Ktag, and Jtag

[bart]

I would like to ask a question, even if probably for many the answer ? granted...
What? the difference between the Ktag and the Jtag? :confused:
Thank you in advance for the answers you receive? :)

[bart]

I don't know to interpret the lack of answers why? too obvious demand, or the opposite...

[chicco]

The ktag should be a tool to trade on the ecu, the jtag instead of a protocol or system programming for microprocessors, I think that is so? otherwise, someone correct me.

[giarras]

the exact grain:

JTAG stands for Joint Test Action Group ? a consortium of 200 companies producing integrated circuits and printed circuit boards for the purpose of defining a standard protocol for the functional testing of such devices, which tend to be more and more? complex and difficult to control, up to make impractical the traditional manual methods or automatic (and to increase in a non-competitive Time-to-market”). Aware of these needs, the large industries have chosen a road that, by sacrificing a small part of the available resources in the integrated circuit, allows for testing the rational of the board on which it is installed. In addition to this there ? the possibility? have a functionality? additional (turning the control from the feet towards the inside of the component), such as easy programming of memories, micro-controllers, and other programmable devices) with a single operation, the possibility? debugging of the firmware and the possibility? to activate the automatic test (called BIST Built-in self-test) that is inserted permanently in the electronic components to check their functionality? (total or partial).

ktag only a tool.

that car use jtag?

that car use jtag?

Hello
Cuasi all the ecu (denso, hitachi, etc) car japanese 2004-2005 forward using Jtag with micro Renesas.
But now many car made in europe, using Jtag micro Nexus.

KTAG ? a tool JTAG ? a mode? of work (just like BDM BOOT MODE)

the KTAG ? a tool Alientech and this name was born from the fusion of two names : K is for Kess (I think the best existing tool for chiptuning for cost-development-work procedures)TAG that is derived from the way of the work of all the ecus that support the JTAG processors Renesas, Nexus, Mpc5556 (marelli 8JF, or 8DF, for example). KTAG ? designed to work with 3 mode? : BDM, BOOT ST + TRICORE and JTAG

[bart]

With a little delay, but thanks 1000 to all for the explanations received. Now ? much more? clear :)
A doubt that I ? built reading the answers, ? which ecus can be read and write with the K-Tag: substantially all of? Or there are models that are not supported? :confused:
Again, thanks! :)

a strange curiosity?,but the ktag ? able to operate from bdm for the edc17?

the ago is from the can with e xxx dedicated on the pcb you have two modes of writing

[sportknight]

but from the can in serial or in bootmode?

[legendaryslave]

but from the can in serial or in bootmode?
in both cases, works in boot mede and with the ecu removed to the bench only with the first option you colleagues on the comb of the control unit, in the second option you connect directly to the pcb style edc16 bdm always in bootmode

[sportknight]

But the bootmode is a full backup?

[sportknight]

In the case of the block you are unable to restore as you do with the edc16 and the bdm?

[legendaryslave]

But the bootmode is a full backup?
you can restore only the part of the flasks + e2p always contained in the micro-a complete reading of the micro ? possible with any tool nemmno ori
only thing then do it and do a reading in the boot that would be the most complete in the case of the block edc17 always do anyway and id unless the files in any way the part is not readable, processor, then there is nothing more you can save

hello I have had a problem with a golf 6 edc16c46 at the end, did not give me even id in the boot,after a week of shaking, I managed to restore it to always boot..I assure you that communicates always ..even if id is not a number, and communicates at least with x17 and so

same my experience you can always make the id as the part of the boot record to say no ? affected by reading and writing with the tools that are currently available

[sportknight]

someone has taken the ktag from the chinese sites that now the damage on the 200 dollars? how does it behave? ? reliable?

what kind of problem did you have??

[rdponline]

The clones are always an unknown quantity, so you get the clone of the ori so you can get the clone of the clone...

good files
