System Clock

OLIMEX-STM32-H407 has two external oscillators. The frequency of the slow clock is 32.768 kHz. The frequency of the main clock is 12 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-H407 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 the Olimex ARM-USB-OCD-H is used.

If you have an external JTAG probe compliant with the default Zephyr OpenOCD configuration, however, then applications for the olimex_stm32_h407 board configuration can be built and flashed in the usual way (see Building an Application and Run an Application for more details).

Flashing an application to the Olimex-STM32-H407

Connect the ARM-USB-OCD-H debugger to your host computer and to the JTAG port of the OLIMEX-STM32-H407 board. Then build and flash an application.

Here is an example for the Hello World application.

# From the root of the zephyr repository
west build -b olimex_stm32_h407 samples/hello_world
west flash

Run a serial host program to connect with your board:

$ minicom -D /dev/ttyUSB0

After resetting the board, you should see the following message:

***** BOOTING ZEPHYR OS v1.11.0 - BUILD: Mar 12 2018 03:12:40 *****
Hello World! arm

Debugging

Provided that you have a JTAG probe, you can debug an application in the usual way. Here is an example for the Hello World application.

# From the root of the zephyr repository
west build -b olimex_stm32_h407 samples/hello_world
west debug
