There is two types of BDM interfaces. The old interface is used on
some microcontrollers like Coldfire V2 (MCF5272, MCF5282, etc) and
other (with less wires) used on Coldfire V1 (MCF51JM, etc) and HC(S)
uC.
How old are these CPUs?
What was the last release date of a CPU with a BDM protocol?
If these are CPUs firmly in the past, perhaps we should ignore them....
I think the newest ColdFire parts are from last year, I don't
know about the 8/16-bit MCU lines. They are by no means dead.
Do modern Coldfire/PowerPC CPUs use JTAG or BDM?
The big ColdFire parts use JTAG for boundary scan and BDM for debugging.
The new small, low-power parts seem to have only the new reduced-pin BDM
interface.
