Hello,
what kind of JTAG do you use? With external power supply or only using
the current from parport? In the construction I use sometimes I have
similar problems to that ones you've described but only with parport IO
lines as power supply - with external supply it didn't happen.
You can check the voltages level & stability inside the JTAG interface
circuit to be sure whether it is possible problem source.
regards,
T.
