hello,

I have little question about dump for atmega eeprom.

I have d1-d3.bin from working orinal cable and I know that these files contains all information for atmega eeprom (cable licence) but I dont know how to put together.

Is there anybody who knows how to do that ?

thanks and sorry for my english

Hi to all!
I've just upgraded my "noname" clone from 704.1 to 908 with files from post 453 and it works.
Thank you for all the info that I found on this forum.

Because somehow ponyprog doesn't work with my STk500 Atmel programmer, I just used PonyProg, to split "dump file" in two separate files (FLASH and EEPROM). Than I used CodevisionAVR to programm the Atmel.

Another thing that I haven't found on the forum is, that my type of clone has programming connections already routed to the side of the PCB, so I just had to solder some pins to the holes and did not have to perform any soldering at Atmel pins (shown on Images below).

I believe your PCB was the first versions made in Europe and not in China.

You're a lucky guy because you have a very good hardware

I am trying to get the EEPROM updated via modified d1-d3.bin files but I at the moment all my experiments were a failure.

I have a theory that if you have a cable with a FLASH that needs to be upgraded and with a blank EEPROM...

...if you have verified 10.6.x d1-d3.bin files the FLASH and EEPROM will be upgraded to the most recent FLASH and the EEPROM will be written with a valid dump for 10.6.x VCDS.

So, If someone here has the d1.bin, d2.bin and d3.bin for VCDS 10.6.x please share those files here.

What it is used file (VCDS_908.0_mod)?

Sorry? Are you answering to my last post about updating the EEPROM?

Please explain yourself again

4 wires soldered to atmega, shield of LPT cable conneted to GND of power supply (12V)...
Downloaded ponyProg200 2.07 (i think latest version) and:
Calibration OK....
but when trying to "read all" error -14 occurs, and when trying to "erase" error "-9" occurs...see attached picture...

so guys...where is the catch?

You need to change for AVR micro ATMEGA162

Thanks...but then i get this....

Maybe because:

1 - Your LPT cable isn't correct. Check the schematics again.

2 - You have short circuits in the thin wires that are connected to the ATMEGA. Recheck all connections with a multimeter.

3 - You haven't connected pin 25 of LPT port to GND.

4 - You haven't soldered the shield wire into the metallic part of the DB25 connector and then plug it into GND.

5 - You should try lower resistor. Try 820ohm, 680ohm, 560ohm, 470ohm, 390ohm... But, don't forget that those resistors are there to protect the LPT port, not the ATMEGA. Don't push the limits of the LPT port... so don't use resistors lower than 100ohm.

6 - Your LPT port is not set to ECP/EPP mode in BIOS.

Good Luck

Can anyone in here share de d1.bin, d2.bin and d3.bin files from a 10.6.x version?

Please share those files after you test you cable and the result is a "Fully Licenced / Activated" license.

Thanks.

I have read your previous posts and done those steps(only 6th didn't check)...but after pressing ignore i got message read successful...then i opened flash.hex from arash(i couldn't "erase" even by pressing ignore but could "flash" it but after 15mins i got "write failed" message

[cocutanu]

In my case step 6 did the trick !!!
Try it and you will be ready to go...unless your ATMEGA has a fuse set to "locked".
Good Luck

While changing from EPP to ECP...dont know exactly when...interface died...The LED does not turn any more...even with disconnected LPT..
Actually i have probably forgotten to disconnect it while(from PC and from 12V) i was restarting PC to get to BIOS...
i could choose in bios fro parallel port:
Output only
Bi-directional
EPP
ECP
So which one to choose? And how to check what went wrong?Stabilizer?

I have now found out that without connecting anything to LPT after pressing ignore i can read all and get "read successful" but nothing i written in it actually

croatiaobd - Yes, now you have dead atmega. Good luck
Kenshin, it's not gona work, stop waaste time.
