188w 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.
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
