@section MC683xx BDM Support for GDB

Eric Norum (eric@@skatter.usask.ca) wrote a driver for a parallel
port interface to a BDM module.  He and Chris John (ccj@@acm.org)
have put together a package containing everything you need to
use this.  From the README: "This
package contains everything you need to be able to run GDB on
Linux and control a Motorola CPU32+ (68360) or Coldfire (5206) target
through a standard PC parallel port." Information on this is
available at the following URL:
http://www.calm.hw.ac.uk/davidf/coldfire/gdb-bdm-linux.htm.

The efi332 project has a home-built BDM module and gdb driver for 
Linux.  See http://egi332.eng.ohio-state.edu/efi332/hardware.html)
for details.

Huntsville Microsystems (HMI) has GDB support for their BDM module
available upon request.  It is also available from their ftp site:
ftp://ftp.hmi.com/pub/gdb

The Macraigor OCD BDM module has a driver for Linux
written by Gunter Magin (Gunter.Magin@@skil.camelot.de).

@section MPC8xx BDM Support for GDB

Christian Haan <chn@@intego.de> has written a driver for FreeBSD 
based for"a slightly changed ICD BDM module (because of changes
in the BDM interface on the PowerPC)" that "probably will work with
the PD module too."  His work is based on the M68K BDM work by
Gunter Magin (Gunter.Magin@@skil.camelot.de) and 
the PPC BDM for Linux work by Sergey Drazhnikov (swd@@agua.comptek.ru).
This is not yet publicly available.

Sergey Drazhnikov (swd@@agua.comptek.ru) has written a PPC BDM driver for
Linux.  Information is available at http://cyclone.parad.ru/ppcbdm.

GDB includes support for a set of primitives to support the Macraigor
Wiggler (OCD BDM).  Unfortunately, this requires the use of a
proprietary interface and is supported only on Windows.  This forces
one to use CYGWIN.  Reports are that this results in a slow
interface.  Scott Howard (http://www.objsw.com) has announced 
that support for the gdb+wiggler combination under DJGPP which should
run significantly faster.
