Programming and Debugging
*************************
The BRD4001A includes an `J-Link`_ serial and debug adaptor built into the
board. The adaptor provides:
- A USB connection to the host computer, which exposes a debug interface and a
USB Serial Port.
- A physical UART connection which is relayed over interface USB Serial port.
- An Ethernet connection to support remote debugging.
It is compatible with the following host debug tools:
- :ref:`openocd-debug-host-tools`
- :ref:`jlink-debug-host-tools`
OpenOCD is included in the Zephyr SDK. Refer to the links above for information
on how to install required host debug tools if you are not using the Zephyr SDK.
Flashing
========
Connect the BRD4001A main board with the mounted radio module to your host
computer using the USB port.
Following example shows how to build the :ref:`hello_world` application for
BRD4104A radio module.
.. zephyr-app-commands::
:zephyr-app: samples/hello_world
:board: efr32_radio_brd4104a
:goals: flash
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 see the following message in the terminal:
.. code-block:: console
