System Clock
OLIMEX-STM32-E407 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-E407 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.
If you have an external JTAG probe compliant with the default Zephyr OpenOCD
configuration, however, then applications for the olimex_stm32_e407 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-E407
Connect the ST-Link USB dongle to your host computer and to the JTAG port of the OLIMEX-STM32-E407 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_e407 samples/hello_world
west flash
Run a serial host program to connect with your board:
$ minicom -D /dev/ttyACM0
After resetting the board, you should see the following message:
***** BOOTING ZEPHYR OS v1.8.99 - BUILD: May 29 2017 22:31:53 *****
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_e407 samples/hello_world
west debug
