disassemble a binary file ecu

[tranky]

I saw the tutorial and there may also be those of the bosch group.. from the video part by the letter I in the view of choice, therefore I assume but I'm not sure.
Staresa I can see better now I must get away from the parents (the snakes).
Have a good evening

[Errecinque]

Hey the two of you .....I, I look out the window for now. The hunger to know is so much.....but why haven't I listened to my mother and I have not studied in 20 years these things when I had the time and inclination to do instead of the university of the 3rd age in evening classes in his forum.

[tranky]

Hello Errecinque, approach the window that is cold!
You don't need a degree for these things.
I work from when I was 16anni and I don't even have a diploma.
Just a clear idea and the desire and time to learn and sight of your preparation and I guarantee you that you will be a guru in a very short time.
Later on, the beginning and place the results, starting from the file of the flash and see what comes out
After

Here I am with updates..
Today I have dug out to the network to find software suitable for the purpose of the topic started by munro, and I've done about twenty installations of software that, for the most part, they are recognised as less useless for the purpose.
At the end between the various tools, the better and functional, as well as winhex, which partially is what is searched, but is highly shit, is IDAPro, which I downloaded and fired.
The file of the flash has the offset that they will interact in the control unit and I show you some output:
seg000:001D60C0 dd 8000800h, 0E8038403h, 0D007DC05h, 0B80BC409h, 0A00FAC0Dh
seg000:001D60C0 dd 0F4010000h, 0DC05E803h, 0C409D007h, 0AC0DB80Bh, 20h dup(0)
seg000:001D6164 dd 8000800h, 84035203h, 0DC05E803h, 0C409D007h, 0AC0DB80Bh
seg000:001D6164 dd 0E803F401h, 0D007DC05h, 0B80BC409h, 0A00FAC0Dh, 20h dup(0)
seg000:001D6208 dd 8000800h, 84035203h, 0DC05E803h, 0C409D007h, 0AC0DB80Bh
This is very UNIX-like methodology of the processing of memories so now we have to run a few tests on other memories.
Please post an entire backup is not verginato and see if the extrapolation is outside any given sense.
Because of my ignorance I have to ask if you had the chance to post a backup of the body or to process the info only by the ecu and is only by the interpreter and "arm" of the functions of the ecu?
As a matter of curiosity, and if it were feasible we would change the ENTIRE screen of the dashboard, personalizing it (sorry for itself recently!)
I look forward to your feedback and backup to be put in the press!

The programming of the flash file is in Alllesmbly, with the files of the other memories we can understand the relationship, if any, of the functions and variables in order to define the functions that will be expressed with some variable but together we have it definitely..
From the guys posted something of any brand, as long as they are all memories

[tranky]

Alllesmbly = Assembly (typing error.. sorry)

A bordellone, but nothing impossible!

[munro]

mamma mia che casino....you understand something? what do you need the file of a microprocessor or all the backup ecu that the contents of the eprom,e2p, and micro?

[tranky]

That "casino" you see are only the functions that send him. In the main memory, there should be identifications of these codes.
Since here it is all in correlation, if you can send me a full backup of a any kind of control unit would be better, in such a way that:
I read in the central memory, and I see the ID and their identification on the main memory
I read the other memories and I see what you recall which functions in comparison of the memories.
After that we try to unravel the functions as they are defined and how they can change.. Then we'll need a guinea pig that loads the ecu!
I reveal the question of the body as soon as you have 2 minutes? I did not understand if it has a memory of whether or undertake functions related to the ecu but I think he has some of his memory from what I think... but I could be wrong.

[munro]

then guy can you please post the complete backup of an edc16c39 alfa 159 mjet 150cv so we stay in context for your ecu if you want I can also qualcosadi the most simple to start, because I believe that the edc16 is very complex to take apart...let's say that this operation that we want to try are excellent in the case of ecu dated, of which there are damos or you don't understand well the logic of operation...
for the instrument panel ..Tranky I could not tell you I'm in in principle of processing and repair motor on these subjects:body,abs,paintings, etc., I entrust myself to my partner electricians...
I can try to ask him on Monday so I do have to say, the operation, however, I believe that the dial functions in two ways that, alas, described you...i.e. it has both an internal memory is also receives instructions from the external view the tachometer or the signal on the odometer...

[tranky]

Thanks for the "guy" but so I have to be young.
Let's try this and if I can understand something we move on to one where you can load the EPROM to test it.
