|
Pin Mapping
|
|
===========
|
|
|
|
FK7B0M1-VBT6 board has 5 GPIO controllers. These controllers are responsible for pin muxing,
|
|
input/output, pull-up, etc.

Default Zephyr Peripheral Mapping:
|
|
----------------------------------
|
|
|
|
The FK7B0M1-VBT6 board is configured as follows
|
|
|
|
- UART_1 TX/RX : PA9/PA10 (available on the header pins)
|
|
- User LED (blue) : PC1
|
|
- User PB : PC13
|
|
- SPI1 NCS/CLK/MISO/MOSI : PA15/PB3/PB4/PB5 (NOR Flash)
|
|
- QuadSPI NCS/CLK/IO0/IO1/IO2/IO3 : PB6/PB2/PD11/PD12/PE2/PD13 (NOR Flash)
|
|

|
System Clock
|
|
============
|
|
|
|
The FK7B0M1-VBT6 System Clock could 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 280MHz,
|
|
driven by an 25MHz external crystal oscillator.
|
|
|
|
Serial Port
|
|
===========
|
|
|
|
The Zephyr console output is assigned to UART1. The default communication settings are 115200 8N1.
|
|
|
|
Programming and Debugging
|
|
*************************
|
|
|
|
Applications for the ``fk7b0m1_vbt6`` 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 FK7B0M1-VBT6 board does not include an on-board debugger. As a result, it requires
|
|
an external debugger, such as ST-Link, for programming and debugging purposes.
|
|
|
|
The board provides header pins for the Serial Wire Debug (SWD) interface.
|
|
|
|
Flashing an application to FK7B0M1-VBT6
|
|
---------------------------------------
|
|
|
|
To begin, connect the ST-Link Debug Programmer to the FK7B0M1-VBT6 board using the SWD
|
|
interface. Next, connect the ST-Link to your host computer via a USB port.
|
|
Once this setup is complete, you can proceed to build and flash your application to the board
|
|
|
|
Here is an example for the :ref:`hello_world` application.
|
|
|
|
.. zephyr-app-commands::
|
|
:zephyr-app: samples/hello_world
|
|
:board: fk7b0m1_vbt6
|
|
:goals: build flash
|
|
|
|
Run a serial host program to connect with your board:
|
|
|
|
.. code-block:: console
|
|
|
|
$ minicom -D /dev/ttyACM0 -b 115200
|
|
|
|
Then, press the RESET button, you should see the following message:
|
|
|
|
.. code-block:: console
|
|
|
|
Hello World! fk7b0m1_vbt6
|
|
|
|
Debugging
|
|
=========
|
|
|
|
This current Zephyr port does not support debugging.
