it requires ppdev and i think thats only available in kernel 2.4+ maybe you need to load that first. and the device names are probably different. you need a "/dev/parport0" if you don't have that, make a link "ln -s /dev/youdev /dev/parport0" >This seems to come from within the _parjtag.so module, so I can't easily >probe around to see what it means.

By next year it looks like there will be no serial and >parallel ports on new PCs, and only USB will work. yes the future looks dark for hobby projects ;-) i think that our serial-JTAG hardware work with serial_USB convertors together, so it isn't realy that big problem, but its an inconvenience. >Also, is the >intention to manufacture a batch of PCBs for this, and make all our >lives easy? not yet. i would wait until the second generation firmware is working and tested, before ordering a bunch of PCBs. i have a layout (in Eagle) and i have made prototypes which work (altough those were with Protel. I have reworked it in Eagle, so that should be the same) chris
