| To program the bootloader into the internal flash on the LM3S6965 microcontroller, the LM Flash Programmer utility was used in combination with the In-Circuit Debugger Interface (ICDI), that is available on the board. 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 LM3S6965 microcontroller, the LM Flash Programmer utility was used in combination with the In-Circuit Debugger Interface (ICDI), that is available on the board.

| + | ===== 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]]. | ||
