Open Source modular IPM Controller firmware

The following packages are needed in your system in order to compile the firmware:

• gcc-arm-none-eabi
• cmake
• cmake-gui (Optional)

gcc-arm-none-eabi can be installed from the pre-compiled files found at: https://launchpad.net/gcc-arm-embedded/+download or you can run the following command under Ubuntu:

sudo apt-get install gcc-arm-none-eabi

Next step is to clone this repository into your workspace.

git clone https://github.com/lnls-dig/openMMC

Go to the repository folder

cd /path/to/repo/

If this is the first time compiling this firmware, run CMake configuration scripts

cmake .

You can set your board options in the file build_cfg/config.cmake. You can change the Controller, Board name, version and select which modules you want to be included in your compilation.

After changing the desired options, run the CMake configuration command again (the CMakeCache file will not be edited by this command) and compile the firmware:

make -s

NOTE: The compiler will return several warnings, most of them are regarding the LPCOpen libraries and do not affect the library functionality.

Both a .axf file and a .bin file will be generated in the out folder. You can use any one you prefer to program your processor.

To clean the compilation files (binaries, objects and dependence files), just run

make clean

If you own a LPCLink board, you can use it to program the LPC1764 processor via its JTAG interface

To transfer only the application firmware, run

make program_app

To transfer only the bootloader firmware, run

make program_boot

If you want to erase the whole Flash and copy both firmwares:

make program_all

NOTE: In this case you must have the LPCXpresso installed in your machine, since we need to use some initialization scripts that they provide. NOTE 2: We only have linker scripts to LPC1764, so if you wish to compile to a different target, you'll have to change the linker\lpc1764_boot.ld and linker\lpc1764_app.ld files, which defines the memory regions, otherwise you'll run into some HardFault errors.
