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 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.

- | The demo programs are pre-configured for building with the {{:manual:arm-2013.11-24-arm-none-eabi.zip?linkonly|Codesourcery G++ Lite}} (Target OS EABI) toolchain. Alternatively, you can use the [[manual:demos:gcc_arm_embedded|GCC ARM Embedded]] toolchain. | + | 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. | ||

+ | 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]]. | ||
