Cant get any program to work on Pro development board brand new. I can load program into sx or at least thats what it says. but when the debug screen is open you cant use the run, walk or step buttons, and it never says idle on the status·at the top of the debug box is allways running.Is there a way to check to see if the SX-key is sending the code to the SX chip, I have a parallax USB oscilloscope. Have just about run out of solutions to fix this problem, have run all on two different computers used two diferent cables and both the SX28AC chips that were sent. e-mailed parralax support yesterday·and got no awnser·as of today·, could be·swamped. Any Help Thanks David·

    I've had that problem because I did not have DEVICE OSC4MHZ, maybe try that.

    When the debugger shows "running", very often the cause for this is a resonator/crystal in parallel with the SX-Key. Make sure that no resonator/crystal, or external clock generator is plugged in the sockets on the PDB.
