Dumping the Serial Flash[edit]

The serial flash being used in the PS5 (at the time of writing) is a Winbond W25Q16JVNIM. It's about 2MB and is 150mil in size. Here's a pinout diagram of the flash.

In this guide, we will be using a Raspberry Pi to dump the flash (teensy boards may work too) Connect the pins to the GPIO header according to this table: (WARNING: LONGER CABLES MAY GIVE YOU AN UNRELIABLE READ)

Connections
Flash RPI
/CS GPIO 8
/MISO GPIO 9
/WP GND
GND GND
VCC 3v3
/HOLD none
SCLK GPIO 11
MOSI GPIO 10

Use this site to find the pinout for your Raspberry Pi: https://pinout.xyz/pinout/spi#

I will release my own tools later on, but I think flashrom works for now (haven't tried yet, see: https://github.com/flashrom/flashrom/pull/178)
