Many thanks for the hints!

For a usb version, how would that work driver-wise? Would the generic
drivers supplied by ftdichip be recognized by Codewarrior?

best regards

The newmicros jtag works well.

Its easy enough to build your own if you
have the time, otherwise New Micros will work out of the box.

Most of the parallel port to jtag connectors are just a 74hc244
buffer + sockets

if you wanted usb could use an ftdichip ft245 + buffer and power it
from usb

I have been using the JTAG-Cable-14P from New Micros http://www.newmicros.com for months now without a problem.  I've used it with Codewarrior on a DSP56858EVM and our custom design using a DSP56858.  It is reasonably priced at $25US and well worth it.
 
Good luck,
Louis

Subject: [motoroladsp] jtag command converter

Hello

Would anyone be able to recommend an economical JTAG command converter, either to
USB or parellel (printer port) for use with Metrowerks Codewarrior on a 568000/E device?
Or what is the simplest design to make ones own?
The evaluation boards from Motorola incorporate various designs on-board, allowing both
5 V and 3,3 V levels on the printer port side and requiring two octal buffers to achieve the
translation -- is that really needed?
Don't all current printer ports work on the same 5 V level?

Many thanks!
Robert Imhoff
