Programming and Debugging
Flashing an application
Connect your device to your host computer using the JLINK USB port. The sample application Hello World is used for this example. Build the Zephyr kernel and application, then flash it to the device:
# From the root of the zephyr repository
west build -b apollo3_evb samples/hello_world
west flash
Note
west flash requires SEGGER J-Link software and pylink Python module to be installed on you host computer.
Open a serial terminal (minicom, putty, etc.) with the following settings:
Speed: 115200
Data: 8 bits
Parity: None
Stop bits: 1
Reset the board and you should be able to see on the corresponding Serial Port the following message:
Hello World! apollo3_evb
