 To program the bootloader into the internal flash on the EFM32G880 microcontroller, the [[http://www.segger.com/development-tools.html|Segger J-Link]] JTAG interface was used. However, this is not required if you have another means of programming the internal flash.
-To compile the demo programs with [[http://www.mentor.com/embedded-software/sourcery-tools/sourcery-codebench/lite-edition|Codesourcery G++ Lite]] (Target OS EABI), you can invoke the make utility from the command line.
+To build the demo programs you can use the [[https://developer.arm.com/open-source/gnu-toolchain/gnu-rm|GNU ARM Embedded]] toolchain.
+===== Toolchain configuration =====
+The demo programs are configured for building with a Makefile. Before attempting to perform a build, update the location of the toolchain binaries (i.e. //arm-none-eabi-gcc//) in the Makefile. It is set in variable **TOOL_PATH**. If the toolchain binaries are available on the path, then the **TOOL_PATH** variable can be left empty.
+{{:manual:demos:makefile_toolpath.png?nolink&|}}
+It is assumed that tools such as GNU //make// and //rm// are installed and available on the path. For (Ubuntu) Linux users this can be achieved by running command: //sudo apt-get install build-essential//. Windows users can install the [[https://gnu-mcu-eclipse.github.io/windows-build-tools/|GNU MCU Eclipse Windows Build Tools]].
 ===== Building and programming the Bootloader =====
 Before the bootloader can be used, it needs to be built and programmed into the EFM32G880's internal flash memory. The steps in this section only need to be done once.
-Batch files are added to aid in building the software program. First clean the bootloader program by double-clicking the file "\Target\Demo\ARMCM3_EFM32_Olimex_EM32G880F128STK_GCC\**Boot**\cmd\**clean.bat**". Next, build the bootloader program by double-clicking the file "\Target\Demo\ARMCM3_EFM32_Olimex_EM32G880F128STK_GCC\**Boot**\cmd\**build.bat**". The output should look like:
+To build the bootloader, open a command prompt in directory **\Target\Demo\ARMCM3_EFM32_Olimex_EM32G880F128STK_GCC\Boot\** and run the command:
+<code>
+make clean all
+</code>
+The expected output is:

 The bootloader program is now ready to be programmed into the internal flash memory of the EFM32G880. Using your favorite programmer, flash the bootloader using one of the following files, depending on what file type your programmer supports:
-  * \Target\Demo\ARMCM3_EFM32_Olimex_EM32G880F128STK_GCC\**Boot**\bin\**openbtl_olimex_efm32g880.elf**

-===== Configuring Microboot =====
+===== Building the Demo Program =====
-The Microboot utility needs to be configured to connect to the correct COM-port and to communication at the correct baudrate:
-  * Start Microboot by double-clicking "\Host\**MicroBoot.exe**".
+To build the user program, open a command prompt in directory **\Target\Demo\ARMCM3_EFM32_Olimex_EM32G880F128STK_GCC\Prog\** and run the command:
-  * Click the "**Settings**"-button and select "**OpenBLT using UART**" from the dropdown box.
-  * Click the "**Options**"-button to configure the communication parameters.
-    * Select the PC's **COM-port** that the board is connected to.
-    * Set the baudrate to **9600** bits/sec.
-Once you saved the settings by clicking the "**OK**"-button twice, you can close Microboot by clicking the "**Cancel**"-button on the main screen. Microboot is now ready for action!
+<code>
+make clean all

+The expected output is:
