OLIMEXINO-STM32
###############
Overview
********
Zephyr applications use the olimexino_stm32 board configuration
to run on the OLIMEXINO-STM32 open source hardware. It provides
support for the ST STM32F103RB ARM Cortex-M3 CPU and the
following devices:
* :abbr:`NVIC (Nested Vectored Interrupt Controller)`
* :abbr:`SYSTICK (System Tick System Clock)`
* UART
* GPIO
More information about the board can be found at the
`OLIMEXINO-STM32 website`_. The `ST STM32F103xB Datasheet`_
contains the processor's information and the datasheet.

System Clock
************
OLIMEXINO-STM32 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 72 MHz.
Jumpers
*******
The Zephyr kernel uses the OLIMEXINO-STM32 default jumper
settings.
The default jumper settings for the OLIMEXIMO-STM32E are:
+---------------+------------+---------------+
| Jumper Name | Open | Close |
+===============+============+===============+
| LED1_E | | x |
+---------------+------------+---------------+
| LED2_E | | x |
+---------------+------------+---------------+
| D23_E | x | |
+---------------+------------+---------------+
| R-T | x | |
+---------------+------------+---------------+
| P10_E | | x |
+---------------+------------+---------------+
+---------------+------------+---------------+
| Jumper Name | D10 | D4 |
+===============+============+===============+
| D10/D4 | | x |

Flashing Zephyr onto OLIMEXINO-STM32
************************************
Flashing the Zephyr kernel onto OLIMEXINO-STM32 requires the
`stm32flash tool`_.
Building stm32flash command line tool
=====================================
To build the stm32flash tool, follow the steps below:
#. Checkout the stm32flash tool's code from the repository.
.. code-block:: console
$ git clone http://git.code.sf.net/p/stm32flash/code stm32flash
$ cd stm32flash
#. Build the stm32flash tool.
.. code-block:: console
$ make
#. The resulting binary is available at :file:`stm32flash`.
Flashing an Application to OLIMEXINO-STM32
==========================================
To upload an application to the OLIMEXINO-STM32 board a TTL(3.3V)
serial adapter is required. This tutorial uses sample application
button :file:`$ZEPHYR_BASE/samples/drivers/button`.
#. To build the Zephyr kernel, enter:
.. code-block:: console
$ cd $ZEPHYR_BASE
$ make -C samples/drivers/button BOARD=olimexino_stm32
#. Connect the serial cable to the UEXT lines of the UART
interface (pin #3=TX and pin #4=RX).
#. Power the OLIMEXINO-STM32 via the mini USB.
#. Reset the board while holding the button (BUT).
#. Flash the application using the stm32flash tool:
.. code-block:: console
$ cd samples/drivers/button
$ stm32flash -w outdir/zephyr.bin -v -g 0x0 <tty_device>
Replace :code:`<tty_device>` with the port where the board
OLIMEXINO-STM32 can be found. For example, under Linux,
:code:`/dev/ttyUSB0`.
#. Run your favorite terminal program to listen for output.
.. code-block:: console
$ minicom -D /dev/ttyUSB0 -b 115200
The :option:`-b` option sets baudrate ignoring the value
from config.
#. Press the Reset button and you should see the output of
button application in your terminal.
.. note::
Make sure your terminal program is closed before flashing
the binary image, or it will interfere with the flashing
process.
