I'm on my way to where the car is parked , trying the EEPROM reading after connecting the spare ECU in place of my original one.
I'll post the results.
Thanks for the info.

I Just read my spare ECU's EEPROM 95040 through OBD . IT worked like a charm and it took only 1.5 minutes, I want to mention that the ECU was not paired and it was read with ArgDub's tool after it was connected to the car without removing the cluster's fuse. After that with DDillenger -how to guide- I learned the SKC of the spare ECU and paired with my car cluster using VagCom. Everything went from the first time and all the procedure with the car running at the end with the spare ECU took less than 10 mins.
I thank you everybody , this is an awesome SITE.
Next that I have a spare working ECU is to write a new map in order to accomodate my supercharger to my NA engine without having DTC's and sustain a good fueling
Thanks ones again everybody for their input.

Okay guys, I can't figure out why this doesn't work. I've tried everthing.

I have 4 different cables, 1 Ross-Tech old-school HEX-COM interface. 3 different variants of blue and black vag-tacho-like interfaces.
The one I'm trying now is a blue one with a FT232RL chip.

Set up using COM 1, baud rate set to 115200 in Windows XP sp3 under VirtualBox.

I always get error 0x50001 without seeing any communication with the ECU.

The Ross-Tech cable communicates effortly via a prolific usb-serial adapter in this setup.

ANY pointers would be appreaciated!

Oh, the car in question is a 2003 Audi A4 1.8T engine code BFB (think european AMB).

Cheers!

Hello and thank you for the great tool.

I'm trying to get this to work bootmode on a 2005> Volvo ME7 ECU with 95080 flash chip.

I get the following:

Starting Boot_mode ... uC identification response = 0xD5. Not supported. (error=0x01)

Are there any other avenue that I can explore or am I stuck desoldering etc?

Many thanks..

Got it to read 100%! I assume writing will work but haven't tried.

Thanks to a friend who helped (rkam).

The bin file was a 1:1 match from the read I took with my chip programmer off-board.

Here is the console output if it helps anyone:

mind sharing how you got it to work :-D i went the old school method with mine, worked though, ofcourse i dont plan on frying my ecu again

edit : nvm, i read your commandline, thanks

noob question Embarrassed

but has anyone delt with error message boot_mode fail no echo from cable error=0x07? I am jumping pin 24 to ground via a switch I soldered from pin24 to the outer section of the PCB and if so what might be causing this issue? I have successfully read this ecu with my current cable and I am currently using version 1.31

I had this when I first used it yesterday, I updated the FTDI drivers from the site and set the cable to COM1 instead of 10 then rechecked my connections and it worked.

Not sure which one of those fixed it to be truthful.

Hi there,

I've got issues writing to my 95080, I can read fine which makes me think it's some sort of write protection?

When I use your exact same argument except I use 95P08 instead of 95080 and P6.3 instead of P8.2 I get: error: too many arguments specified...

If I use bootmode to try to read without the CSpin and P6.3 I get:
Starting Boot_mode... uC ID response 0X00. Unknown ID. (error=0x40201)
My chip is 95P08C3

If I try to do a bootmode write I get an error of: Invalid file size 'file.bin'. (error=0x3010C)

This in an a ME7.1.1 from a D3A8 and again the eeprom chip is 95P08C3
Here is a sample read I got from using a couple of various tools...
Any ideas Argdub?
And thank you for this wonderful tool

Hmm I just noticed something odd that may explain the write error.
On my computer the file shows as 1kb so I didn't think anything of it, but I just noticed that when I uploaded it to here it shows as 512. I took a pic of the chip on the board and it is indeed the 5P08C3.
Now i'm corn fused...

understood

Now please look at attached image and tell me if I am correct

So I am just trying to understand the checksum calculations. I know there is a utility to do it, but I want to know exactly how it works.

I understand 0xFFFF - (Sum of Octets) but that seems over simplified.

It looks like it is actually 0xFFFF - (Sum of Octets) - (row offset from 0x10)

The above is where 0x10 counts as the 0th row. This mostly makes sense to me but why is row 0x10 and 0x20 the same with a checksum offset by 1, but then rows 0x90 and 0xA0 are the same values as well but the checksums are exactly the same? Same thing with rows 0x70 and 0x80.
