You need to provide clear picture of the board. Much clear than the one you posted.

The pic does not show what kind of CPU. The current BDM NT support MC6833X CPU. If it is different CPU then you need another tool to program it.

This is C166 core. The current BDM NT and JTAG NT does not support this board.
If we have enough interest and it is possible to add support to it. But looks like it is a very old CPU.

Alright, hopefully people will support this thread and let see the way out toward. If you do not, I can have one unit ship to you for research

I am currently working on MPC850 CPU. There are a lot of ECU that uses MPC55X which is the same family.
Hope soon we can support MPC based ECU.
