Dumping the Serial Flash[edit | edit source]
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)
| Flash | RPI |
| /CS | GPIO 8 |
| /MISO | GPIO 9 |
| /WP | GND |
| GND | GND |
| VCC | 3v3 |
| /HOLD | 3v3 via 10k |
| 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)
See this page for more info about the flash: https://www.digikey.com/htmldatasheets/production/3221237/0/0/1/W25Q16JV.pdf
