Yes, the design is done, the schematics and source code are available on
our web site. We can supply the hardware ($99.00) assembled or bare cards
for $2.00. The software (windows only at the moment) is usable but could be
improved, ported and extended...

I guess I don't understand exactly what you are doing. Are you
designing a USB JTAG unit so that you will release the design as
open-source? The page you refer to has no data sheet or manual, only a
link for the software and schematic. Are you selling these modules? Is
the design finished yet?

Yes, we are interested ! Is this product being sold anywhere ?
We suspect that both the Raven and the Chameleon POD based their
design on the TI SN74LVT8980A JTAG TAP MASTER WITH 8 BIT GENERIC
HOST INTERFACE chip. It would not be too dificult to interface
this chip (plus a clock generator) with an EPP or ECP compatible
parallel port. We even found a VHDL model for this chip.
But in the long run a USB interface is more flexible.
Macraigor already launched a USB pod and as Mr. Laurent Gauch
told us Amontec will also launch one.
Best regards,
Claudio L. S.

If you are interested, We can supply a USB - JTAG DONGLE for free. This
is an open design with GPLed hardware and software. It supports JTAG
clocks up to 48 MHz, 5V, 3.3V and 2.5V JTAG VIO. It uses a small FPGA
for all logic other than USB interface, so is very flexible. The
architecture supports efficient access to small sections of the JTAG scan
chain (4096 bits max currently) so should be quite fast for generic
flash programming tasks. The fpga config is downloaded via USB when the
dongle starts up. There is a SVF player and a BIT player provided for
configuration of Xilinx CPLDs and FPGAs. Any hardware or software help
for more devices/platforms is welcome!

...
Are you interested by the Raven interface, or by speed-up your JTAG
interface ?
I can do a version a little bit more faster than the original RAVEN. But
this new config will be *not* compatible with the original Raven Dongle.
I will provide the interface specification for FREE. So you will be
abble to speed-up your JTAG interface using our low cost Chameleon POD.
So let me know if you (and other poeple on this group) are interested by
a new 'go-faster' JTAG configuration.
The deal : Amontec provides the hardware, and you provide the software !

Hi Claudio,
Sorry, but we cannot give you any info on how the Raven interface is.
Why, because we have to protect our design and our know-how. The Raven
interface is a complexe state-machine (parallel-to-serial) with baudrate
control, with auto-detection mechanism, with test mode, with some JTAG
and EPP tips.
Amontec is working on an new Chameleon POD version: xUSB POD version.
We want to reuse the Raven know-how and to add USB messaging support
(USB based on 8051). The goal is to provide an new JTAG solution close
to the Abatron BDI, but cheaper and fully based on logic programmable
(very generic).
We are thinking to provide an open-source interface version of our xUSB
POD version.
But anyway, we cannot give you any info on the Raven interface. Sorry. I
hope you will understand.
Best Regards,
Laurent Gauch

Hi all,
We have already developed a flash programmer using a
wiggler compatible JTAG interface, directly manipulating
the JTAG pins (TCK, TDI, TDO, TMS) through the parallel
port.
We would like to speed up the process using a Raven
compatible interface (actually we have a Chameleon POD).
We haven't found any documentation about the interface
of this device with a parallel port.
Perhaps Mr. Laurent Gauch from AMONTEC could send some
information about it. I bet it will also interest other
people in this group.
Regards,
Claudio L. S.
