Ktag, and Jtag

[bart]

I would like to ask a question, even if probably for many the answer ? granted...
What? the difference between Ktag and the Jtag?
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...

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?

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

With a bit of delay, but 1000 thanks to all for the explanations received. Now ? much more? clear
A doubt that I ? built by reading the answers ? what ecu you can read and write with the K-Tag: substantially all of? Or there are models that are not supported?
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
