Hello. Today I am working with an older Transmission controller.
This also has 90 pin motorola header like the 411.
From the top side of the board with CPU, it is a mirror image of the connector.
I can deal with holding 12v on flash and all of that if need be. For now I just want basics to work.
So far I can not enter BDM mode on Processor. With oscilloscope I can see BKPT being held low from normal 3.x voltage. Maybe Hold BKPT low to gnd with a jumper? Any problem just holding it low while testing?
Motorola 68332 Target

I read the Motorola manual some and I see that BRKPT needs to be held low, but it must happen on the rising edge of the reset signal. I will attempt to get reset set up on channel 2 today and watch and see if timing is correct.
What other things should I look for that would keep it from entering BDM?
