Samples

Build the Zephyr kernel and the Hello World sample application:

# From the root of the zephyr repository
west build -b aipi_eyes_s2 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
```
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 v4.4.0 ***
Hello World! aipi_eyes_s2/bl618m05q2i
```

Congratulations, you have aipi_eyes_s2 configured and running Zephyr.
