I am trying to setup the tools for debugging and ARM-Cortex M3 microcontroller using Eclipse. I have the project laid out with a custom Makefile and if I build it by simply calling make in the project directory, everything compiles; I flash the binary and it works.
Now, the Makefile uses CodeSourcery Lite tools and explicitly calls for arm-none-eabi-gcc, arm-none-eabi-ld etc. I installed them to /opt/CodeSourcery and modified the PATH so that:
Just my two cents, when the installer for CodeSourcery runs, it usually defaulted to the /home/<user>/ directory. Not sure if that is what's keeping the toolchain from being discovered by Eclipse. Might want to try a remove, then reinstall of the CodeSourcery toolchain, this time in the /home/<user>/ directory.
