GNU-Toolchain for BCUs

The aim of the project is to port the GNU Binutils and GCC to the Freescale M68HC05 Microcontrollers and create other tools to support the programming of the EIB buscouplers (BCUs).

Other parts, like gdb, newlib or sim will be partially supported, to support automatic regression tests for GCC and to analyse fail regression tests.

The state is:

  • The GNU toolchain for m68hc05 is available.
  • GCC can run regression tests and fails for less than 1400 regression tests
  • The BCU SDK provides a development system and eib bus access.
  • More testing is needed to find all hidden bugs.

Current sources: m68hc05-gnu-0.0.1.tar.gz (~55MB)

To use the sources, extract the sources and run 

./configure --target=m68hc05 --enable-gdbtk=no --disable-newlib-io-float
make
make install

To get the changes for a newer version, do a diff between the origin and main branch of my GIT repository.

A sourcefoure.net project is also available.
