Yes, these ribbon cables appear to suffer from severe crosstalk at times. I've also had reports from a friend about similar figures. Just keep the ribbon cable short then. Put some isolating foil around the Dragon itself, so you can place it close to the target. The ribbon cable of the JTAG ICE (that fragile white stuff) is a little longer (23 cm), but it's got extra shielding wires between each data wire, so it doesn't appear to be a problem. Maybe it's also due to their drivers being a little more robust and/or faster, at least I've never encountered that kind of issues with a genuine ICE. -- cheers, J"org .-.-. --... ...-- -.. .
