Hi,
just a question regarding the jtag interface. Chis wrote that the
pyjtag interface is connected to the PC's parallel port. Is there a
chance to connect a the msp via usb2parallel port interface? Would it
work? Would it be a big task to do the required adaptations om pyjtag?
It does not work with the existing code. If you do some work you could
make it work. However, the result would be so slow that it would be
useless. There is huge latency in USB, and the JTAG code must do
everything step by step at the parallel interface. I did a little work
on this a year ago, and realised it couldn't get anywhere.
This would allow for debugging on Macs too and on PC's if there is no
parallel port anymore in the next generation.
Fast USB debugging is in the works. The hardware tool is a little more
complex than the very simple parallel port tool, but should still be
pretty cheap. As you said, there is no choice. The parallel ports have
already disappeared from most notebooks, and they won't be on the
desktop machines for much longer.
