Overview
|
||
|
|
********
|
||
|
|
|
||
|
|
Zephyr applications use the olimex_stm32_p405 board configuration
|
||
|
|
to run on the OLIMEX-STM32-P405 open source hardware. It is based on
|
||
|
|
the STMicroelectronics STM32F405RG ARM Cortex-M4 CPU.

System Clock
|
||
|
|
============
|
||
|
|
|
||
|
|
OLIMEX-STM32-P405 has two external oscillators. The frequency of
|
||
|
|
the slow clock is 32.768 kHz. The frequency of the main clock
|
||
|
|
is 8 MHz. The processor can setup HSE to drive the master clock,
|
||
|
|
which can be set as high as 168 MHz.
|
||
|
|
|
||
|
|
Programming and Debugging
|
||
|
|
*************************
|
||
|
|
The OLIMEX-STM32-P405 board does not include an embedded debug tool
|
||
|
|
interface. You will need to use ST tools or an external JTAG probe.
|
||
|
|
In the following examples a ST-Link V2 USB dongle is used.
|
||
|
|
|
||
|
|
Flashing an application to the Olimex-STM32-P405
|
||
|
|
================================================
|
||
|
|
|
||
|
|
The sample application :ref:`hello_world` is being used in this tutorial. To
|
||
|
|
build the Zephyr kernel and application, enter:
|
||
|
|
|
||
|
|
.. code-block:: console
|
||
|
|
|
||
|
|
$ cd <zephyr_root_path>
|
||
|
|
$ source zephyr-env.sh
|
||
|
|
$ cd $ZEPHYR_BASE/samples/hello_world/
|
||
|
|
$ make BOARD=olimex_stm32_p405
|
||
|
|
|
||
|
|
Connect the ST-Link USB dongle to your host computer and to the JTAG port of
|
||
|
|
the OLIMEX-STM32-P405 board.
|
||
|
|
Then, enter the following command:
|
||
|
|
|
||
|
|
.. code-block:: console
|
||
|
|
|
||
|
|
$ make BOARD=olimex_stm32_p405 flash
|
||
|
|
|
||
|
|
Run a serial host program to connect with your board:
|
||
|
|
|
||
|
|
.. code-block:: console
|
||
|
|
|
||
|
|
$ minicom -D /dev/ttyACM0
|
||
|
|
|
||
|
|
After reseting the board you should see the following message:
|
||
|
|
|
||
|
|
.. code-block:: console
|
||
|
|
|
||
|
|

||
|
|
|

|
|
Debugging
|
||
|
|
=========
|
||
|
|
|
||
|
|
Access gdb with the following make command:
|
||
|
|
|
||
|
|
.. code-block:: console
|
||
|
|
|
||
|
|
$ make BOARD=olimex_stm32_p405 debug
