The GNU development tool suite used by RTEMS supports most +modern CPU families. Often all that is required is to add RTEMS +configurations for the target CPU family. RTEMS targets for the GNU tools +usually start life as little more than aliases for existing embedded +configurations. At this point in time, ELF is supported on most of the +CPU families with a tool target of the form CPU-elf. If this target is +not supported by all of the GNU tools, then it will be necessary to +determine the configuration that makes the best starting point regardless +of the target object format. + +Porting and retargetting the GNU tools is beyond the scope of this manual. +The best advice that can be offered is to look at the existing RTEMS +targets in the tool source and use that as a guideline. + |
