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.
Serial Port
OLIMEXINO-STM32 board has up to 3 U(S)ARTs. The Zephyr console output is assigned to USART1. Default settings are 115200 8N1.
SPI
OLIMEXINO-STM32 board has up to 2 SPIs. The default SPI mapping for Zephyr is:
SPI1_NSS : PA4
SPI1_SCK : PA5
SPI1_MISO : PA6
SPI1_MOSI : PA7
I2C
The OLIMEXINO-STM32 board supports two I2C devices. The default I2C mapping for Zephyr is:
I2C1_SCL : PB6
I2C1_SDA : PB7
I2C2_SCL : PB10
I2C2_SDA : PB11
USB
OLIMEXINO-STM32 board has a USB 2.0 full-speed device interface available through its mini USB connector.
USB_DM : PA11
USB_DP : PA12
CAN
OLIMEXINO-STM32 board has a CAN interface with transceiver on board. CAN is accessible through a screw terminal.
CAN_RX : PB8
CAN_TX : PB9
Jumpers
The Zephyr kernel uses the OLIMEXINO-STM32 default jumper settings. Note that all jumpers on the board are SMD type. You will need to solder, unsolder, or cut them in order to reconfigure them.
The default jumper settings for the OLIMEXIMO-STM32E are:

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.
$ git clone http://git.code.sf.net/p/stm32flash/code stm32flash $ cd stm32flash
Build the stm32flash tool.
$ make
The resulting binary is available at
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 the Button sample application.
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).
To build the application and flash it, enter:
# From the root of the zephyr repository west build -b olimexino_stm32 samples/basic/button west flash
Run your favorite terminal program to listen for output.
$ minicom -D /dev/ttyUSB0 -b 115200
The
-boption sets baud rate ignoring the value from config.Press the Reset button and you should see the output of button application in your terminal. The state of the BUT button’s GPIO line is monitored and printed to the serial console. When the input button gets pressed, the interrupt handler prints information about this event along with its timestamp.
Note
Make sure your terminal program is closed before flashing the binary image, or it will interfere with the flashing process.
