|
.. warning:: The +5V pins on this board are directly connected to the +5V pin
|
|
of the USB connector. There is no protection in place. Do not
|
|
power this board through USB and an external power supply at
|
|
the same time.

|
|
|
|
.. note:: CAN feature requires CAN transceiver.
|
|
Zephyr default configuration uses CAN_2 exclusively, as
|
|
simultaneous use of CAN_1 and CAN_2 is not yet supported.
|
|
|
|
Other hardware features are not yet supported on Zephyr porting.
|
|
|
|
The default configuration can be found in
|
|
:zephyr_file:`boards/others/black_f407ve/black_f407ve_defconfig`
|
|
|
|
|
|
Pin Mapping
|
|
===========
|
|
|
|
BLACK_F407VE has 5 GPIO controllers. These controllers are responsible for pin
|
|
muxing, input/output, pull-up, etc.

System Clock
|
|
============
|
|
|
|
BLACK_F407VE System Clock could be driven by internal or external oscillator,
|
|
as well as main PLL clock. By default System clock is driven by PLL clock
|
|
at 168MHz, driven by 8MHz high speed external clock.
|
|
|
|
Serial Port
|
|
===========
|
|
|
|
BLACK_F407VE has up to 6 UARTs. The Zephyr console output is assigned to UART1.
|
|
Default settings are 115200 8N1.
|
|
Please note that ST-Link Virtual Com Port is not wired to chip serial port.
|
|
In order to enable console output you should use a serial cable and connect
|
|
it to UART1 pins (PA9/PA10).
|
|
|
|
|
|
Programming and Debugging
|
|
*************************
|
|
|
|
Applications for the ``black_f407ve`` board configuration can be built and
|
|
flashed in the usual way (see :ref:`build_an_application` and
|
|
:ref:`application_run` for more details).
|
|
|
|
Flashing
|
|
========
|
|
|
|
BLACK_F407VE board includes an ST-LINK/V2 embedded debug tool interface.
|
|
This interface is supported by the openocd version included in Zephyr SDK.
|
|
|
|
Flashing an application to BLACK_F407VE
|
|
---------------------------------------
|
|
|
|
Here is an example for the :zephyr:code-sample:`blinky` application.
|
|
|
|
Run a serial host program to connect with your board:
|
|
|
|
.. code-block:: console
|
|
|
|
$ minicom -D /dev/ttyACM0
|
|
|
|
Build and flash the application:
|
|
|
|
.. zephyr-app-commands::
|
|
:zephyr-app: samples/basic/blinky
|
|
:board: black_f407ve
|
|
:goals: build flash
|
|
|
|
You should see user led "LD1" blinking.
|
|
|
|
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: black_f407ve
|
|
:maybe-skip-config:
|
|
:goals: debug
