Setting ARM GCC development environment

As we mentioned before, we are going to stick with free software tools. So we are going to use free and open-source GCC compiler to develop programs for ARM Cortex microcontrollers. As we will work from the windows environment, there are a couple of serious choices that are pretty similar. One is using CodeSourcery Lite edition or Yagarto Gnu ARM toolchain. Both tools work the same as they use the same GCC compiler and other tools. Both seem to be supported frequently. CodeSourcery claims that they are updating Lite Edition twice a year, while Yagarto is doing this more regularly depending on updates of separate tools. So your choice won’t affect your final result. When installed you can quickly check if everything works fine by opening command-line tool and writing a simple command that checks the version of ARM GCC compiler: arm-none-eabi-gcc.exe -v Both can be used with Eclipse IDE and require a makefile. The only difference – is a path to tools when compiling. Download any or both of these and install to your machine. Next step is to… Continue reading
