ASSEMBLER\DISASSEMBLER

[rainstate]

was wondering what kind of assemblers\disassemblers you guys are using.I've i've tried the cats and the ida freeware but am having a hard time getting them to assemble.(tried getting it to assemble with tech edge but cant get it to work right.) thanks for your input

[RobertISaar]

the CATS disassembler is a joke.

IDA Pro is by far the best i've ever used.

i've never actually used an assembler though, i i punch out all of my code mods in machine code.

what BIN are you trying to deal with?

[rainstate]

It's a gm 6.5 TD. bin 16183977 . I have a XDF for it I found on line a few years back but I don't think its complete.I think that there is some extra I\O that I could utilize for some thing else.

$EC mask

[RobertISaar]

i'm certain i have an XDF for that, likely the same one you have, and IIRC, i thought it was rather bare as well, but i know nothing about the diesel masks.

if you upload the BIN you're planning on working with, i can at least get you started on a disassembly and should you happen to run across someone with a full version of IDA Pro(cough cough), i'll upload the IDB file as well.

[rainstate]

it's loaded

thanks

[RobertISaar]

it looks to be an $EC BIN, but are you certain the BIN pulled is good? i only used just the reset vector to start disassembling, and it's got all kinds of weird stuff going on, like trying to use some of the calibration as algorithm....

[rainstate]

yeah its a good one.pulled it straight from my truck.
I did a memory dump through the ALDL though,
That might be the problem.

[rainstate]

I burned my last couple of chips with this bin and it works with the XDF I have, but I cant remember if I checked the chips bin with the memory dump bin.I destroyed my burner when I moved a few months ago and need to replace it.

thanks for looking.I'll post a new bin when I get a new burner

[rainstate]

actually I have another $EC bin that I got from the moates site, dont know if it was read through a burner or memory dump, here it is.[attachment=0:29ljbwnb]BXYR EC.bin[/attachment:29ljbwnb]

[RobertISaar]

that one disassembles oddly as well...

[rainstate]

I should be able to have a new burner in a few weeks.( daughter needed a prom dress and everything that goes with it )

[rainstate]

Well I finally have found the time to use my new burner,had it for nearly a month, and you where right it does look funny.pulling it from the ALDL puts it in a different mode? Any how it comes out the same in the XDF though. If you where still interested in looking at it, it would be appreciated greatly.

I've used Donald Whisnant's code seeking disassembler for a bunch of GM work. I have Ida Pro and a few Moto specific disassemblers left over from a few years in school but the Moto specific tools run into problems with some of the addresses used by the GM processors.

My calibration ID software tags first.bin as being BPBN7103 which is from a 1994 6.5 turbo diesel with 4 speed auto trans. I also crossed the scan id (7125) from the uploaded cal against the scan ID for BJAX (6945) and they do not match. If you are truly using a 1994 calibration you might want to upgrade to a 1995 version. There were a lot of driveability bugs in the early cals.

[RobertISaar]

i found the PROM ID of the latest uploaded file to be correct... at least according to CalData.

$4000-4001: 1B 21 = 6945.


the only cals that use 6945 for their scan ID are BJAX and BPAL.
