Editing PSGroove

PSGroove is an open source program for executing the 'PSJailbreak' exploit, and injecting unsigned code into the lv2 gameos kernel during the PS3 boot process. 


== Supported Hardware ==

*AT90USB162 
*AT90USB646 
*AT90USB647 
*AT90USB1286 
*AT90USB1287 
*ATMEGA32U4 
... and maybe more 

== Compiling ==


Linux 
Prerequisites 
avr-gcc / avr-libc / git 
Under Gentoo: 

emerge -av portage-utils crossdev git
USE="-openmp" crossdev -t avr --without-headers
Under Ubuntu: 

sudo apt-get install gcc-avr avr-libc git-core
dfu-programmer (for installing) 
Download here: http://sourceforge.net/projects/dfu-programmer/files/ 

Older version available in the Ubuntu repository. 

sudo apt-get install dfu-programmerCloning the repository 
The repository uses the LUFA library as a submodule. To clone, use something like: 

git clone git://github.com/psgroove/psgroove.git
cd psgroove
git submodule init
git submodule update
Configuring 
Chip and board selection can usually be handled in the Makefile. In particular, update the MCU, BOARD, and F_CPU lines. Suggested values: 

Teensy 1.0: 

MCU = at90usb162 
BOARD = TEENSY 
F_CLOCK = 16000000 
Teensy++ 1.0: 

MCU = at90usb646 
BOARD = TEENSY 
F_CLOCK = 16000000 
Teensy 2.0: 

MCU = atmega32u4 
BOARD = TEENSY 
F_CLOCK = 16000000 
Teensy++ 2.0: 

MCU = at90usb1286 
BOARD = TEENSY 
F_CLOCK = 16000000 
AT90USBKEY / AT90USBKEY2: 

MCU = at90usb1287 
BOARD = USBKEY 
F_CLOCK = 8000000 
AVROpendous v1.1: 

MCU = at90usb162 
BOARD = USER (need to manually attribute LED pins in Board/LEDs.h) 
F_CLOCK = 8000000 
ATAVRXPLAIN: 

MCU = at90usb1287 
BOARD = XPLAIN 
F_CLOCK = 8000000 
Minimus AVR USB: 

MCU = at90usb162 
BOARD = USBKEY 
F_CLOCK = 16000000

Building 
On Linux, use the AVR GCC toolchain (Debian/Ubuntu package: gcc-avr). 

make clean
make
Programming 
Now program psgroove.hex into your board and you're ready to go. For the AT90USBKEY and other chips with a DFU bootloader preinstalled, you can get the dfu-programmer tool, put your board in programming mode, and run 

make dfu
For the Teensy boards, you probably have to use the [Teensy Loader](http://www.pjrc.com/teensy/loader.html) software. 

Windows 
Download and install WinAVR . 

Download and install msysgit


After installing msysgit, follow the Cloning the repository, Configuring and Building instructions listed for the Linux section.


Upload the hex to the appropriate device using the appropriate software.


OSX 
Once the prerequisites are installed, this is pretty much the same as the Linux process listed above.   

Prerequisites 
Install the following to get started : 

XCode - download from apple or install directly from an OSX DVD
MacPorts - BSD ports functionality on OSX
CrossPack AVR AVR toolchain for OSX


Open a new terminal window and enter the following: 

sudo port install git-core dfu-programmer
Everything else 
# get the source
git clone git://github.com/psgroove/psgroove.git
cd psgroove
git submodule init
git submodule update

# do the build
make clean
make


# put the board into programming mode
make dfu
Notes 
MacPorts includes a portfile for the AVR toolchain, however, the included version of avr-gcc(4.0.2) does not support the AT90USB1287, it may be suitable for other boards.   

Haven't tested the programming part yet, still waiting for a board to arrive. The programming command is likely to be "sudo make dfu". 

Using 
To use this exploit: 

Hard power cycle your PS3 (using the switch in back, or unplug it) 
Plug the dongle into your PS3. 
Press the PS3 power button, followed quickly by the eject button. 
After a few seconds, the first LED on your dongle should light up. After about 5 seconds, the second LED will light up (or the LED will just go off, if you only have one). This means the exploit worked! You can see the new "Install Package Files" menu option in the game menu. 




Board-specific notes 
Teensy boards only have one LED, so it will turn off when the exploit succeeds rather than turn green. Older Teensy 1.0 boards also have the polarity inverted. In general, a LED should do something when the board is powered, and do something different when the exploit works.
