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 |

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

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 http://jtag-arm9.sourceforge.net/hardware.html if you wanted usb could use an ftdichip ft245 + buffer and power it from usb |

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 Robert > On May 16, 2004, at 7:55 AM, Alex Gibson wrote: > > 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 > > http://jtag-arm9.sourceforge.net/hardware.html > > if you wanted usb could use an ftdichip ft245 + buffer and power it > from usb |
