hi, I am trying to write to a 29ee010 chip with a GX 4x4 chip burner.

I cannot find the above chip type, the closet I find is 29F002 which is 256KB vs 128KB (The chip in the burner)

I decided to try and write to it anyway, i used HxD to verify and the parameters are way off. Could someone please point me in the right direction?

Below are relevant codes


Configuration OK!
This software is updated already.
ID check skipped
Reading... Buffer
Elapsed time: 7.32 seconds.
Read completed.

Elapsed time: 2.72 seconds.

Elapsed time: 7.34 seconds.

Please start a new thread for this. But short answer is thats a flash memory, not the traditional eeprom type we mostly use and being page erase your going to need the right memory mapping, close but not the same wont work.

This seems to be missing so I thought it would be good to add it as i had to search else where for it ...I did not read every post so apologies if this is a repeat.

PCM, Powertrain Control Module
BCM, Body Control Module
ECU, Electronic Control Unit, (generic term, ie. "Engine ECU")
ECM, Engine Control Module
TCM, Transmission Control Module
TDM, Theft Deterrent Module

please correct and delete if this info is wrong in any way .
Other wise it should be on the first page
