+
+	* Press debugging button and enjoy your debugging journey.
+
+![](doc/3-1-8-atmel-start-Studio7-start-debugging1.png)
+
+		* Debugging start and you can add breakpoint.
+
+![](doc/3-1-8-atmel-start-Studio7-start-debugging2.png)
+
+		* Debugging paused at breakpoint and you can monitor local variables at Watch window.
+
+![](doc/3-1-8-atmel-start-Studio7-start-debugging3.png)
+
+
+# 4. Reconfigure MCU BSP
+
+	* Visit <https://start.atmel.com/#> and upload project configuration.
+
+![](doc/4-1-1-atmel-start-Studio7-reimport-project.png)
+
+	* Now you can reconfigure your project.
