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:

  1. Checkout the stm32flash tool’s code from the repository.

$ git clone http://git.code.sf.net/p/stm32flash/code stm32flash
$ cd stm32flash

  1. Build the stm32flash tool.

$ make

  1. 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.

  1. Connect the serial cable to the UEXT lines of the UART interface (pin #3=TX and pin #4=RX).

  2. Power the OLIMEXINO-STM32 via the mini USB.

  3. Reset the board while holding the button (BUT).

  4. 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

  5. Run your favorite terminal program to listen for output.

    $ minicom -D /dev/ttyUSB0 -b 115200

    The -b option sets baud rate ignoring the value from config.

  6. 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.
