RomRaider

Hello friends and Fenugrec! Thanks for the interesting project Nisprog, it works! It reads and writes firmware, but I cannot read Eeprom. I read in the instructions from the author that I need to find the address of the Eeprom function in the firmware and indicate it in Nisprog, but I can’t do that, I don’t know how to disassemble. Can anyone help me do this in a specific firmware 1jd16a? For some reason the NisRom program does not work for me and I cannot find the definition file for this firmware.

your ecu is a CMCB1PDM 1JD16A SH705520N?
Try 0x4571C
from https://nissanecu.miraheze.org/wiki/Eeprom_code some have different serial interface and pinouts ...
you will probably need to analyze your bin or zip and upload it here.

Use ghidra and get the bin loaded in code browser. Super H4 Big E. Dont analyze. Run the script nissan_load.py from nisutils and it will map out your memory so its not gibberish.
The scripts makes it easier but getting your bin loaded is still a sequence that maps accordingly. Definitions as well. You need ida for the rest of the scripts but it cost a grand or a torrent .
