Hey guys,

Im embarrassed to write this,

i keep getting some version of the 0x01 unable to open comport error.

this is regardless of whether i use a vista netbook or a windows 8 desktop.
i have tried an ebay cable and a genuine ross tech cable
v1.31 in cmd and the gui v 1.5 same error

windows 8 wont allow me to assign the COM, but i know from looking its in port 8 hub 3.

i can assign it on the netbook and its in port1, same issue

haha obd or pin 24 boot mode

this is an a6 2.7t ecu with immo, its me7.1 bosch hardware.

please please please what am i doing wrong?!?

just downloaded all the new drivers from ross tech, it confirmed it is up to date.

in cycling back through my SH*T i realized i did not have 12v going to pin 21 on the ecu on my old harness (had only touched M, A and H box stuff till now)

that is updated and corrected.

is there a more specific VCP driver you are reffering too other than the current ross tech drivers that include VCP?

UPDATE:

restarted computer and now EEPROM driver is OK

Searching chip_Select pin fails (error + 0x70C01)


UPDATE again haha,

can read eeprom perfectly in OBD mode, reads and saves.

cannot read in boot, always gets hung up on the same bit.

here is the success:

ME7_EEPROM v1.40
COM: 1, Baud Rate: 10400

and here is the failure

ok so trace ze pins with a multimeter set to continuity mode

Just thought id add my 2cents from when i did this

i did an immo 2 ecu from a 1.8t golf and was getting this:

EEPROM Status:
- VIN: XXXXXXXXXXXXXXXXX
- SKC: 065535
- Immobiliser: On
- Checksum: OK
- Size: 512bytes
- Cluster Code: 00 00 00 00 00 00
- P0601 DTC: not set
- Immo ID: XXXXXXXXXXXXXX
- Softcoding ID: 11500

so i was sweating a bit but took the gamble had to turn the baud rate up to max but all good

its so much easier to knock up a bench loom than attempt it on the car imo.

Thanks for a great tool 

Error codes are all in ze code 

I can make a list if theres is must interest, the dev should have a nice header file though.

try 65535 and report back
