Programming and Debugging
|
|
*************************
|
|
|
|
Applications for the ``nrf51_vbluno51`` board configuration can be
|
|
built and flashed in the usual way (see :ref:`build_an_application`
|
|
and :ref:`application_run` for more details).
|
|
|
|
Flashing
|
|
========
|
|
|
|
The VBLUno51 board has on-board DAPLink (CMSIS-DAP) interface for flashing and debugging.
|
|
You do not need any other programming device.
|
|
You only need to install pyOCD tool (https://pypi.python.org/pypi/pyOCD)
|
|
|
|
This tutorial uses the blinky application :ref:`blinky-sample`.
|
|
|
|
See the :ref:`getting_started` for general information on setting up
|
|
your development environment. Then build and flash the application in
|
|
the usual way.
|
|
|
|
.. zephyr-app-commands::
|
|
:zephyr-app: samples/basic/blinky
|
|
:board: nrf51_vbluno51
|
|
:goals: build flash
|
|
|
|
Debugging
|
|
=========
|
|
|
|
You can debug an application in the usual way. Here is an example for the
|
|
:ref:`blinky-sample` application.
|
|
|
|
.. zephyr-app-commands::
|
|
:zephyr-app: samples/basic/blinky
|
|
:board: nrf51_vbluno51
|
|
:maybe-skip-config:
|
|
:goals: debug
|
|
|
|
Testing the VBLUno51 with Zephyr: buttons, LEDs, UART, BLE
|
|
**********************************************************
|
|
|
|
Here are some sample applications that you can use to test different
|
|
components on the VBLUno51 board:
|
|
|
|
* :ref:`hello_world`
|
|
* :ref:`blinky-sample`
|
|
* :ref:`button-sample`
|
|
* :ref:`bluetooth-beacon-sample`
|
|
* :ref:`peripheral_hr`
