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/
Run CMake passing the flag -DBOARD=<board_name> to configure the compilation scripts to your specific board hardware
cmake -DBOARD=<board_name>
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
First, make sure that the LPCXpresso path is set correctly inside <openMMC_root_folder>/CMakeLists.exe
set(LPCXPRESSO_PATH <lpcxpresso_path>)
NOTE: You can also use cmake-gui to set this option.
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.
