-====== Upgrading from Codesourcery G++ Lite to the GCC ARM Embedded toolchain ====== 
- 
-===== Background ===== 
-For several years Codesourcery (now Mentor Graphics) maintained and released the GCC for ARM compiler binaries, bundled with an easy to use installer, under the name Codesourcery G++ Lite. Unfortunately,​ their website now states that "​Sourcery CodeBench Lite releases for ARM EABI, ARM GNU/Linux, ARM AARCH64-Linux,​ IA32/IA64 GNU/Linux and ELF are no longer available"​. 
- 
-Fortunately,​ the ARM organization itself is actively maintaining and enhancing the GCC compiler for the ARM architecture. At regular intervals they release pre-built binaries of the toolchain under the name [[https://​launchpad.net/​gcc-arm-embedded|GCC ARM Embedded]]. ​ 
- 
-Several OpenBLT demo programs that target microcontrollers with an ARM core, make use of the Codesourcery G++ Lite toolchain. You can still find a download link to a working version of the toolchain on the page that describes the demo specifics. However, is it recommended to switch to the GCC ARM Embedded toolchain. ​ 
- 
-This page describes how to upgrade from the Codesourcery G++ Lite to the GCC ARM Embedded toolchain, to the point that you can build the OpenBLT demo programs without any further changes. 
- 
-===== Upgrade procedure ===== 
- 
-==== Step 1 - Uninstall Codesourcery G++ Lite ==== 
-Open your Windows Explorer and browse to directory //​C:​\Users\{username}\MentorGraphics\Sourcery_CodeBench_Lite_for_ARM_EABI\uninstall\//​ and double-click the program //​uninstall.exe//​. 
- 
-==== Step 2 - Download and install GCC ARM Embedded ==== 
-Visit the [[https://​launchpad.net/​gcc-arm-embedded|GCC ARM Embedded]] website and download the Windows installer. The filename is something like //​gcc-arm-none-eabi-5_3-2016q1-20160330-win32.exe//,​ although the version number and release date in the filename might be different. 
- 
-Starts the installation by double-clicking the file you just downloaded. You can use all the default settings of the installer, except on the last screen. Here you need to check the checkbox //Add path to environmental variable//, as can be seen in the following illustration:​ 
- 
-{{:​manual:​demos:​gcc_arm_install_with_path.png?​}} 
- 
-At the end of the installation,​ the readme-file is shown and a command prompt window is opened. Both can be closed. 
- 
-==== Step 3 - Download and install make and rm ==== 
-The build environment of the OpenBLT demo programs, which are configured for Codesourcery G++ Lite, rely on the utilities GNU make and rm that automatically get installed with Codesourcery G++ Lite. Now that these utilities are no longer on your computer, they should be downloaded and installed again. ​ 
- 
-Download the utilities by following thes link {{:​manual:​demos:​gnu_build_tools_win32.zip|}}. Once download, unpack the zip-archive and copy all unpacked files to the //.\bin// directory of where GCC ARM Embedded was installed. It will be a directory similar to //​C:​\Program Files\GNU Tools ARM Embedded\5.3 2016q1\bin//​. 
- 
-This completes the upgrade procedure. Refer back to the page that describes the specifics of the [[manual:​demos|OpenBLT demos]] and follow the instructions for building the bootloader and demo user program.
