JTag Port on PS3 Blu-ray Drive Board Located and Mapped


Sponsored Links
250w ago - Developers at DemonHades have located and mapped the JTag Port on a PS3 Blu-ray drive board today.

To quote, roughly translated: I found the JTag port for the Blu-ray Reader on the PlayStation 3. Last night after finishing the research meeting I went looking for information about BD integrated reader.

In and looking at the information that I found on the back of the plate reader I saw that there is no connector terminals, these terminals belong to a connector which connects 'something' via terminals and through the Internet I found the points used in a JTag, including the TDO, TDI, TMS etc.

Originally developed for printed circuit boards, it is currently used for test of submodules of integrated circuits, and is also useful as a mechanism for debugging embedded applications, as it provides a backdoor to within the system.

When used as a debugging tool, an in-circuit emulator that uses JTag as the transport mechanism allows the programmer to access the debugging module that is integrated into the CPU. The debug module enables the programmer to correct their errors and code logic of their systems.

There are consumer products that have a JTag port integrated, so that the connections are often available on the PCB as part of the prototype phase of the product. These connections can provide a simple way to reverse-engineer.

As you can see we have a door strike to try to get the firmware, decrypted data, and all that is able to control the Blu-ray reader.

The data from this integrated JTag will CXD5063GG-1. CXD5063GG-1 = ASIC / CPU - Video Decryption Device Sony Computer Entertainment Inc., CXD5063GG-1, 2005 SCEI, 120,748 0608HAL.

Ok I feel the need that I need to mention something quite important.

Nothing was "discovered", those pinout's were taken DIRECTLY (its a print screen from the docs!) from one of the Sony PS3 Service Manual's - Yes, the service manual identifies the JTAG for the BD Drive, as well as for the CELL, SYSCON, etc - quite useful if these items were not disabled at the factory.

Now a days - these things are blown at production, companies have learned that leaving JTAG's active can be a very, very, very, bad thing.

Its very old news - we tested these exact points (and others) nearly a year ago and got nowhere- they are blown!

Now, maybe if you had say, a PS3 TOOL, or a nice PROTOTYPE with active lines it would be something different
Why didnt you share this in the past cjpc now demonhades is taking the credit and telling everyone he has been hardworking on those pinouts and that everything shown is his work.

And the front page news quotes "his work" instead of yours, I know maybe you dont like the spotlight and that this is a deadend, but why would we have this news and credit that to his site, because now all the net is looking at him. He may be a fake but he is getting all the attention he wants.

Just a thought and thanks for the information you are sharing with us now, if disabled (the jtag port) we are pretty much screwed.

The best I can do is below.
Thanks Im pretty good with the soldering iron, and just wanted to know if we ever need to access the jtag port how hard it will be to solder, and its doable with small wires and a multimeter it can be done and the proper soldering iron.

That will be a tough one to solder, could you post a close up of the connector area to see the solder points. Thanks!

Imagine using your own custom GUI or running an emulator straight from the xmb. Imagine what sort of things could be done with the RSX (decoding, encrypting, encoding, HD video playback, a competent Linux environment). The possibilities reach far beyond merely playing pirated games (which is pretty impractical considering the amount of data that a blu-ray disc can potentially contain). This is an exciting step towards achieving such possibilities and I am very eager to see what sort of advancements this discovery will bring.
Most games are gonna be bought this gen anyways due to the single player campaigns being usually gimped for multiplayer content, and when you take into account that playing burned games online puts you at risk of being banned.

I dont see too many benefits for playing burned games this gen.... well cept maybe on the Wii...
