+Reset Button
+________________________
+
+There are two holes on the breakout board that allow access to the onboard FPGA reset button and status LED.
+The reset hole is located just below the 'Digital Out' marking, and can be used to access the reset button on the onboard FPGA by inserting a thin wire or pin.
+The onboard FPGA status can be inspected by looking into the status LED hole.

+     Connecting or disconnecting the breakout board while the PC is on causes damage to the FMChost.
+
+#. Power off the PC to which the breakout board is connected.
+
+#. Disconnect the breakout board from the PC by disconnecting the digital and analog I/O grey SDR cable.
+
+#. Connect a USB-microUSB from the PC you will use to perform the firmware update to the Config port on the side of the breakout board.
+
+#. Verify the Breakout Board version by looking at the specifications on the product.

+
+   .. warning::
+         Make sure that the host firmware image you download matches the Breakout Board hardware version
+         you verified in the previous step. An incorrect firmware version will not report any error while updating but will cause failures during operation.
+
+#. Download the :ref:`breakout_updater_download` utilities package and unzip
+   it. Navigate to this folder using a console. Place the firmware image you downloaded in the previous step in the same folder.
+
+#. Press the onboard FPGA reset button (using a thin tool that fits the reset hole) to put the device into bootloader mode. The onboard FPGA status LED will breathe to indicate it is ready to be programmed.
