Sure thing:
 

I have the SX tool Kit 45180 with SX key (usb) and I have installed SX editor

3.2.9.2h beta..I can load and run programs but the debugger doesn't work.

 

I plug the USB cord into my SXKEY

and then into my laptop...

and SXKey into the tech board...

I power up the tech board..

(no external oscillator installed)

 

I run the editor....

I open the following program (below)...Debug_demo.src (from sample programs provided)

I select debug (ctrl-d)...

It shows that it is erasing and then programming...

the debug screens open up and the status window shows "idle" at the top

I select step, walk, or run...

and they all cause the sx28 to go from idle to "sleeping" at the top

If I reset the board...it goes back to idle......

 

I have tried other basic programs with the same result...

I have tried other computers and other USB ports with the same result..

 

Parallax sent me a new SX key.... and it does the same thing..

 

I have been able to just simply run programs and they appear to work..

but I won't be able to get to far with any programming on my own if the debugger doesn't work..

;PURPOSE:       Modifies three registers to demonstrate the SX-Key's 
;               debug display.  Use Run -> Debug (or CTRL+D) to program
;               the SX, then click the Step or Poll button to see the
;               results.

;REVISIONS:
;  06/09/98 Original release.
;  09/17/04 Updated to support SASM.
;
;CONNECTIONS:
;  None.
;
;DETAILS:
;  Program the SX chip using the Run -> Debug (or CTRL+D) option.  Then
;  click the Step button to step through each instruction (taking note 
;  of the changes on screen) or use the Poll button to run full speed 
;  with updates to the display every loop iteration.  The Watch window
;  shows the values of registers IncReg, DecReg and NotReg in decimal.
;  NOTE: You must disconnect any crystal or resonator from the SX chip
;  in order to properly debug since the SX-Key will need to provide the
;  clock signal.
