Programming STM32-Discovery using GNU tools. Linker script

Previously we went through setting up a development environment for ARM Cortex-M3 microcontroller. We decided that two equal choices will do the same job – either CodeSourcery G++ Lite or Yagarto. Both use the same base of GNU tool-set. Developing with GCC tools To get a working binary, there is a series of tools involved during code development. Several tools are necessary to compile simple applications. These are compiler, assembler, linker and binary generator. Each of them does its task in a chain process. When you start compiling your project, usually there is a linker invoked, which with correct parameters links libraries, object files. Once executable is generated, then the binary image generator creates a binary image (.bin or .hex) that can be uploaded to MCU. We won’t go into… Continue reading
