JAISPI - Raspberry Pi SPI flasher for PS4
JAISPI - Utility to read and write to the main memory (MX25L25635FMI-10G) of PS4 with the Raspberry Pi through the SPI protocol.
- Support MX25L25635FMI-10G
- Full Erase
- 1x Raspberry Pi (see here for where to buy)
- 1x SD Memory (for Raspbian, a 4GB minimal is recommended)
- 1x PS4 Serial Flash MX25L25635FMI-10G desoldered from console
- Raspbian (http://downloads.raspberrypi.org/raspbian_latest)
- Win32 Disk Imager (http://sourceforge.net/projects/win32diskimager/files/latest/download)
- Putty (http://the.earth.li/~sgtatham/putty/latest/x86/putty.exe)
|8-Pin||16-pin||Usage|| Raspberry Pi
|-||1||SIO3||NC||8pin: Not Available - not used / 16pin: Serial Data Input & Output (for 4xI/O read mode)|
|8||2||VCC||17||+3V DC Power Supply|
|7||3||HOLD#/RESET#||NC||8pin: Hold, to pause the device without deselecting the device / 16pin: Hardware Reset Pin Active low|
|2||8||SO/SIO1||21||Serial Data Output (for 1 x I/O) or Serial Data Input & Output (for 2x I/O or 4x I/O read mode)|
|3||9||WP#/SIO2||25||Write Protection: connect to GND or Serial Data Input & Output (for 4x I/O read mode)|
|5||15||SI/SIO0||19||Serial Data Input (for 1 x I/O) or Serial Data Input & Output (for 2x I/O or 4x I/O read mode)|
Use short wires, esp. if you are not adding the 0.1µF capacitor between ground and vcc as close as possible to the chip
newer Raspberry Pi model B+ and Raspberry Pi model A+ both use same pinout for the first 26 pinheaders as the previous nonplus model, so it should work on that as well.
- In "Image file" select the downloaded and decompressed Raspbian image (2013-09-25-wheezy-raspbian.img at the time of this writing)
- In "Device" select the drive where the SD memory is.
- Select "Write".
After finished writing, put the SD card in the Raspberry Pi and power it up by inserting the USB cable.
Remote Shell into Raspbian
- In Host Name put: raspberrypi
If this doesn't works properly, go to the router, find the IP assigned to your Raspberry Pi and use that instead,
- Select SSH (or Raspberry and Putty support TTL https://learn.adafruit.com/adafruits-raspberry-pi-lesson-5-using-a-console-cable/overview)
- Select Open
It will request a Login. According Raspbian the user is "pi" and the password "raspberry" (Both without quotes).
Insert the following commands:
sudo -s cd /bin wget http://jaicrab.org/Ps4/Tools/JAISPI/jaispi chmod +x jaispi echo "#blacklist spi-bcm2708" > /etc/modprobe.d/raspi-blacklist.conf echo "blacklist i2c-bcm2708" >> /etc/modprobe.d/raspi-blacklist.conf reboot
Installation is complete. By Putty you can access the Raspberry Pi. To run the command jaispi you need to be root (sudo-s):
-i /dev/spidevX.X Get ID from flash -r file.bin /dev/spidevX.X Read entire flash to file -e /dev/spidevX.X Erase entire flash -p file.bin /dev/spidevX.X Only write blocks differences from file -v file.bin /dev/spidevX.X Verify blocks with file
-i: Displays information of the flash.
