Welcome to the GNU Development chain for the Motorola 68HC11 & 68HC12 micro-controllers. The cross compiler works on any host supported by GNU tools (Solaris, GNU/Linux, FreeBSD, HP/UX, Windows,...).

The GNU Development Chain is very complete and integrates:

• The GNU C, C++, compiler (GCC 2.95.3 or GCC 3.0.4)
• The GNU Binutils 2.11.2 (as, ld, ar, objcopy, ...)
• The GNU Debugger (GDB 5.0, 5.1 or 5.2)
• The NEWLIB libraries (libc, libgloss, libm)

This development chain and the main components it is based on are distributed under the terms of the GNU Public License.

Release 1.1.1 is the latest stable release of this HC11/HC12 development chain.
It is available in source and binary forms for Linux and Windows.

Snapshot 20020626 is the latest development release (Beta release 1.9d).
It is available in source form and also in binary form for GNU/Linux and Windows only.
