 +This demo is targeted towards the Texas Instruments LM3S6965 Ethernet evaluation kit, with 256 kB internal Flash EEPROM and 64 kB internal RAM.
  
 +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.

 +===== 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]].
-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) toolchainAlternatively,​ you can use the [[manual:demos:​gcc_arm_embedded|GCC ARM Embedded]] toolchain. +
