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.
Flashing an application to the Olimex-STM32-E407¶
The sample application Hello World is being used in this tutorial. To build the Zephyr kernel and application, enter:
$ cd <zephyr_root_path>
$ source zephyr-env.sh
$ cd $ZEPHYR_BASE/samples/hello_world/
$ make BOARD=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, enter the following command:
$ make BOARD=olimex_stm32_e407 flash
Run a serial host program to connect with your board:
$ minicom -D /dev/ttyACM0
After reseting the board you should see the following message:
***** BOOTING ZEPHYR OS v1.8.99 - BUILD: May 29 2017 22:31:53 *****
Hello World! arm
