I have created a no-nonsense skeleton project you can use with the AVR32 GNU Build toolchain, without having to use the AVR32 Software Framework.

The project includes:

  1. A Makefile geared for the AT32UC3B1256 Microcontroller (as on the Copper development board)
  2. The needed trampoline code (for JTAG and other use)
  3. The needed linker script for the microcontroller
  4. Generation of the .elf and .hex images

To add more source files to the project, simply append to the OBJECTS line in the Makefile.

You can grab the Git repository from Gitorious:
