Video: PS Vita Crash CMA Debug Time via Xcode Execution Demo


111w ago - Following up on my previous post, below is a video demonstration for those interested dubbed PS Vita Crash CMA Debug Time via Xcode Execution.

I just released a fast small video to show the crash and freeze of the PlayStation Vita system using Xcode Execution. I also explain how to check every information coming from the CMA to PS Vita (debugger).

Below is a pastebin with tutorial and the video that show you something interesting.. As I promise and I do what I said

The tutorial to Debug CMA PS Vita Under MacOS and Xcode: http://pastebin.com/40FrAJXg

CMA Debugging PS Vita Under Xcode Execution Tutorial

You need a Dev account Apple to have Xcode that you can use your MacOSX under a Development Environment

1- Launch Xcode (Spotlight -> Xcode)
2- Create a Empty Project (MacOSX)
3- Enter whatever name on the Product Name (For Example PSV)
4- A new window appear, change command-line builds use Debug than release
5- Click on BreakPoints
6- On the top menu of the Xcode, choose Product and make a new scheme and name your new scheme psv for example, press ok
7- A new windows appear that you can edit your scheme on the left menu you can see RUN click on it and edit the run configutation build configuration -> Debug Executable (you need to choose the CMA.APP) for that, just click on None to Other and here you choose the CMA.APP Debugger, you can choose ever LLDB or GDB (choose by default GDB) Launch = Auto
8- Choose Diagnostics and here active every option Memory Management (malloc, Guard Malloc, Objective-C) Logging (Memory/execptions/Dyld) Debugger (Legacy->Stop on debugger and debugstr) Click OK (don't forget to active breakpoints before click Ok) click OK
9- Plug-in your PS Vita and Click on RUN (if you are connected in Wifi you just connect fast and disconnect)

Xcode/IO Framework, etc it's the best way to exploit the PS Vita under MacOSX and as you would see, the Sony have a strong access to your kernel system that i really don't appreciate and can control everything

The PS Vita use also NFS -> Network File System and Open Remote System File that ping pong between the PS Vita and Sony Server.

Hope that would help some smart dev And here the video that show you a example of what you can do





Some PS Vita user ask me the PS Vita Windows Driver that i made it's available on the older thread PS Vita 1.50 Firmware but I reuploaded the driver that you don't need to search

Download: PS Vita Driver (Nabnab)

Griever2Kx It's hope to you, if you want to use your PS Vita use it and update don't worry about the update right now, anyway FW 1.06 is a firmware with too much bug that give you some problem it's unstable and some app/game will not run correctly with this Firmware. It's more easy with 1.06 but also more unstable.

I see you doing well in ''open'' the Vita i'm still read the hints you left and try to learn more about ARM.

Can you please answer my question!!! FW 1.06... should i stay at 1.06 because its much easier to enter the Debug-Mode ?

Thank you.

Hi Nabnab,

I'm sorry if you feel attacked and/or insulted I wasn't trying to be disrespectful. It was just my dev' curiosity who need to be feed.

All your previous pastebin was information dispatched and not always easy to gather them together. For your point of you, it's easy because you have everything in you hands, but I think that you can understand that from the point of view of another person some clarifications are necessary to understand exactly what you are achieving and how we can reproduce what you have done.

By the way, I'm under Mac OS and interested to know how to debug CMA on MacOS.

Hi everybody,

Some great news on my work PS Vita.

1- I can crash easily the system with the USB and dev execution (my CMA PS Vita crash badly and freeze the system)
2- I found a easy wait to read/write on the PS Vita system
3- CMA = Pretty Pretty Bad Spyware that control all your action, better to make a alternative

Also i don't put all my dev load on the pastbin, so heavy stuff but check the partial (that can help other dev) unfortunately i can't help for now on Windows because i'm working only on Mac OS, the dev that want to know how to debug CMA on MacOS, please let me know

Thank you, this will be useful to understand exactly how you achieved that and what is the next step to have native homebrews and not PSP homebrews.

And if you have time, I'm still willing to speak with you by live messenger, irc, skype...
