The Infotainment Project

MOD EDIT 8/12/15:

INDEX FOR THE INFOTAINMENT PROECT can be found here:

http://mazda3revolution.com/forums/2...t-project.html

ONLY USE IT AS A REFERENCE. ALL QUESTIONS AND COMMENTS REGARDING THE INFOTAINMENT PROJECT SHOULD BE POSTED HERE.

----------------------------------------

So, the Infotainment system is great, but it has me thinking how much greater it could be. There's so much potential wasted right now, and I would like to untap some of that.

The original post: http://mazda3revolution.com/forums/2...omponents.html.
This got me thinking. This is obviously a linux-based OS running on an ARM chip. This was seen on this post as well: http://mazda3revolution.com/forums/2...tics-menu.html

I'm a software engineer, but don't have any experience dealing with low-level linux based systems. I would love to be able to either install custom, modified linux operating systems in the car or just be able to alter parts of the system to enable hidden or disabled parts of the system.

For instance, every european market has the ability to buy connected services (live traffic, weather, etc), and the Japanese market even can play DVD's and watch live TV!

This may at least give us the ability to upgrade our own systems without visiting the dealer, or use other applications through our phones such as Waze.

What I think may help here is getting the update code dump. This would be solved easiest if someone knows a dealer that can get the update software on a USB stick. If someone could upload that somewhere, we could then start analyzing the update procedure and the software and hopefully fine some way to hijack onto that process.

This is perfect. I was about to start a thread asking where/how I would begin installing after market stereo to replace the infotainment (because I want CarPlay THAT bad), but I know its damn near impossible.

I'm a System Administrator, but not smart enough to edit something even as simple as low-level linux code, but I'd like to contribute or help in any way for those that are!

Subscribed ! Wanting to find out more too.

Dumb question... but anyone wanna try plugging a USB keyboard and see if any Linux shortcut keys would bring out the system console/kernel/terminal ?

Not sure how sensitive those Linux OS would pick up PnP keyboards

I tried, didn't seem to be recognized by the kernel. Which shortcut keys did you wanted to try?

Try these combos Ctrl+Alt+F1 , F2, F3, F4, F5, F6 and if any of these work than you should see a "comand promt" and than you can press Clrl+Alt+F7 than you should be back at youre user interface if this had no effect for the lulz of it try to press Alt+Ctl+Delete and see if it reboots than we know that the keybord is recognized

Through the software components post, there are people that have figured out that, via wifi, openssh is available. The problem is that nobody knows the root password. There is one person that did try to brute-force it with a dictionary attack, but after 10k tries or so gave up.

Maybe that may be a way to go about this too? That is, if someone has connections to find out that password or knows flaws in openssh to force a way in?

From what i can dig up about i without having the car in my hands i can see that it runs with a Freescale i.MX 6Q Processor an a Linux 3.0.35 Kernel.

If someone wants to try to ssh to the car, Useing the user "root" and som combos of the 4-8 last digits of there VIN#(That wil make the pwd a "unique" for that car and "known").
If there is no sucsess with that than try different usernames as fx. Mazda, mazda, M3, m3, Japan, japan and so on.

I can't wait to get a hold on my M3 when it arrives in Aug.

But I'm not willing to tear into the system, when dealers have the binary. I've patched binaries before, but only Intel op codes.

Try all lucky guesses you want, afraid it is not that simple: my SSH string has no obvious relation with my VIN.
