System Clock
|
|
============
|
|
|
|
The steval_fcu001v1 system clock can be driven by an internal or external oscillator,
|
|
as well as by the main PLL clock. By default, the system clock is driven by the PLL clock at 84MHz,
|
|
driven by a 16MHz high-speed external clock.
|
|
|
|
Serial Port
|
|
===========
|
|
|
|
The steval_fcu001v1 board has one UART. The Zephyr console output is assigned to UART1.
|
|
Default settings are 115200 8N1.
|
|
|
|
I2C
|
|
===
|
|
|
|
The steval_fcu001v1 board has one I2C. The default I2C mapping for Zephyr is:
|
|
|
|
- I2C2_SCL : PB10
|
|
- I2C2_SDA : PB3
|
|
|
|
Programming and Debugging
|
|
*************************
|
|
|
|
Applications for the ``steval_fcu001v1`` board configuration can be built and
|
|
flashed in the usual way (see :ref:`build_an_application` and
|
|
:ref:`application_run` for more details).
|
|
|
|
Flashing
|
|
========
|
|
|
|
Flashing Zephyr onto the steval_fcu001v1 board requires an external ST-LINK/V2-1 programmer.
|
|
The programmer is attached to the P8 programming header with ARM-JTAG-20-10-Plug-in Adapter.
|
|
|
|
Flashing an application to STEVAL_FCU001V1
|
|
------------------------------------------
|
|
|
|
Connect the FT232-to-USB port to host system, and RX, TX, Gnd pins to
|
|
the P7 header of the steval_fcu001v1 board. Then run a serial host
|
|
program to connect with your steval_fcu001v1 via the FT232 board:
|
|
|
|
.. code-block:: console
|
|
|
|
$ minicom -D /dev/ttyUSB0
|
|
|
|
Now build and flash an application. Here is an example for :ref:`hello_world`
|
|
|
|
.. zephyr-app-commands::
|
|
:zephyr-app: samples/hello_world
|
|
:board: steval_fcu001v1
|
|
:goals: build flash
|
|
|
|
You should see the following message on the console:
|
|
|
|
.. code-block:: console
|
|
|
|
Hello World! steval_fcu001v1
|
|
|
|
Debugging
|
|
=========
|
|
|
|
You can debug an application in the usual way. Here is an example for the
|
|
:ref:`hello_world` application.
|
|
|
|
.. zephyr-app-commands::
|
|
:zephyr-app: samples/hello_world
|
|
:board: steval_fcu001v1
|
|
:maybe-skip-config:
|
|
:goals: debug
