	Problem Reading EEPROM with ME7 EEPROM tool. « on: May 20, 2024, 02:52:00 PM »

I have a 2002 1.8T ECU ME7.5. I put it into bootmode and when i try to read the eeprom using the ME7 EEPROM tool i am getting this error.

Command: ME7EEPROM_st10 --bootmode 95080 -r -p3 --CSpin P4.7 dump.bin

Code:

ME7_EEPROM v1.40
COM: 3, Baud Rate: 10400
Memory type: 95040, size: 512
Chip Select pin: P4.1
Opening COM3 ... OK
Starting Boot_mode ... uC ID response 0xFF. Unknown ID. (error=0x40201)
Closing COM3

Your ecu has a 95040 eeprom to start, that would be the ID issue.

I tried that as well and it did not work

Hi, you are getting no Processor ID, can be anything from connection until ecu is not in boot mode. Are you grounding the boot pin on power on ?

Yes, I know that it's for sure tripping into bootmode.

I would try to verify connection in trying to connect without boot mode, just use vcds lite, nefmoto in obd mode or any other diagnose tool you have to hand and connect to the ecu.

It's connects fine using those methods.

you can try the open source tool and post full screen output:
http://nefariousmotorsports.com/forum/index.php?topic=18686.msg164642#msg164642
ME7BootEeprom 9600 -read -SSC 1 Port4 Pin7 512 eeprom.ori
ME7BootEeprom 9600 -write -SSC 1 Port4 Pin7 modified.bin

on read you can use decimal 512 or 0x100 as size indicator
