213w ago - After the release of the hack for Xenon, Falcon/Opus and Zephyr XBox 360 motherboards, today we get the Free60 JTAG / SMC XeLL Hack for Jasper (v4) motherboards with 16MB NAND chips (so NOT compatible with 256 & 512MB NAND yet).
This NAND image will boot your Jasper XBox 360 right into XeLL, which allows you to launch linux distros or run libxenon homebrew software, as long as you never upgraded it via the normal MS upgrade procedures to kernel 849x or higher.
To quote from the NFO File: Finally the Jasper JTAG Hack is here
This is XELL (compiled 11.09.09) inserted into 6712 Jasper-Kernel.
Don't wonder about the Filesize, its correct like that. It just flashes the beginning of the NAND so your console specific data like MAC adress will stay.
To quote: A 'rebooter', allows to 'reboot' the 360 into an MS kernel after starting it with the JTAG Hack... in this case (freeBOOT v0.01) it should reboot the console into MS kernel 8498 (but I assume 8507 will be possible too, and it's probably also the first step into rebooting into patched/modified MS kernels).
The readme says it requires the Cygnos360 v2 chip atm, I'm assuming they need it to automatically reset the SMC back to original.
Booting your 360 into 849x+ and keeping the JTAG Hack working was impossible until now, because updating to 849x+ via the MS update procedures burned a CB-fuse which made it impossible to still perform the JTAG Hack.
If you already updated your console to 849x+ via normal update methods there is still no solution for you, but if you have a JTAG 'hackable' console (kernel 7371 or lower on NAND) freeBOOT should allow you to 're boot' it into 8498 via the JTAG Hack.
217w 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...
