VAG-COM/VCDS EVERYTHING

[djcristi]

most china clone interfaces have protection ic, that will rewrite ftdi-eeprom content & atmega-eeprom content on every power up. so these cables cannot be damaged

I've treid to program the Atmega 162 with UPA, but I have a problem.

I've followed this guide from rsibiza:
"When using original UPAUSB there is a folder how to connect..wire up between upa and atmega...
U need an DB9 connector to solder some 6 wires as described in the folder i mentioned...for ATMEGA162
Best is powering up the atmega by upa also,no external supply...
Need first read fusebits from working one...if need,i can post how they should be...
*Erase flash erase eprom
*Open first eprom hex,close fusebits select
Atmega162 eeprom write
*Open flash hex,close fusebits select
Atmega162 flash write
Disconnect BD9 connector from upa,and power up by 12V the interface...check if led turns to green...Done"

At the end, the LED lit up green, so all seemed good. But still, VCDS says: "Cable not found error -1"

And when trying to read the Atmega with UPA I only get 000000 s.... (this may not be a problem), but eventhough I've programmed the fuse/lock bits, when reading them out, all says "false".

try program fusebits (CD, DC, F9) but not lockbits..
Lockbits = FF
You'll can read the atmega..

If after test you read some content like the flash and eeprom "dumps"..and fusebits are CD,DC,F9..the problem is in another part of VCDS... In device manager appear like Rosstech HEX+USB? Or appear like Rosstech DirectUSB?
If "direct usb"...is with RL and the procedure is different.
Look inside your interface, maybe must unsolder STC, reseter (or diode), R..

Can you upload photos with inside of VCSD? both sides of PCB.. But photos with good resolution.

It has the FT232BL, and it shows up as "ROSS TECH HEX or KEY USB interface"

Will check what you wrote about the fusebits, if that doesn't help I'll upload a pic of the inteface

...
nobody solved the issue related the VCDS with NEC uc?

For Rl based usbdriver you need also rewrite atf16v and make some more changes..see for 10.6 crappy interface mod

Look inside VCDS. Exist that STC? You must unsolder..3 components..

Hi, i have problem... Please somebody should dump Mprog (FT232BL) for 11.8 EN VCDS beta?

MProg ept file for any VCDS version is the same is the same.
Here it is the ept file for VCDS tools ( no metter what version it is )
Maybe you need more then this ( Atmega eeprom dump )
Good luck

ATF16V? Could you please tell me what should I do?

Here's my interface btw.:






Tried to program it with PonyProg today, but it says "device not responding"

[mishu_b]

....
your interface is with NEC uc not with Atmega.

how did you programmed this uC? and with which dump?

Misu don't you see that he said that he couldn't because it is NEC and he tried with PonyProg as for Atmega.
VTS_Tibi said: Tried to program it with PonyProg today, but it says "device not responding"
No dump for Nec and it is a chinese thing, I suppose it will not show up.
Good luck

How could you tell it's NEC?

[liviudiaconu]

Tibi...is first time when you write that cable?
Look on the picture..

[KenshinPT]

Well! Better than us you can check if it's ATMEGA or NEC.

However, if its NEC how can you use an ATMEGA dump and expect to work on the NEC uC?

I/O, fuses, timers, interrupts are totally different... You won't be able to get that NEC uC working...

However, I am thinking in something strange... Maybe chinese engies changed the LASER engraving of the ATMEGA to NEC... just to confuse us?

Why I suspect on that LASER changing? Welll... if Ross Tech doesn't have a VCDS cable with a NEC uC, how can someone adapt an ATMEGA dump to work in a NEC uC?

IMHO, It's impossible.
