Developer 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”.
However, a quick look at the source code shows that no PS4 functionality is directly included in the framework’s repository for now, except maybe for a reference to ONI_PLATFORM_AARCH64_BSD as the first supported platform in the framework’s config.h file.
Porting the tool to a new platform is clearly explained in the tool’s readme, but involves deep knowledge of the target system.
If people want to give a try at porting it to the PS4, the source can be found in the link below. Otherwise, fingers crossed that Kiwidog will share his actual config files for the PS4. I fondly remember the good days of the PSP and its awesome debugger, psplink. Having such a tool for the PS4 would be awesome.
Someone will have to do the work to port it to any platform, it by itself doesn’t provide any specific platform abilities. Which a few people have been doing in the case of PS4, but it’s not the original use case.
My understanding here is that although Kiwidog himself does not necessarily have the PS4 config files, other hackers might, and might be willing to share them.
Download Oni Framework
You can Download Oni Framework on the tool’s github here. You’ll have to build from source.
