Emulator and Decompiler
 

So I've seen someone had said he figured out a way to get the emulator working.

I was wondering if anyone else has been able to get this going? So far I've figured out what the emulator is, and how to decompile the navboot file, and tried to get the shell to run, but i can't seem to get it to work..

I'm posting this here, hoping that someone else wants to play with this, and share information.

os9exec - os9 Emulator Download

Is this to emulate the nav software on a PC? Been looking for this for a long time.

Tell me how you set it up and i;ll try it out.

Were you getting these errors?

So... what is the executable to run on the nav OS?

Hey Jochen: I see your back from holiday, i sent you some navcoder files the other day...

Anyway, that's about where I'm at....

Some things for people to look try:
- Open the files in the root of the Firmware upgrade CD in Notepad, Lots of junk in those files, but some useful info in plain text
- Decompile the navboot file.. go to a command prompt > and type decompile navboot (you might want to copy navboot and the decompiler to thier own directory)... once extracted you'll see lots of files, including one called shell... (which to me looks like the beginings of the os9 OS)

Does this mean that someone was able to create a software to run the nav os on a PC?
Is the nav os the navboot ??? :dunno:

:yikes:

Is this possible? I must try it!

myabe a little bit OT...did anybody succeeded in modifying romcol_1 in the navboot?

PS: I decompiled the navoboot...interesting but most of the stuff has not much meaning for me...:confused:

Yeap me too...

Hmm, Ok the decomplier works with the 3.38 version of the os9exec files.

"c:\decomplie navboot"

not found the emulator yet

There is very little information on getting the emulator to work, and even less info on getting the nav software to run..

But once decompiled, it looks to me, like that is indeed an OS inside the navboot file - just trying to figure out how to get it working is that part I was having issues with... Lots and lots of googling got me to this point so far.

If you do some searching you'll find that the os needs to be in the dd directory... but so far, ive yet to get it working...

Keep plugging along guys and post any developments you may have.

Link fixed

Ok try decompile some of the other files, in the same directory as the navboot file...
gsw_tools has some interesting looking test files....

Can I throw in a cheeky early request for automatic night mode when turning on the dash illumination? :D Does it come accross the K-Bus?

Info on OS9 emulator
 

From some searches

Yes many files in navboot

Hmmm, Sorry to resurect an old post, but...

I've just had a small step forward with this and managed to get hold of an os9000 microwave disc image that "boots" the os9app into an unix/linux type shell.

os9000 disc image, Here

Download and then unzip, then make a copy of the mw.dsk and rename it to dd (thats it just dd), have it in the same dir as the os9app.exe and then run os9app.exe (in a cmd window).

I've only had a small play with it but it could be a small step forward.

Commands found so far:-

Load, mdir, ls and init (to quit).

Dir.

I don't know what this all means, but it sounds promising. :)

Well hopefully it means that we can "load" the decompiled nav modules into the emulator shell and mod stuff.

It looks like the disc image is missing a few tools ("ls dd", is empty), so it a baby step.

"That's one small step for a man, a giant leap for mankind" :thumbup:

:thumbup:

Great news!

Reverse engineering the OS / setup would lead to a new chapter of DIY regarding the navigation system.

Some work some don't.

a serious problem might be that os9exec emulates motorola68k CPU, thus run os9/m68k programs while the mk2-mk4 series based on MIPS platform... I think mk1 is based on m68k though

Did a google search relating to the CPU. Found this instead. It almost looks like its plug n play. It must talk to the IBUS.

Anyone buy one of these yet? Dynavin E46 Radio

I understand that this will not replace the NAV in the E83 and is specifically for the E46 and not everyone that has an E83 also has an E46.

dynavin

This is a custom E46 style GPS HU. Looked over threads from V1 to current V5. Sounds impressive. Looks plug n play. With this in place would most likely take the CarPC out.

What news about emulating OS9?

None mate, its stalled :(

OK, I will try do some experiments, if any luck I will post :)

If you need any of the tools I have then I'm happy to send you them mate.

Well I would need OS9 decompiler, because I couldn't find it anywhere

you have PM

Bu using NavTweak I can extract files from navboot.
It that the same as Decompiler?

I tried to run os9exec version 338 for Windows (os9exec_338_Windows) with files I extracted but no success. Maybe I am doing something wrong?

Here is what I did
1. in Window 7, start CMD with admin right
2. in cmd got to directory with os9exec and bin directory.
3. extract file from navboot to the same folder as os9exec using NavTweak
4. in cmd type os9app.exe kernel

no matter which program I extracted from navboot, it returns the same thing

ccfj1:
Can I have a copy of decompiler too?
Can you show me how you got Emulator work also

Many thanks

Yes, in effect it is.

Have you loaded the os9 disc image mate?? (you need a os9 disc image called DD in the same dir as the os9app.exe file).

That wont work, as there is no link between the disc image and the "real world" dir (that the kernel file sits in).

This is essentially the problem, I can decompile the navboot, but I cant get them into the OS9 environment (to be able to run the config_tool).

I do.

You pretty much have it mate, you just need the DD disc image and the decompiler. PM you real email and I'll sent them to you.

Hi guys,

I registered here specially to resurrect this topic. Was there any progress?

Found may be interesting info:
Wiki :: en_OS9_x86_Install

Did anyone know about QEMU? It supports MIPS as well, so it might be possible to create virtualbox for navboot, I hope...

Don't have much time at the moment, so would be grateful if you share what have you found by now...

Very interesting, I've downloaded and tried it.

However, I cant get the network part to install as the installer says "invalid use of install", I may require installing on a native XP machine.

As for updates, None... if this provides a way of allowing the navboot (or files therein) to be "loaded" into the os9 install AND the config_tool runs then that would be a huge step forward.

Good find though :)

Sorry for rare posting,
unfortunately I also could not get network part working, seems the TAP driver does not fit Win7, and then one installed from latest version of OpenVPN does not fit current OS image...

Just to share another finding:
OS-9 LV II and OS-9000 x86 images

There is a link (still working) to the Microware evaluation CD, (only for x86 tough) with Hawk development environment, unfortunately not checked yet and no idea, whether it might be useful somehow or not...

Finally got working the network part with the emulator above on Win7.
Simply download latest OpenVPN package, unpack end extract x64 tap driver. Then go to Device Manager->Action->Add Legacy Hardware, then point to the .inf file of the driver extracted. Et voila! Now I can connect from host to emulated OS as in doc above.
Note: if the driver from previous install approaches is present in Device Manager (typically as "unknown device"), it needs to be removed manually, "update driver" does not work.

The .bat file included to .zip package needs to be adapted for a new driver path and also "run as Administrator".

Also works fine with latest QEMU binaries for Win that could be found here: Qemu On Windows

Hey zyz, good work,

I cant seem to find the x64 tap driver though, all the files I can find are .exe or msi, so I cant extract them, do you have a location for the driver part only?

Scratch that I now have a login on 10.0.2.14!!!

now to try and upload and use the configtool

OK, uploaded the config_toolm, but I can run it or even get into the dir thats holding the files!!!

anyone have any syntax options for things like dir/ls or run etc???

Sorry I didn't get what are you trying to do.
Walked through the directories, it seems like the image was built based on eval CD I provided link to.
Now I guess we have to think the way of building an image for MIPS VM...

Hi,

I am working on hacking of E65 MOST bus with implementation of Raspberry Pi.

Project page
https://www.youtube.com/watch?v=Lf_BmMbcn3E

It would be helpfully to me to disassembly navigation firmware source codes. To get detailed information about MOST commands.

Would you mind sending decompiler to me? Megaupload no longer exists and I can't find decompiler on internet.

Thank you very much.
