Rebuilding mbed Libraries
The source code for the mbed library is open source and can be downloaded from the mbed mainline repository or the Micromint repository. To recompile it please follow these steps:
1. Install a compatible ARM toolchain. The mbed port for LPC4330 targets currently supports the Keil MDK, GCC ARM and GCC LPCXpresso toolchains. Firmware at Micromint is mostly developed using Keil MDK 4.73.
2. Install Python 2.7. The mbed build scripts are written in Python.
3. Install the mbed Library Sources. This includes full source code for all supported multiple microcontrollers and boards.
4. Edit workspace_tools/private_settings.py to reflect your toolchain directories.
from os.path import join armcc = "keil" ARM_PATH = "C:/Keil/ARM" ARM_BIN = join(ARM_PATH, "ARMCC", "bin") ARM_INC = join(ARM_PATH, "INC") ARM_LIB = join(ARM_PATH, "RV31", "LIB") GCC_ARM_PATH = "C:/Program Files (x86)/GNU Tools ARM Embedded/4.8 2014q2/bin" GCC_CR_PATH = "C:/nxp/LPCXpresso_7.5.0_254/lpcxpresso/tools/bin" IAR_PATH = "C:/Program Files (x86)/IAR Systems/Embedded Workbench 6.5/arm"
5. Compile the base mbed libraries. These are typical commands to change to the source directory, setup compiler environment and build the bootloader. Note that the Python directory in the PATH may be different in your development system.
cd mbed-master SET PATH=C:\Windows\system32;C:\Windows;C:\Python27 python workspace_tools/build.py -v -r -m LPC4330_M4 -t ARM > build.log python workspace_tools/build.py -v -r -m LPC4330_M4 -t GCC_ARM >> build.log
If your build is successful, the mbed libraries and headers for the LPC4330 M4 and M0 cores will be available in the ..\build directory. If not, check the build.log file.
