Hi David,

I can run Insite on either Windows or Linux (two different hardware) to

This means gdbproxy is communicating with your target OK. It cannot
determine the device type unless the JTAG interface is functional.

Are you sure the target device is really OK?
..and "lsmod | grep ppdev" produces:
ppdev 6404 1 (autoclean)
parport 25352 2 (autoclean) [ppdev parport_pc lp]
..and "lsof | grep parport" produces:
msp430-gd 2407 dkoski 3u CHR 99,0 26956 /dev/parport0
As I said before, this is looking in the wrong area. The parallel port
must be functional. However, it might be worth looking in your BIOS, and
making sure the parallel port is set to the basic SPP mode - not ECP or
EPP. On some motherboards using ECP or EPP modes breaks some tools like
gdbproxy. On other motherboard is doesn't matter. We have never really
figured out the problem, but it may be dues to changes in the port timing.
I have also tried ddd and msp430-gdb text mode (not Insight) with the same
outcome.

Steve
