Everything is tested on Mac OS X at the moment only with the LPC1768 mbed devices. As soon as i get other devices, i will integrate the other processors and vendors too. If you like too have additional targets added you can either send:
- a pull request with the needed addition
- a board, i will add support as soon as possible
Install the gcc-arm toolchain
Download the gcc-arm-embedded toolchain
Unpack the file in /opt/local
tar zxvf ~/Downloads/gcc-arm-none-eabi-4_8-2013q4-20131218-mac.tar.bz2
- Create a symbolic link, so it is easy to switch between different toolchain versions
ln -s gcc-arm-none-eabi-4_8-2013q4/ gcc-arm
- Add the gcc-arm-toolset to your path
Get and build mbed libraries
- Clone the mbed libraries to /opt/local
git clone https://github.com/mbedmicro/mbed.git
- Build the needed mbed (depending on your board and your compiler) libs with
python ./workspace_tools/build.py -r -e -u -d -m LPC1768 -t GCC_ARM python ./workspace_tools/build.py -u -d -m LPC11U24 -t GCC_ARM
I always build for some other targets too (to see how the path settings differ for creating useful variables).
python ./workspace_tools/build.py -r -d -m RBLAB_NRF51822 -t GCC_ARM python ./workspace_tools/build.py -r -e -u -d -m K64F -t GCC_ARM
- Run the mbed tests, you have to choose the correct settings for the Volume and the serial port
python ./workspace_tools/make.py -c -v -m LPC1768 -t GCC_ARM -d /Volumes/MBED -s /dev/cu.usbmodem1442 -p 0
Test if mbed-cmake works for you
- Get a clone of cmake-mbed
git clone https://github.com/uwearzt/mbed-cmake.git
- Build the blinking LEDexample with cmake. If you have installed the gcc-arm or the mbed libs to another directory, you have to set the path to them inside arm_mbed.cmake.
cd build cmake .. make make upload <reset> make sercon
and you should have a blinking LED and a serial console with some up counting lines.
Integrate into your own project
The best way to integrate cmake-mbed is to use it as a git submodule. In your project repository do
git submodule add https://github.com/uwearzt/mbed-cmake.git mbed-cmake git submodule init git add .gitmodules mbed-cmake cp mbed-cmake/CMakeLists.txt .
and do the necessary changes in the CMakeLists.txt. With cmake ist is always a good idea to create a build directory as a subfolder and do out-of-tree builds. The best way to ignore all the intermediate files is a .gitignore with * inside the build folder.
mkdir build echo "*" > build/.gitignore git add -f build/.gitignore
