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


Sponsored Links
254w 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.

Heh, dunno if something got mupped from in translation...
Yep, somethings did, but the whole idea is still there.

I don't know if it's just too late, but some other translation would be like this:

Hello boys, thanks for the video chakkal,

Last night I talked to CJPC, a friend of mine, and the PS3News site admin and besides they helped me, he said that he will also test the port. I have also received PMs from people who wants to collaborate with this investigation by bringing important devices such logical-digital analyzers and high precision oscilloscopes.

So, if CJPC told me that will also test the port … I highly doubt he even knew about it from before, furthermore the only evidence I have, about the “information” exposed on the internet, refers to the port or bus that connects the BDDrive to the PCB, which also has 2 TX and RX points.

In fact, I have an image of how looks the JIG used in the Sony Costumer Service, in which they use the connector from de bus to run some tests, and even when we’re talking about 2 different kinds of ports … well I think it’s interesting to know.

Best regards and thanks

Well, my spanish language skills are non-existent...

Don't worry, the guy who originally wrote the message isn't quite articulate .... it was hard to read even in spanish

Hello guys, thanks for the video chakkal.

Last night i talked with CJPC, besides helping me he told me that he will test the JTAG port, i have received 1 private (message forum? i guess) of a lot of people who wants to help me with osciloscopes wih great precision to colaborate with this project.

So, CJPC told he will test the port too.. i highly doubt they knew it before (the port)... the only thing that is exposed in internet talks about the port or ((1))bus that conect the BD Drive with the PCB, wich also have TX and RX points.

Besides, I have a picture of the JIG used in S0ny's Repairing Station (they called SAT wich is the place who receives the PS3's in warranty) and they use the conector of the bus named early((1)) to do some test, even if we are talking about two diferent ports it interesting to know something about it.

Sorry if i have some mistakes.

Heh, dunno if something got mupped from in translation, but needless to say, things did not go down like that- I said that he should test the port if he wanted to, and try using a scope to examine the data coming off it - if any.

Like I said in my previous post, we tried the JTAG(s) nearly a year ago - with no success!

Maybe it's not useless... Maybe someone decides to probe his/her PS3 and finds a way to re enable them (hardware-wise) or find another way to access the BluRay reader. It's a start, at best.

Ok,, there still seems to be some confusion...

What demonhades is saying is that the connector that connects the drive to the ps3's mobo has already been documented (the pinout's)

And that this one is "new" i.e. new to the internet.... though the fact remains the same that this has long been known even though not disclosed to the general public..

Man i really hope that this could lead to something good like what we have for the Wii and the Xbox 360. This sounds promising. I was wondering when some one would figure this out!!! If we could find a usefull hack i def. get a bluray burner i mean the blank disc are def cheaper then cheaper then having to buy every game.
