The package which Eric and I maintain supports 3 types of BDM pods. The
Coldfire is the P&E type pod. For the 683xx the ICD P&E pod is
supported, as well as the 5 chip design (PD) which is documented in the
BDM package.

All pods are known to work and people have been active in providing good
patches. I know of only 2 outstanding patches which do not relate to

Hosts supported are FreeBSD and Linux in direct parallel port access,
and remote via the client/server interface.

On Windows, Win95 is supported and the Cybertec ftp site has a binary of
GDB and Insight.


The Insight is a little green but I could download and single step. 

The windows version can connect remotely to a Unix server. This is nice
for NT type users. I am yet to try and get the server work on Windows.

W2K and NT do not currently work directly accessing the parallel port
hardware. This is being worked on using a package called GiveIO. With
GiveIO I think the Win2K and NT version should become a reality.

While on the subject of BDM, if anyone is interested in flash
programming using BDM, a discussion about this happened the other day on
the Coldfire mailing list
