Today we received word from mariayo2 that Spanish PlayStation 4 developer JaiCraB has continued his previous PS4 development releasing a JaiSpiMod.hex for Teensy++ 2.0 with details below.

Download: JaiSpiMod.hex / JaiSPImodv0.5.hex

To quote, roughly translated:

JaiSpiMod converts MX25L25635FMI-10G flash memory in a usb mass storage.

This allows a more direct and rapid manipulation than other solutions. You do not need drivers for the system.

It requires:
  • Teensy 2 ++ (pjrc.com/store/teensypp.html)
  • 3.3 Volt Regulator for Teensy (pjrc.com/store/mcp1825.html)
  • Application Loader Tennsy (pjrc.com/teensy/loader.html)
  • JaiSpiMod for Teensy2 ++ (linked above)
Scheme:
Code:
Teensy2 ++      MX25L25635FMI-10G
---------       -----------------
+ 5V            Pin 2
B3              Pin 8
B2              Pin 15
B1              Pin 16
B0              Pin 7
GND             Pin 9
GND             Pin 10
There is an optional pin enabled to display information about the job.
Code:
D3 -> Serial COM Debugger
Installation:
  • Weld the plate 3v3 regulator.
  • Run Teensy Loader Application. Load JaiSpiMod and program.
Operation: (via http://jaicrab.org/?&a=Ps4/Article/JaiSpiMod)

Attention! Connecting JaiSpiMod Windows may give the option to format the drive. Not unless you are filming who want to have a nice PenDrive 32MB.

If Teensy2 ++ plate light flashes every second means that there has detected MX25L25635FMI-10G flash memory. In this case check connections. Debugger you have the option to check the status.

Connecting JaiSpiMod us create unformatted USB external drive (if not formatted).

The advantage of working as a USB mass is the convenience of direct access to a specific sector of memory. Direct manipulation on sectors. I personally work directly on sectors with WinHex.

:arrow: Update: Teensy2 -> JaiSPImod (UPDATE) Support for EN25Q64, MX25L1006E, W25Q64BV and Enabled PS4 CHECK (via http://jaicrab.org/?&a=Teensy2/Tools/JaiSpiMod)
