Updating Atmega162 VCDS and other interfaces

[rsibiza]

Hi Guys.

Here i wanna continue something i allready started one time,and hope it will be alive some more time.

Explaining how to update,upgrade a VCDS interface,or other tools using Atmega162.

What should you know about the atmega162?

It may possible that reading flash an eprom from it is locked by FUSES...so if your atmega is locked by LOCKFUSE...only an external paralel programmer can reset this FUSE by High Voltage Paralel Programming (HVPP)...you should unsolder atmega162 from PCB before doing HVPP,because normally your atmega and components runs 3-5 volt...HVPP uses 12-13,5 V to programm and can damage components on PCB.

Here 2 different Interfaces,which i used to erase/reset FUSES

[onomaepitheto]

very good tutorial

[rsibiza]

Wiring up the Atmega.

Simpliest way to flash atmega is ISP programming,you can use ISP6 or ISP10 pinheader interfaces.

I use normally the USBASP Programmer from:

USBASP AVR Programmer - $16.00 (http://www.protostack.com/index.php?main_page=product_info&cPath=23&products_id=24)

it has ISP10 connector...

For correct connection,you need on atmega
MOSI pin1 on atmega pin1 on USBASP
MISO pin2............... pin9
VCC pin6................. pin2
GND pin16 .............. pin4
RESET pin4.............. pin5
SCK pin3 ................ pin7

If you try read or write atmega162 off PCB,you will need add an 7,2 mhz clock between Pin 14-15,XTAL1 and XTAL2...without clock you will be unable to connect to atmega...

You can also choose other clock rating(1MHZ) but atmega wont work properly inside vcds interface...as it is connected to 7,2...

[rsibiza]

In the attached Word document,you can check how to use Khazama,to write flash and eprom to atmega162 for use in VCDS interface.

If you connect correct,and atmega is recognised correct and you have trouble writing it,uncheck in write options all cases,and do step by step by yourself.



Set Fuses and Lockbits....write Fuses and Lockbits
Load eprom data,write eprom data
Load flash data,write Flash data
Verify Flash
Verify Eprom

To be sure always start by Command: read chipsignature

If you cant read:

Maybee SPIEN FUSE is not set,can be done only by HVPP
You missed correct wiring up
Offboard need to add Clock to XTAL1

[rsibiza]

Here a pic of a TQFP44 to DIP and ISP6 ISP10

I bought it from Virtual Village...but was crap.
Needet to cut 5 tracks and change way by wires to do correct switch from TQFP to DIP and be able programming on paralell programmer.

On HVPP and External paralell Programmer no need for clock to XTAL1

[rsibiza]

I really apreciate Khazama to write Atmega162,but sometimes on different atmega...khazama fails...on board..in this case i often use the extremeburner...which clearly can be used with same programmer as explained some posts before...unplug USBASP replug open extremeburner and try again...as explained in attach.

hello, is it possible to update the china vcds with this methode

[rsibiza]

hello, is it possible to update the china vcds with this methode


Yes. The original one makes update only by USB,after installing new updated vcds.

[jarripote]

Very good!!, thank you very much

[rsibiza]

This "interface" can be built by everybody himself at Home,and be used on old PC with Paralell Port(DB25) together with Ponyprog software.

Ponyprog is freeware.

But i prefer USB Programmers


When you have no connection,try decrementing resistors until 0... The resistors are not for protecting Atmega....they are there for protecting Paralell Port...so check all wires if everything fine before powering up.

[potel]

What should you know about the atmega162?

It may possible that reading flash an eprom from it is locked by FUSES...so if your atmega is locked by LOCKFUSE...only an external paralel programmer can reset this FUSE by High Voltage Paralel Programming (HVPP)...

This process might ruin the content of flash and eeprom also, right?
Tell me I'm wrong, please!

[bladezz]

Good!!, thank you

[rsibiza]

Tell me I'm wrong, please!


On External Paralell programmer,you normally can enable SPIEN Fuse without destroying flash and eeprom content,if LOCKFUSES are not set.

If LOCKFUSES are set,you need first erase entire memory in flash and eprom before enabling SPIEN is possible.

But depending on programmer,checked FUSE can be enabled or disabled...you need check the bit...

[zoro1]

If the lock are present yоu mast erase flash and eeprom.Is the *.hex file for the Atmega available?

[potel]

...depending on programmer,checked FUSE can be enabled or disabled...you need check the bit...

Can you please 'elaborate' a bit on it? That might be VERY interesting (and not at all offtopic).
Have you particularly managed to program fuses (e.g. EESAV) on a locked atmega without destroying content of eeprom area? Could be possible?
Thank you.

Thank you.

If the ATMEGA is locked you can't read the content of the EEPROM.

If you want to reset fuses the content of EEPROM will also be erased.

To do this fuse reset and EEPROM erase you need to dessolde the uC from the PCB and then connect it to a HVP (High Voltage Programmer) thus the content of the memory is lost.

You can read the content of the EEPROM if you have a laser to destroy the uC case and then with a microscope you can read the content of the memory bit by bit. Then you need a pen and a paper to write it down.

Yes,and no...

First hack is the invasive attack...destroying some atmegas...by laser or some acid burning the housing

But it seems,actually somebody has managed to create an external programmer able to confuse atmega lockbits...and read entire flash and eprom....by non ivasive attack...:congrats:

Atmega would not be destroyed....

Yes, it's possible to read locked atmega with special programmer. Even that atmage stays alive.

[potel]

Yes, it's possible to read locked atmega with special programmer.
Yeahhh.... :trytofly:Go on! Don't stop here!
Give us a hint... a track... WHICH PROGRAMMER ??? :listen:

[ipejasinovic]

Don't know. One of my friends have it and I know that he can unlock ATmega 8, 16, 64, 128 and 162. For other I didn't ask. But, don't forget, programming and reading AVR mcu's is his job. I doubt that he will give the name and source of programmer just like that.

Yes...why should he loose lot of money?...for not even a thank you:hmmmm2:thats the world today....

If i had infos about non invasive attacks for avr...


I know some chins asking more than 900 USD for reading one only avr...so how much need you to pay getting infos about hardware and firmware to do it yourself...

Let them do a good job..and hope that they continue doing it...

[tehnosoftex]

I think that all microcontrollers are sensitive to oscillator spikes or variations. As we can see there is programers which read protected motorola , micronas or even fujitsu. May be for atmel or pic can be made a such programmer but need some research to do.

You are right...in the document i posted before..are some instructions...but not great stuff...

What do we know...we need some powersource which can vary power peaks from 3 to 13 V...
how many variations/second?

Some fischls programmer:

fischl.de - USBasp - USB programmer for Atmel AVR controllers (http://www.fischl.de/usbasp/)

But need some one able to write a great FW for it...check which power or oscillation peakes and changes where needet

[zoro1]

Yes, it's possible to read locked atmega with special programmer. Even that atmage stays alive.

If the fuse bit is set to 0xFC ,even God can not read Atmega with programmer.The China-man clones the ELM 327/a PIC microcontroler/with Grinding mashine and a electron microscope

[rsibiza]

Thats what atmel and they user are wanting,but not completely thrue.

All avr or pic can be attacked...by power glitch,peakes oscillo peakes...it looses control...and let read the content.

Grininding,laser and electron microscope is also very successfull,but not only choice.

[tehnosoftex]

I know that for secure microcontrollers, like these used in smart cards , there is a sensor which apply reset on mcu core when sense variations in oscillator frequency. Why they do that?

Hello,
With this program has to run wires if you do it as a LPT port?, enough to power the usb programmer?

[rsibiza]

If u use a LPT port u have to connect gnd to lpt port,but nee external 5 volt and ground to power up the atmega.

In worst case,use an old usb cable,connected to pc it will have 5 volt on one on one gnd,the other 2 wires u can just cut away.

[xk1rk]

OK, thanks I have a USB ASP but I can not weld the pins on Atmega....I do not know soldering with tin solder...:motz:

Programmer Boards STK500 and STK600 is HVPP programming original from atmel. its around 200 - 250 euro .
STK500 not manufacturing anymore, i have bought it 5 years ago , now i think only STK600 can be found.
Can reset any kind of fuses from ATMEGAS and can programm all of their atmegas.
Its a good think to have in house.

[cipijoint]

and for everybody who really wants to learn AVR programming ( atmel ) can sign up on the best forum in the world for that.
AVR Freaks (http://www.avrfreaks.net/) .
Its everyting about atmel can be leanrt there, from simple programmers schematics home made to real programming knowledges.
just take your time.
I learnt there everyting about that :champions:since many years ago.

This is very informative thanks.

Lockfuses are not set,i suppose you use it for your own,not for selling purpose,so no need of saving your stored data...

[liviudiaconu]

I understand. But, the problem is that with fuse like in document the vcds don't work. if i don't write the fuses, vcds work fine. (for this i must erase atmega with ponyprog and set ALL fuses and bits unactivated in ponyprog).

For me works just fine,but no problem.

Write fuse and lockbits with pony,so your interface will work,then read fuse and lockbits with khazama or extremeburner save them and all will be fine.

Anyway i also encoured some errors last time...using khazama,and now i use more extremeburner...lot more reliable i think,but not write all...khazama and extremeburner work better if first write only fuse/lockbits then flash and last eprom one by one...

If i choose write all i get errors also...

Well, with pony i write flash and eeprom and the last, fuses and bits. never errors. with kazama and extremeburner, without fuses and bits, ok, with them, not ok.

Try write fuses by pony and read with extremeburn...you will have the right one;)

[mattydr67]

@liviudiaconu
m8 don't waist your time. use what you know better, i mean use ponyprog and forget about other programmer.
you know and you write Atmega's with it ok, and with the USB programmer you bloked an Atmega so till have a High voltage programmer to try please don't waist your time ask here. No one will answear you the right way.
Ok you can do like rsibiza said but forget about that.
The short way is the way you know not the stright ahead way.
You know what I mean.
Good luck

ok, i understand. ponyprog use lpt (to me on the notebook without com or lpt native=lpt programmer+pcmcia/lpt). usb programmer ib little and not need nothing else

Original tool's have bootloader inside..
That is why you update - flash via serial port ...
And AVR can be readed if they lock 100% , little harder then PicMicro but can noninvasive with programmer modified for that need's....

Can you give some directions how to do that? In which way to modify the programmer? It need to modify vcc , frequency or both?

No my friend, let me show how the things works.
liviudiaconu asked rsibiza how he can set the security bits in Khazama programmer or in the Extremeburner programmer becasue he use an USB programmer for Atmega162.
In tthe rsibiza tutorial about how to programm atmega with this kind of programmer using that two softwear, he set the security bits in a way but if you want to read then the atmega you can.
Now it is not a problem liviudiaconu fix that incovenience by himself. Not problem now.
I understand rsibiza why he is just half with us and please my friend don't complain about him because he had and he still has a good contribution in this forum.
It was a confusion and now everything is fine. rsibiza didn't tell him how to set the security bits but this was a usefull because he make us to think and sometimes when u use your brain you can fix everything.
So good luck guys and thanks to you my friend bibkare and also thanks to you rsibiza for your contribution in this forum.

For ISP for sure there is one error...Clock is missing from Xtal1 to Xtal2 ;)

The clock is only not needet for HVPP,but noone do it from UPAUSB,khazama or extremeburner:beer:

Yes you have the point. The Clock is missing. See my schema.

Should I add the capacitor also like originally on the VCDS pcb? I mean those two 22pf capacitor which you can see on second picture.

Thanks.

Not necesary,just add the clock as i told...and u will see it work...

Only if SPIEN Fuse is disabled...u will have no luck:beer:

Hi,

Thanks with clock I was able to program the Atmega. But when I solder it back I get "Short to 12V" on K2 line in VCDS. I used an external power supply. I checked the soldering and it's ok. Also the software shows me "Activated" but I think something is wrong with the Cable.

Do you have any idea what can be the problem?

I used Extremeburner. I noticed that the Calibration bit is FFFFFF51 instead of FFFFFF56. If I want to write the correct bit it always go back to FFFFFF51.

Thanks in Advance!

What i didnt get,is why u unsolder atmega to solder on other pcb..just solder 4 wires power up over obd connector and flash..

Unsolder the 4 diodes and check them..off pcb..just to be sure..

The noninvasive glitchs clock when it goes to check if its locked or not, each micro the timming for instructions are different it takes alot of time to figure everything out. Its cheaper paying them the 600 to 20,000 dollars.

Its possible programing Atmega 162 with UPA

[mexanico1971]

yes is possible !
I"m using upa ori but always give me bad mosi 3,64V don"t know why !

[cagatay87]

yes is possible !

try to change jumper on upa

[dimitar]

yes is possible !

Thats because upa is amateur crap

[szogun0]

You're wrong mate.
Upa is good enough for Atmega 162, operator can't do programming properly.

[vali2017]

very good tutorial
Thanks

Hello!!! Help is needed. I'm posting VAG COM 15.7.0 from China with ATMEGA162 + 16V8B + FT232RL. Chinese non-renewable sends Eng. version 15.7.0 . How to combine this wire with the updates , or even be a Russian VCDS? How to do it all . It is necessary to fill in the firmware ? As you do this ?
