Hi,

I'm trying to virginise an Alfa 147 2.0 manual ECU (0 261 206 708) ME731HA002.

I've got it set up on a bench and read the EEPROM using the following:
ME7EEPROM.exe --bootmode 95080 -r -p3 --CSpin P4.7 orig.bin

C:\alfa>ME7EEPROM.exe --bootmode 95080 -r -p3 --CSpin P4.7 orig.bin
ME7_EEPROM v1.40
COM: 3, Baud Rate: 10400
Memory type: 95080, size: 1024
Chip Select pin: P4.7
Opening COM3 ... OK
Starting Boot_mode ... uC ID response 0xC5: C167CR ... OK
Sending Loader + MonitorCore ... MonitorCore successfully launched
Initializing registers ... OK
Sending EEPROM driver ... OK
Configuring SPI Interface ... OK
Checking EEPROM Status Register ... 0x0080
Reading EEPROM ... OK
File saved
Closing COM3

I've altered the orig file to virginise it:
50 & 60 orig:
FF FF C0 48 45 D9 7B 25 25 FF 7F 84 57 50 5F 06
FF FF C0 48 45 D9 7B 25 25 FF 7F 84 57 50 5F 06
to:
FF FF C0 48 45 D9 7B 25 DA FF 7F 84 57 50 AA 05
FF FF C0 48 45 D9 7B 25 DA FF 7F 84 57 50 AA 05

I then write the file using the following:
C:\alfa>ME7EEPROM.exe --bootmode 95080 -w -p3 --CSpin P4.7 virgin.bin
ME7_EEPROM v1.40
COM: 3, Baud Rate: 10400
Memory type: 95080, size: 1024
Chip Select pin: P4.7
Opening COM3 ... OK
Starting Boot_mode ... uC ID response 0xC5: C167CR ... OK
Sending Loader + MonitorCore ... MonitorCore successfully launched
Initializing registers ... OK
Sending EEPROM driver ... OK
Configuring SPI Interface ... OK
Checking EEPROM Status Register ... 0x0080
Writing EEPROM ..OK
Closing COM3

After writing, I power down/up the ECU and read the file as in the first step. The problem is that the file I now read is identical to the orig - it hasn't changed.

Any help would be greatly appreciated.
