gdbsrv

This is a simple GDB server that can be executed on a Playstation 4 or Playstation 5 that has been jailbroken and is running an ELF loader. The server accepts connections on port 2159, and has been tested with gdb-15.

Building for the PS4

Assuming you have the ps4-payload-sdk installed on a POSIX machine, the GDB server can be compiled using the following two commands:

john@localhost:gdbsrv$ export PS4_PAYLOAD_SDK=/opt/ps4-payload-sdk
john@localhost:gdbsrv$ make -f Makefile.ps4

Building for the PS5

Assuming you have the ps5-payload-sdk installed on a POSIX machine, the GDB server can be compiled using the following two commands:

john@localhost:gdbsrv$ export PS5_PAYLOAD_SDK=/opt/ps5-payload-sdk
john@localhost:gdbsrv$ make -f Makefile.ps5

Building for GNU/Linux systems

Assuming you have a compiler toolchain installed on your GNU/Linux system, the GDB server can be compiled using the following command:

john@localhost:gdbsrv$ make -f Makefile.posix

Known issues

• Symbols from dynamic sony libraries are not loaded correctly at the moment.
• A couble of arguments passed to the ELF are allocated on the heap, so gdb may report errors when trying to resolve the arguments to _start()
