Thanks for the insight on rproxy.  I can verify that the unit I received
about three months ago from TI has all of the upgrades/bug fixes.

Is anyone else experiencing sync errors when trying to use rproxy w/ an
external device power supply?  This only happens if the code is running
on the uC and I try to "take over" w/ rproxy.  When I use C-Spy, it
doesn't seem to have any trouble "taking over".

Thanks
-Mark

Subject: [Mspgcc-users] FET tool problems


Hi all,

A couple of people have reported that rproxy works with some of their 
machines and not others. They suspect it is a problem with fast 
machines, due to the timing of the signals produced by rproxy. I suspect

it is a hardware issue related to the FET tool.

If you look in the user's guide that comes on CD-ROM with the FET tool, 
there is a note about a modification which should be performed. I think 
the latest FET tools should be shipped with this modification already 
implemented. However, a large proportion of the FET tools shipped to 
date need to be modified by the user. The modification improves the FET 
tool's noise tolerance. Without it most slow machines never give an 
error, but fast machines don't even reach the point where the host can 
detect the device attached to the FET tool.

Even if the IAR or Quadravox tools work and rproxy doesn't, don't assume

this means rproxy is at fault [of course it could be - just don't assume

it :-)]. I suspect rproxy drives the interface a bit faster than at 
least the older versions of the IAR software. This may just push things 
over the edge. I use a 1.8GHz P4M notebook when testing the Windows 
software, and have no trouble.

If you have a Thinkpad you should also note a modification required to 
the FET tool when used with those. Most models of Thinkpad need a 
resistor change to compensate for their unusually low drive on the 
parallel port. The MSP430 FAQ on the TI web site gives details of this.

Regards,
Steve
