This seems like it should be straight forward, but I cannot get past that alert.

What I've done and tried thus far.

1. Have the eBay Galletto cable and accompanying software disc.

2. Using the current FTDI drivers since I cannot get the system to remove them so I can try to install older drivers.  On an alternate computer I installed the cable with a 2005 era FTDI driver, but the software wouldn't communicate with the car at all.  Got a different alert for that one.

3. Printed out the instructions on AZ and followed it step by step; acc. off, ground to Pin 24, acc. on 2-3 sec, remove wire from ground, etc.

4. I've tried a ground wire to the bolt at the top of the strut, my trickle charger is happy using it as a ground, and it is picky about where I connect it, so I think that is good.  I also tried running a wire to the battery negative terminal.

5. Tried two different ECU's, same results each time.

6. I've tried starting the software, then doing the ground/acc. stuff following the software prompt.  Done the ground/acc. before starting the software and just hit ok at the prompts.

At this point I don't know what else to try.  Any suggestions?  This is all on a 2.7T S4.

What pins have you got connected on your ECU ?

I have found in the past that if i have not connected pin 62 (12v) I could not get into bootmode.

I always ground pin 24 then apply power to the ecu then press read and dont remove the ground until it starts the read ,this works for me.

I'm trying to connect with the ECU in the car.

If I leave the ground wire attached and hit ok on the software I still get the prompt that "Boot Mode Not Active".

The other prompt I get, when using the WinXP install with the older FTDI (2005) drivers, is "Opening Port Impossible".

are you trying to read or write to the ecu

Does your galletto id the ecu.

if you are reading the ecu have you tried in normal mode ie Benzina (your model) .

IMO this isn't a good idea... read the datasheet for the CPU. The bootmode pin only has to be grounded for a short time during power up.

this is probably 5 seconds max (how long is a short time ? )

nyet ,I am not saying you are wrong just what works for me no problems so far.

I have found that sometimes less time grounded and it will not allow bootmode ,

I dont know why, maybe the cheap hardware/software not detecting the change correctly and just saying bootmode not active .

But in the end has never lets me down .

I've had some ME7.1.x ECUs that were a pain to get into boot mode. Some required the removal of a resistor to do it. The ME7.5 ECUs I have tried always go into boot mode easily though.

Hey, whatever works, works :)

Just saying, "bootmode" is something the CPU goes into, and shouldn't be a function of whatever software you are using to connect to it.

Since this is happening to me with two different ECU's I don't think it is a case of a difficult ECU.

I don't have any problems connecting with the Nefmoto software, but I'd like to know I can connect with the Galletto cable if the need arises.

Shouldn't have to run a wire anywhere... try tweezers where the switch is in this picture

Using tweezers didn't lead to success.

I'm using the following driver version for the USB Serial Port and USB Serial Converter, FTDI 2.8.14.0 dated 3/18/2011.

I press ECU Data, sometimes I will try entering boot mode before pressing this, other times I'll press ECU Data and then follow the prompt:

The display says: "DATA READING"  "START DATA READING..."

The following alert box pops up:
"Attention Before To Continue: Remove the Fuse No 11, Put IL PIN 24 FLASH EPROM to MASS, GIVE FEEDING AND REMOVE TO MASS PIN 24 FLASH, END TO CONTINUE"

Follow instructions if I haven't already tried to enter boot mode, then Press Ok

Display Says: "BOOT MODE INACTIVE"

Alert box pops up:
"TURN 10 SEC OFF AND TURN ON THE DASHBOARD WAIT 10 SEC BEFORE OF CONTINUE"

Press Ok on that after cycling power and I seem to end the program at that point.

I've had similar problems be a result of a driver conflict. In my case it was a conflict with the APR Cheetah cable driver. Even if I removed the driver I could not get it to work. I tried a few different machines and it wasn't until I tried a fresh virtual machine that it worked.

I know you said you tried it on an alternate computer, but did that computer ever have any other cable drivers installed? Do you have access to a computer that has never had any flashing software or cable drivers installed?

I tried creating a virtual machine and that is where I got the "Opening Port Impossible" message.  I'm puzzled by that since I've created an alternate virtual machine from which I can get the "Boot Mode Inactive" prompt, but that VM uses the more current FTDI driver and has had the blue cable installed for use with Nefmoto.

I was thinking there might be a conflict, thus I created the clean VM.  It seems that something is missing from the new VM.  Perhaps I should try the latest FTDI drivers with it, since no other cable or software has yet been loaded.

Which drivers are the ones that come with your cable? The "recent" ones or the 2005 ones?

Here is a copy of the Galletto software & driver, maybe give that driver a try?

The drivers with the CD are the same as in that linked file.

If your PCB's layout match this one then you may need to remove this resistor to get boot mode to work. I have had ME7.1.x ECUs that won't go into boot mode until it is removed.

That doesn't appear to be an issue on either of the ECU's I'm messing with.

Would there be any reason to think I may have more success using the bench flash setup?  Separate power supply, wiring, etc.

I wouldn't think so, but who knows.

I still think it's a cable driver conflict or a problem with the Galletto cable driver. If possible, try installing the Galletto driver on a computer that has never had another cable driver installed on it.

I agree. Driver problem, not ECU problem.

Thanks for the suggestions, if I'm going to start spending a lot of time trying to find a possible solution it's nice to start off in the most likely direction.

Have you tried completely removing the ECU from power for an extended period (1hr+)?

I've had a couple of ECUs that won't go into boot mode unless they are disconnected from power for a while.  Then, if I mess up and miss boot mode on the first attempt after reconnecting to power I have to remove it from power again for an hour or so before I try again.

I had this issue. I ended up having to count to 10 after key on with the pin shorted to ground then releasing before it would go into boot mode. If it did not, it was a +12v removal completely then try again before it would work.

Greetings from Russia! :D

I'm a newbie in chip-tuning, trying to mess with ME 7.1.1 from a cayenne turbo (Bosch hw number is 0261207696).
For now I'm trying to back up the contents of 800bb (main) ROM. The main problem I'm currently having is: it simply won't go in bootmode (or so my Galletto 1260 clone reports). I've tried all kinds of bench harnesses:
http://wiki.obdtuning.com/images/0/03/VAG_ME_7_Skizze1.jpg - this one with "ignition switch" on pins 62/21, as some have suggested.
or the same one, but with switch on pin3 as others have said that's the proper way instead.
I tried a bigger resistor for the boot pin probe: 10K, tried a different ground point for the boot probe (alligator clamp on the ecu board, instead of the PSU ground).
Tried holding pin24 grounded for longer time (up to 10-15 seconds).
I even tried desoldering the bridge on the back of PCB: http://wiki.obdtuning.com/images/7/7f/VAG_ME_711_platine3.jpg

Nothing led to success, unfortunately.

So, trying to determine whether my Galletto is faulty: for how long should ME 7.1.1 stay in boot mode after it's triggered?
If I try checking the ECU with MPPS v12 clone, I can't connect to it for ~10-15 secs after I start the ECU up with pin 24 grounded. Does this mean that it actually goes in boot mode and then defaults to "normal operation"?

I also tried different PC, tried clean VM with WinXP, so I'm fairly sure it's not the software issue.

Also, I actually have a chip programmer for the 800bb, so the last resort would be to solder out the ROM and then solder it back, - but that's really a last resort.
Please help? :)


EDIT: Oh, I also tried reading ROM contents with the MPPS, but it somehow reads only 402 kilobytes out of 1Mb (I believe?) ROM, which is why I'm trying to do it in boot mode.
EDIT2: Just tried the following version of Galletto software: http://nefariousmotorsports.com/forum/index.php?topic=3088.0 with two different cables, still a no-go, - so the problem seems to be in the ECU itself. :( Anything else I can try?

EDIT3 (final?): So, apparently it's the problem with Galletto: MPPS v12 worked in boot mode. Setup that worked for me:
http://wiki.obdtuning.com/images/0/03/VAG_ME_7_Skizze1.jpg with "ignition switch" wired before pins 62/21. Also, resistor on the board's back is desoldered (should I put it in after I'm done?) - but I believe it could have worked prior to its removal.

The reason I can't get the whole 1Mb readout is because of the "noread" flag present in the firmware: MPPS software honors it, but there are ways to defeat it.

TL;DR version: Galletto is shit and doesn't work (maybe that's just me, though).

thought id share some thoughts/information since this got me very frusterated a while back..

i tried galletto myself, and yeah, the software works, but the GUI and translations are totally CRAP..!

i finally found out how to flash both eeprom and flash with this thing.. using either the galletto-cable OR a normal dumb blue "made in china" 232R cable after dissassembly and mod to the galletto binary.
(yeah, ONE cable for everything related to ME7, finally!)

so, i usually do bootmode while in the car, and what ive found works 110% is this:

1. ignition off
2. ground pin 24 on the ecu, preferrably from pin1 on the ecu connector.(main ECU ground)
3. turn ignition key on and after 3-4 seconds, release the ground from pin 24.

4. ecu should now be in bootmode according to the galletto software itself, AND probably everything you have ever read, including and all guides etc on the internet.. WRONG..!

5. turn the ignition key OFF and viola, you are now in bootmode and galletto, nefmoto bootmode and even the eeprom-tool works to both read and write.


this method have worked on every ecu i have ever encountered so far (20+ different me7.1, 7.5, 7.5.5 etc)

hope someone cares to try this  :)

i will say that my experience with galletto was ok, software and cable eventually did work after some tinkering like you said, but mine ended up starting to give me improper reads, then finally fried out of nowhere, i use mpps now for bootmode flashes, seems to be very consistent, and pretty fast if your in bench mode, am i reading your post right sn00k? i do have the software still, and a dumb blue cable, was the modification a pain?

id say the mod to use a normal "blue" dumb cable is quite easy.. requires a tool to read the correct ID from your cable, and then some tinkering.. perhaps not something to be discoussed here.. works like a charm tho.

There's a sticky about it. "galletto software edited with proper english" in the flashing/chipping section.

that is pretty nifty, thanks for the info

ah, its even posted here now, nice! :)

i guess cracking a software for a cloned hardware, to exchange with another cloned hardware, is ok..  ::)
