System Clock

The WB2 (BL602) Development Board is configured to run at max speed (192MHz).

Serial Port

The ai_m62_12f board uses UART0 as default serial port. It is connected to USB Serial converter and port is used for both program and console.

Programming and Debugging

Samples

#. Build the Zephyr kernel and the Hello World sample application:

# From the root of the zephyr repository
west build -b ai_m62_12f samples/hello_world
west flash

Run your favorite terminal program to listen for output. Under Linux the terminal should be /dev/ttyUSB0. For example:
```
$ screen /dev/ttyUSB0 115200
```
The -o option tells minicom not to send the modem initialization string. Connection should be configured as follows:
- Speed: 115200
- Data: 8 bits
- Parity: None
- Stop bits: 1
Then, press and release RST button
```
*** Booting Zephyr OS build v4.2.0 ***
Hello World! ai_m62_12f/bl616c50q2i
```

Congratulations, you have ai_m62_12f configured and running Zephyr.
