May I ask why? A driver to use it with crossworks may be useful, too
;-)
Can anyone tell me, why there is no USB-JTAG that is useable for all?
As Hardware developper you have FPGA, CPLD, C-JTAGs from several
tools and not one is compatible with the others. Why must everyone
create there own dongle. It's awful!

Guess why no one of the vendors really wants to be interoperable...
Think about something valueable...
How about money?

What sort of JTAG has IP connectivity?

The BDI2000 has, as has the Peedi.
They're offering a GDB remote interface and a telnet interface.
The OpenOCD has IP connectivity, too, it just needs to run on a Linux powered
host, for example an ARM based SBC.
I've successfully used OpenOCD on a Cirrus EP9301 based board using a FT2232
based dongle connected to the EP9301's USB host. There are endeavours to
create a uC+FPGA combination capable of running the OpenOCD, details will
follow once I know more.

Because from my understanding an N-Link is a U-Link--the hardware is to all
intents and purposes identical and the firmware is downloaded into the
device's RAM (it uses a Cypress chipset IIRC). Hence there is no IP in
software from the N-Link provider, it hitches a lift on the back of Keil's
software. So, there's no possibility to integrate into OpenOCD.

Each device has its own capabilities and limitations. You pays your

Hi guys,
I might be wrong but afaik there is one USB->JTAG that works with IAR,
Keil, Rowleys, GNU, and that would be Segger's J-Link. It also happens
to be the fastest download option I know of.
http://www.segger.com
As I said, to my best knowledge, no guarantees.

I don't understand this. With wiggler it was no problem too, why
schould it be for N/U-LINK?

I mean at least just like wiggler.

Limitation you mean. Because everyone implements only that
functionalities they needs we have to buy lot of devices with ...
> You pays your money...
much more of our money :-(
As I understood JTAG was made to make one standard interface but
there isn't really one available. Even TCP/IP-based OCD isn't
compatible with all the tools.
But as I read you go ahead with the support of Olimex-Tool. I think
this is the right way to do.

Hi Dominic,

Unterstzte Typen:
- BDM support for CPU16/32/32+, PowerPC 5xx/8xx, ColdFire
- JTAG support for ARM, M-CORE, PowerPC 4xx/6xx/7xx/74xx, PowerPC
82xx/83xx/85xx, XScale, MIPS32, MIPS64
Seems not to be a universal JTAG-Tool. Do you know whether it is
useable with all relevant tool(chain)s like keil, IAR, Crossworks...?
> The OpenOCD has IP connectivity, too,
OK, but USB woul be enoug for me. IP would have the advantage having
an isolated device.

a few hundred years ago evey manufactor uses his own standards. few
years later nearly all gains from stadardisized tools and parts. Even
cars uses them over the borders of factories. And if you needs a
screw you mostly don't have to have panic.
