Adopting USB2Wiggler hardware

Adopting USB2Wiggler hardware

Adopting USB2Wiggler hardware

There is used USB2Wiggler device for OnCE interface, it has small internal daughter board labeled COP-OnCE that adapts it to a ONCE pinout. I wanna know is it possible to adopt this USB2Wiggler hardware for ARM and MIPS JTAG interfaces.
Can this hardware be configured for JTAG debugging interface by opening the cover, removing the "COP-OnCE" adapter PCB, and putting the target ribbon cable on P6 or P4? (20 or 14 pin JTAG) Can hardware also be used for MIPS interface by connecting cable to P4?
Here is pictures.

RE: Adopting USB2Wiggler hardware

The JTAG interfaces that I've used in the past were nothing more than parallel port ('Centronics' printer) cables with the require JTAG pins on the other end.

I'd start with your JTAG software (running on your PC or laptop) and see what the associated documentation calls up; what cable/hardware does it need? It might be a lot simpler than what you're contemplating.

RE: Adopting USB2Wiggler hardware

Why not have purchasing just buy the correct JTAG unit rather than going through the complicated (and often not viable) process of changing one meant for another processor? Who wants to write driver software just to get the real work done...

Because it's expensive, and will use it only occasionally, just have very limited budget. Only wanted to figire out is it possible adopt it this way or not.

RE: Adopting USB2Wiggler hardware

$250 is pretty low for a good JTAG unit, actually. If you have to ask what's involved in making the change, it's a guarantee you will spend WAY more than the cost of the JTAG unit in man hours making the modification.
