
|
|
|
|
You can debug an application in the usual way. Here is an example for the
|
|
:zephyr:code-sample:`hello_world` application.
|
|
|
|
.. zephyr-app-commands::
|
|
:zephyr-app: samples/hello_world
