Kiwidog has released the source for oni-framework, a tool described as a platform used to remotely debug/add functionality to embedded devices.
Even though the developer states that the platform is generic and can be used to help debugging various pieces of hardware, scene veteran Mathieulh has described Oni as “the open source PS4 debugger”.
