I'm a total newbie with disassembly and code. I am trying to understand how the computer in my truck works (Dodge Ram with 5.9 Cummins). I know the vehicle control module uses a Motorola MPC555 processor and I've found the documentation containing the memory map here: http://www.nxp.com/assets/documents/data/en/product-briefs/MPC555PB.pdf
I'm curious if i'm on the right track because when i load the flash file into IDA Pro I set the processor to a motorola cpu32 since my exact processor isn't listed and skip establishing a ram which I think is incorrect. IDA Pro also asks me to find the entry point of the bin which by this processor I assume is the reset vector address of 0x100 according to page 2:
Can you guys tell me if I'm way off here? Thanks for any help you can give me.
