I'm not sure if this forum is the correct place to talk about reverse engineering, but I like this topic so let's see if I can help.
My understanding is that the presence of a BDM connector will be highly dependent on the ECU manufacturer. I have no experience operating a BDM interface, either, but I do believe that this is the appropriate interface for the MC68376. If you're lucky the pins will already be on the PCB. Be careful; I've heard that in some cases the pin labels are inverted compared to a standard BDM interface (if such a thing exists).
More pertinent is the possible identification of the flash memory chip that could be on the ECU circuit board. Have you opened up the ECU to look at all of the components?
What is your motivation and your end goal?
Thanks Obeisance.
Sorry for post in this Forum . I don't know where i can post my question .
Yes in board pcb there is BDM output , i must see if there are pin inverted i see normal motorola BDM output 5+ 5 pin .
In board there are 1 flash eprom 29f040b and one 128Kx8 SRAM and one 93c86
You ask why i need read this CPU?
I repair ECU for engine and sametime problem are in the driver and sametime problem are in a MC68376 are not good not working or became hot with with excessive power consumption. So i need change it with new , problem are because no more new ECU are avaiable because the ECU factory was closed so i ask if i can read working CPU and change Cpu in a not working ECU.
thanks
