Making Isolated SPU Modules and Loaders

Introduction

  • E.g. to dump your ATA, ENCDEC or EID2 keys you have to make signed isolated SPU modules or loaders.
  • This is a tutorial how to do it on Linux (it doesn't matter on PC or PS3).

Tools

SPU GCC Compiler

  • You need SPU GCC compiler to compile your code and create binary version of it.
  • On PS3 Debian, just install spu toolchain.
  • You can also cross-compile SPU GCC toolchain for your Linux PC.

ps3tools

  • You need these tools to decrypt PS3 isolated SPU modules and loaders.
  • You also need it to sign and encrypt your own SPU modules and loaders.
  • self_rebuilder doesn't work properly with isolated SPU modules or loaders. Therefore, i made a new tool which works with isolated SPU modules and loaders. It's called iso_rebuilder.
  • See my GIT repop: http://gitorious.ps3dev.net/ps3otheros/ps3tools


How To Test Isolated SPU Modules and Loaders

  • I test my isolated SPU modules and loaders with PS3 Linux and spuisofs/spuldrfs Virtual File Systems.

spuisofs

spuldrfs

Example: Making dump_ata_keys.self

  • First you need sb_iso_spu_module.self from your NOR/NAND flash or from PS3 update file.
unself sb_iso_spu_module.self sb_iso_spu_module.elf

Example: Making dump_encdec_keys.self
