I have an ESZ Mercedes and it has MCU 9s12 (1L85D).

I have read it the eeprom and Flash, save it and after erased.
Now, the problem is I can not program the flash, only the Eeprom. Now flash area is only FFFFFFFFFFFFFFF.
I think is secured.
How can I unsecured the Flash for programing with the new dump?

Thank you.

If it is erased It will be FFFF s mate ... Why did you erase it ...?

You did Save the flash ... and it's a good dump...?

Post the dumps .....

Yes I saved the ori flash before.
I want to replace with a new flash and eeprom now, but doesn't work.
What should I do?

What are you using to Read/write it ....?

Why did you need to erase the flash? I assume from his answer mate .... wants to put in a different one ... (but fcuk knows why ).....

All the gold is in the eeprom though if you get what i mean.

Another thought mate ... MCU was from different application ... Therefore ... Flash different...mmmmmm

Flash is the same.
The problem is that Flash no more writing/ only reading.
I think Flash is secured now. I have to unsecured, but I don't know how.

Sorry mate ... never had that problem .. read /save/ erase / Write flash / write eeprom ...( you have checked that the Whole flash is empty) ...?Try doing it again ... with one of the other 128's... sorry can't be of more help .....(mmm thought .. Thats not the one you have to add 12v for Flash programming ) ...?

So you only needed to read/write the eeprom and save alot of trouble.
I thought ETL would sort this prob, im sure premierD will know.As he knows everything else LOL.

In which case do not use recycled content from xxx.bin and register in ETL extension and not enrolled in the BIN file which addresses should be entered in ETL sw and then normal to have a hex editor, all FF.

I have this problem.
You must use IN-Circuit mode.
Not on Target board for 9s12.
See pdf file from ETL for 9s12 device with 0l85d/1l85d maskset

3rd February, 2010, 03:21 PM
I tried In-Circuit with CAS3 and no result.
The flash is the problem /Eeprom I can read erase write as many time as I want only Onboard adaptor ETL. But Flash no write at all.

If a case did not simultaneously delete EEPROM and flash then the MCU is locked.Use manual of ETL for that mcu.Cheers.

as i see in your attached pic you didnt erase it before programming !!

for flash programming you must erase "aktivate" before programming.

I have erased before hundreds times and the same message after, even I have restarted the application.

Hey mate the solution is:

On board and program as 0L85D (DG128B)
works 100%
after that verify as 1L85D

Then you have an exception. Check document in ETL manual about 1L85D ( page 9 5.2.1).
The manual sais that you erase On Board and program in circuit.
there is no other way

One time I had EZS with 1l85D 80pin with erase Flash and Eeprom.
I try in-circuit programingwith ETL ,but don?t work.
then I try it with Skoda STREAM RADIO,
under LCD is second Mcu 1L85 80pin.
I change mcu with my from EZS, and program it without problem.
All was OK.
Try it program in other PCB not in original.

Why another board? just check if MOD A and MOD B is low. And the right frequency crystal/resonator is attached.

hi, m8, which tool you're using now to work with 9s12 ?

Just programmed a W230 EZS with same Mask.
I erased On board and programmed (flash and Eeprom) In circuit with BKGND and RESET pins lift up with ETL programmer.
Works OK

Just liftup pins ,resistor is not needed only if you use ECLK.

cammy25
8th February, 2010, 08:34 PM
Im sorry but i just read the whole thread :sleep::sleep::sleep:

I see you have a Rosfar R260.
You can recover the flash with it if you want.
It works in a different way as ETL and have a more effective way to enter flash with bootloader mode.

Tell me your MB part number and ill post the right flash so you can recover with rosfar.

vwpassat
8th February, 2010, 08:36 PM
Thanks all of you for your support.
Seem here, we are a great family.
I tried in-circuit and no results. I think I will give up and try another ESZ. I have head ache.

At least onboard I can read/write Eeprom (except flash) as many tine as I want.
But in circuit is worse: no Eeprom ,no Flash.

Noo m8
This dump is only for ETL format.
Rosfar needs other format:

Allpages of flash must be put after eachother.
And dump must be inverted (0=F 1=E etc etc)

here is a good flashdump and your eeprom dump.

just connect with rosfar then go to Eeprom editor.
Open Eeprom dump (as normal bin format) then write.
go to flash recovery and select the flashdump i gave you.

I forgot to ask you. Before to do this job with CAS3 do I have to erase MCU by ETL (Eeprom and Flash) and after that to solder it back on the ESZ?
Thank you.

NEVER GIVE UP

machines should listen to humans remember.

If you have good CAS3 (red case) you must connect.
The error means rosfar cant connect
in most cases Crystal is not ok or the 2x 22-27pF resonators are not ok.

vwpassat
9th February, 2010, 08:11 PM
Yes, maybe you right, CAS3 has blue case.
Sometime read MCU ESZ without any problem, and sometime not. Depends of mask.
I think ETL Onboard is more sure/ but I can not find any explanation at this case. Maybe MCU has been damage.
Before to erase, I read and saved the flash, after erase, no access for write anymore.

I had same problem with EZS W203 (w211-HC12), initially I tryed read/write using AK400, then tryed with Rosfar then I notice same case as screenshots you sent (vwpassat).
This evening I'll try desolder MCU to read write with ETL programmer: I'll keep you informed.

Could you confirm that on your EZS is mentioned (w211-HC12), could you send part number please (209 545 .. ..).

kanzus
23rd March, 2010, 03:09 PM
Pics in CAS_Result you sent means that Rosfar did not link MCU, so reading nor decoding is not possible.
Rosfar have to decode and bypass secu to read Flash and Eprom.
I had same problem, so I tryed to enter selecting all EZS in Mercedes Menu, I entered with "SL_W211_ST12 [R260]", then Rosfar link adnd decode, and got error message like " be carefull do not program" .. Click OK and open Eprom Editor:
select wright MCU, 1L85D is MC9S12Dx128 [R260], open File and select eprom in Rosfar Format, forget file you saved initially, choose sure and good file dump, then write eprom.

After that, close Rosfar application and disconnect usb, then reconnect usb and open Rosfar3000 application, choose Mercedes EZS E/C/CLK/SLK W211-ST12 [R260], click read, link and decoding is OK.
After that go to eprom editor and click "Recover Flash menu" select correct flash file dump (forget file you saved), and write --> Is it OK ??

I use Blue case Rosfar programmer, EZS is W211_ST12, there is QFP80 MCU, and connect wires : Black, red, violet, yellow, and of course Black and White BNC wires, as picture in Rosfar doc EZS ST-12 v1.

Hope it help mate !

Hi m8s.From my experience,I had two bad cases with 1l85D mcu,EZS W211.I worked programming in OBP mode.In the first case,mcu 1l85D;eeprom reading and writing OK but flash memory only reading.Second case;eeprom memory only reading,writing with many errors.Flash memory all OK,reading and writing.I can not remember,in one of two cases,with hot air I warmed this mcu and eeprom & flash successful programming.With second mcu,solutions was replacement with new 1l85D mcu.For this job,I used ETL 9s12 programmer but many times I use,successful,X-prog M programmer with ETL 9s12OBP adapter.Best regards.

the mcu have the problem?like 908 in laguna dash?when warm up work when cold stop or the programmer?someone else with original programmer or like smok tool or original xprog with this mask 1l85d read and right or have problem?what is good programmer with no problems because if i take clone r270 for 120 usd and have problem and i pay one ezs better to take smook tool for 9s12 and give 270 euro and work and safe with no problem.but and the original have problem?thanks
