Yaris ECU Reverse Engineering Progress

[Nexus1155]

ok since my blog got deleted with this info in it, i just figured it would be easy to keep up with it by starting a thread....If anyone wants to help, they will get recognition and of course perks...



The picture is high res enough that you can see all of the serial numbers and everything, but none of those help to tell what kind of processor this is.

As you can see there are a couple of sets of rows on the bottom left hand corner of the board..The 16 pin one with the holes is a COP connector. The 20 lead one on the left i believe is a ARM connector.

I just purchased a wiggler that should be able to connect with both of these interfaces. but as you can see the supposed 20 ARM (JTAG)connector is directly interfacing with the processor, so i beleive i should try and go for that first.



theres only twelve, because there are about 9 grounds on the line itself, but i needed something that can interface with current software without having to dev my own...

I'll leave it at this for now, and keep adding stuff as i find it...
