System Clock
The FK7B0M1-VBT6 System Clock could be driven by an internal or external oscillator, as well as by the main PLL clock. By default the system clock is driven by the PLL clock at 280MHz, driven by an 25MHz external crystal oscillator.
Serial Port
The Zephyr console output is assigned to UART1. The default communication settings are 115200 8N1.
Programming and Debugging
The FK7B0M1-VBT6 board does not include an on-board debugger. As a result, it requires an external debugger, such as ST-Link, for programming and debugging purposes.
The board provides header pins for the Serial Wire Debug (SWD) interface.
Flashing
To begin, connect the ST-Link Debug Programmer to the FK7B0M1-VBT6 board using the SWD interface. Next, connect the ST-Link to your host computer via a USB port. Once this setup is complete, you can proceed to build and flash your application to the board
Here is an example for the Hello World application.
# From the root of the zephyr repository
west build -b fk7b0m1_vbt6 samples/hello_world
west flash
Run a serial host program to connect with your board:
$ minicom -D /dev/ttyACM0 -b 115200
Then, press the RESET button, you should see the following message:
Hello World! fk7b0m1_vbt6
Debugging
This current Zephyr port does not support debugging.
