Write by eobd with file read in bdm

[pippo65]

Hello all,I wanted to know if it is possible to write by obd with Galletto, a file read in bdm, but always with the Cock.
Thanks.

I think it is almost always possible, I often do it, on the bosch group, fiat edc16c39, edc16c34, lower siemens, then you have to see case by case, you try it, evil that goes with the resume is always in the bdm.

Sure you can do it, if it is edc16 you can write directly, if it is marelli 6jf also, if it is marelli 6f3 you have to first merge the files of the micro 513 kB with that of the flash, 2048 kB getting a file that is 2.5 MB, and then you can write.

Not all ecu's are read completely from the obd. And this is also true of some edc16 type the VAG

I say all that,I have to write the file to flash, 2048 kb read in bdm ecu NEVERTHELESS, 6F3 my G. Point
on another Marelli 6F3 of a friend by a plug-in obd with galletto v 54.
Everything here.

Perhaps you have not read his request, he spoke not of reading but you can write to a file read in bdm, via obd.
All files edc16 read in bdm can be written in the obd without any modification, however, the opposite can't do it, because in the serial read only the area of the maps.

For the marelli 6f3 instead, the discourse changes, the cock shall not only accepts the file to 2048 kB of flash, but it wants a file that is 2.5 MB, which you get simply joining in with the ecm or with any hex-editor the file that is read by the micro more the flash.

If the file obd and bdm are different, I prefer not to venture to write in obd a file that is structurally different from what I'd read in the obd. It is better to read from the obd, edit, and write.

Hello Matthew,I don't understand the last part of your speech,because you say that the rooster does not accept the flash file from 2048 on the Marelli 6F3?
I've always written alone and no problem.

Update: File written by obd with Galletto,no problem!!!
Thank you all for the answers.

[pippo65]

Usually the cock on the 6f3 accepts only one file, 2.5 MB, just trying to upload a file from 2048 kB resistent media gives you the error, probably the Grandepunto be the exception.

I'll give you a tip born from experiences of personal, marelli, are a bit special, you lock up easily during writing from the obd, especially with the cockerel v54 (this is the most terrible of the clones), if you don't have a specific tool write them always in the bdm and you're comfortable.

Ok Matthew,in the future I will follow your precious advice.
Now I have to put in a good effort and try to understand something with the maps
Thanks and to the next.
