Inspired from prj, i made this for MED9 Ecu's. Its not finished yet because i have a few things to fix, but here you are. It also have the ability to load RAM-Values from an A2L file into it (you need to convert the file first, for instructions see the video) Video: https://youtu.be/_XxJVAzGEFs |

I have a question(please forgive me for my ignorance). I have a a 8E1910115G ecu, I don't have the specific A2L for it just one for a 2005 2.0t FSI Audi A4 B7. Can I load RAM-Values from that A2L? |

Hy, basically - no. An A2l MUST match 100%, there are very rare cases where an A2L from a different ecu/sw matches 100% |

Thank you. I used it last night on the Audi 2.0 tfsi A4 bin and A2l floating around here. I was unable to get the A2L portion to work correctly. Ill attach them tonight for you to see. The first part of it worked well though.

Most of the people here whatever they shared didn`t require an online converter for that.... |

Hi I did do one of these last year and its floating about on the forum somewhere, I'm guessing they will be very similar however mine didn't have the A2l capability so you win...Haha.. I'll give it ago as the A2l function is good IMHO |

BTW, I discontinued the script because it is possible to make this much better with direct IDA commands. I can post my me7.py file if you like - maybe you can get some more inspiration  |

Here are the relevant functions for basic ME7: import idc
import idaapi
def processrom(min, max):
if min > 0:
min = min - 1
curaddr = idc.FindUnexplored(min, idc.SEARCH_DOWN)
while curaddr < max:
if idc.MakeFunction(curaddr) != True:
idc.MakeCode(curaddr)
curaddr = idc.FindUnexplored(curaddr, idc.SEARCH_DOWN)
return
def makesegments():
idc.AddSeg(0xE000, 0x10000, 0, 0, 0, idc.scPub)
idc.RenameSeg(0xE000, "IRAM")
idc.AddSeg(0x380000, 0x390000, 0, 0, 0, idc.scPub)
idc.RenameSeg(0x380000, "XRAM")
return
def setdpp():
idc.SetSegDefReg(0x0000, "dpp0", 0x204)
idc.SetSegDefReg(0x0000, "dpp1", 0x205)
idc.SetSegDefReg(0x0000, "dpp2", 0xE0)
idc.SetSegDefReg(0x0000, "dpp3", 0x03)
idc.SetSegDefReg(0x800000, "dpp0", 0x204)
idc.SetSegDefReg(0x800000, "dpp1", 0x205)
idc.SetSegDefReg(0x800000, "dpp2", 0xE0)
idc.SetSegDefReg(0x800000, "dpp3", 0x03)
return |

Rly? I searched a time for a solution for MED9 and dont find something, and it was boring, adding it manually each file i want to open so i made this. However, thanks for the appreciation  Doesn't seem to work with IDA 6.5
I'm working with version 6.8 so i made it for this version. Maybe someone can change the script for older IDA versions. Here are the relevant functions for basic ME7:
Thank you! I will take a look onto it. Is there a way to inject the python scripts and adding buttons for each function somewhere on IDA or in an external window? I never worked with the python integration, except the console at bottom. |
