I had the problem with the ghosted out Walk, Run, Step for a few days.  I solved it yesterday, but I'm not sure how.  In my case, I adjusted the oscillator to OSCHS3 and the frequency to 50Mhz.  For some reason, this got it working again.  I did notice that I one of the power supply filter capacitors had come out on my breadboard.  So, maybe the power was fluctuating?  I have no idea.  I had some problems before with the SX key when I didn't have the power stable at 5VDC.  This is probably not helpful except for the fact that I'm sympathetic since I just had this problem.  I can use the debug now.

BTW, I'm new to this whole SX-Key thing. I can't figure out to to store and run a program after I disconnect the power from the SX-Key and chip.  I'm learning about this whole process from the fine book, "Beginning Assembly for the SX Microcontroller."   I can go through the examples just fine.  However, I have to load and run the program from the program every time to run it.  I can also ground the reset pin and that will restart the program.  However, when I disconnect the power and then reconnect it, the program doesn't run again automatically on power on.  Is there something I need to do?  I don't have an external clock.  I'm using the clock on the SX-Key.
