[Mspgcc-users] jtag problem

[David S. <sm...@am...>]

Greetings,

One machine works, the other doesn't.  I'm looking for clues as to what
might be different.  The problem is failure of msp430-jtag.

Here's the output:
ns2@thevenin:~/c_code/msp430/ns2$ make flash

-----------------------------------------------------------

That's the error I get on the machine that works if the parallel port
isn't plugged in, so I'm assuming its a parallel port error.  I have
lpd stopped, and have the same /dev/parport0 setup as on the working
machine.

I suspect some python backend or libraries are different, but don't
know what to look for.

The machine that works is running: Linux watt 2.6.8-3-686-smp #1 SMP
Thu May 25 00:54:20 UTC 2006 i686 GNU/Linux

The one that fails is running: Linux thevenin 2.4.18-686 #1 Sun Apr 14
11:32:47 EST 2002 i686 GNU/Linux
