Hello there guys,
Im not so good with IDA and python and im a bit puzzled of how exactly i can run the scripts.
For example for the first one how can i define min and max ? Does IDA support any interactive way where you can type the variables ?
Kind regards.
copy script to a file in your disassembly directory as for example script.py then type: execfile("script.py") in the IDA python console afterwards type the functionname and arguments in the console, for example: processrom(0x80000, 0x80FFFF) |

Thanks for the replies guys  I will try those. I guess i can load them as snippets as well for faster access. |

Yes, of course you can. But the whole point of the tools is to avoid having to do it via UI because GUIs suck for handling large amounts of data that is best handled by automation.
Thanks Nyet, i was doing the address naming manually etc. What i was asking about "interactive" if you can use a command in the python script that actually popup a window in IDA to define e.g. min max or load a "file" For now i followed fluke9 guide and works marvelous.  |

sorry for threadjacking, dumping my hack also here: Rudimentary damos parer which will output a python script which can be executed in the ida console, this thing will label variables, also it will create enums for bitfields and apply them to the correct locations. Also names the variables with repeatable comments, your disassembly will then look something like this: 843214 loc_843214: ; CODE XREF: sub_842C26+46E↑j
843214 ; sub_842C26+47A↑j
843214 jnb word_FD7C.B_sa, loc_8432DC
843218 mov r4, ATM_bits
84321C and r4, #100h
843220 jmpa cc_NZ, loc_8432DC
843224 jnb word_FD20.B_atmtpk, loc_843270
843228 jnb word_FD7C.B_sa, loc_843270
84322C extp #206h, #1
843230 movbz r4, TATMSAE ; exotherme im Schub
843234 sub r4, #0Ah
843238 movbz r5, tikatm ; Abgastemperatur im Katalysator aus Modell
84323C cmp r4, #0
script here, which will generate namebytes.py : #!/usr/bin/python
import sys
if len(sys.argv) != 2:
print 'please specify filename'
exit
f = open(sys.argv[1], "r")
lines = f.readlines()
f.close()
#print 'loaded ' + sys.argv[1] + ' with ' + str(len(lines)) + ' lines'
print '# -*- coding: latin-1 -*-'
for line in lines:
data = line.split(',')
if len(data) > 1:
data[1] = data[1].strip()

print("add_enum_member(get_enum(\"" + enumname + "\"), \"" + varname + "\"," + maskstr + ", " + maskstr + ")")
run with: parsedamos.py file.dam > namebytes.py After generating the namebytes.py copy to your ida project dir and execute in the ida console with: execfile("namebytes.py") Hello I have a little question. everything works so far but the bit fields are not displayed to me. Enum screen all ok but in the IDA-View i don't see a name your example 843224 jnb word_FD20.B_atmtpk, loc_843270 843228 jnb word_FD7C.B_sa, loc_843270 me look jpg. |

Move to address 0xFD70 and press 'M' to assign an Enum entry. Select enum_FD70.

Ok thanks:-) yes but shouldn't the script do it itself? |

Maybe you think the script should give blowjobs too?  Improve it to do that if you want it to do it, and post here the result. |

Here a short script to copy or move bytes from one address to another.
Usage:
- Load script via Alt + F7
- Execute script by function call "moveCode(eas, eae, eat, erase)" in Python console
Function description:
- eas: Start address of code
- eae: End address of code
- eat: Target address where to put code
- erase: 0 = Keep source address space as it is, 1 = Overwrite source address space with "0xFF"
Hint:
- Make sure that target address space can be overwritten. Function does not check, whether there is already code existing, or not!

small script based on prj dam loader, but written to work with ida 7.5 fp = open(r"C:\Users\XXXXXXXXX\MY.dam", errors="ignore")
lines = fp.read().split("\n")
lines.pop(0)
print("Found: %d lines" % len(lines))
for line in lines:
if (len(line) > 0):
l = line.split(",")
if (len(l) > 4):
if (l[1].strip() == "/SRC"):
addr = l[-5].replace("$", "0x")
idc.set_name(int(addr, 0), l[2].strip(), 1)
elif (l[0].strip() == "/UMP"):
addr = l[-7].replace("$", "0x")
idc.set_name(int(addr, 0), l[2].strip(), 1) |

Maybe useful for those of you using Keil µVision, I wrote a script to import *.H86 HEX-Files to IDApro.
Usage:
- Go to "Hex View" or "IDA View"
- Click on the address where to put the content of your *.H86 file
- Load script via Alt + F7
- Confirm target address
- Select *.H86-file to import

i dont know where to put this and i didnt want to start a new thread only because of this so here it goes. Most of the time the a2l/damos is in german, and when you import it in winols it cumbersome to manualy translate it, so i wrote a simple python script that translates a csv defenition file (from winols export) based on another csv(this could be from a similiar ecu, etc) it needs some work but for the most part it works. Hope its usefull for someone. import csv
de = open(r"C:\Users\me\Desktop\f30.csv")
en = open(r"C:\Users\me\Desktop\f10.csv")
out = open(r"C:\Users\me\Desktop\outputmap.csv","w", newline="")
with de as file_de, en as file_en, out as outfile:
fieldnames = ['Name', 'IdName', 'AxisX.Name', 'AxisY.Name'] #, 'FolderName'
writer = csv.DictWriter(outfile, fieldnames=fieldnames, delimiter=";")
writer.writeheader()
german = list(csv.DictReader(file_de, delimiter=';'))
english = list(csv.DictReader(file_en, delimiter=';'))
cont1=0
print(len(english))
for row_de in german:
cont = 0
count2 = 0
for row_en in english:
if row_de['IdName'].lower() != row_en['IdName'].lower():
cont = cont + 1
if cont == len(english): #if after running throught english file no match found print german
writer.writerow({'Name': row_de['Name'], 'IdName' : row_de['IdName'], 'AxisX.Name' : row_de['AxisX.Name'], 'AxisY.Name' : row_de['AxisY.Name']}) # 'FolderName' : row_de['FolderName'],
#print(row_de['Name'] + ';' + row_de['IdName'] + ";" + row_de["FolderName"] + ";" + row_de["AxisX.Name"] + ";" + row_de["AxisY.Name"])
else:
count2 = count2+1
if count2 == 1: # in case there is more than one "idname" with the same name, this makes sure it only prints once per row of german
writer.writerow({'Name': row_en['Name'], 'IdName': row_de['IdName'], 'AxisX.Name': row_en['AxisX.Name'], 'AxisY.Name': row_en['AxisY.Name']}) # 'FolderName': row_de['FolderName'],
#print(row_en['Name'] + ';' + row_de['IdName'] + ";" + row_en["FolderName"] + ";" + row_en["AxisX.Name"] + ";" + row_en["AxisY.Name"])
cont1 = cont1 + 1
print("percentage = %.2f" % (cont1 / len(german) * 100), "%")
print("done")
also for the folder name( this one i have to work a bit more) import csv
de = open(r"C:\Users\me\Documents\Carros\ECU\mini\WinOLS rcz english.csv")
en = open(r"C:\Users\me\Documents\Carros\ECU\mini\WinOLS psa.csv")
out = open(r"C:\Users\me\Documents\Carros\ECU\mini\folder_translator.csv","w", newline="")
with de as file_de, en as file_en, out as outfile:
fieldnames = ['FolderName']
writer = csv.DictWriter(outfile, fieldnames=fieldnames, delimiter=";")
writer.writeheader()
german = list(csv.DictReader(file_de, delimiter=';'))
english = list(csv.DictReader(file_en, delimiter=';'))
cont1=0
for row_de in german:
cont = 0
count2 = 0
row_de1 = row_de['FolderName'].lower().split()
row_de2 = row_de1[0]
for row_en in english:
row_en1=row_en['FolderName'].lower().split()
row_en2=row_en1[0]
if row_de2 != row_en2:
cont = cont + 1
if cont == len(english): #if after running throught english file no match found print german
#print(row_de['FolderName'])
writer.writerow({'FolderName': row_de['FolderName']})
else:
count2 = count2+1
if count2 == 1: # in case there is more than one "idname" with the same name, this makes sure it only prints once per row of german
#print(row_en['FolderName'])
writer.writerow({'FolderName': row_en['FolderName']})
cont1 = cont1 + 1
print("percentage = %.2f" % (cont1 / len(german) * 100), "%")
print("done")
