In SX Microcontrollers, SX/B Compiler and SX-Key Tool, Peter Van der Zee wrote: Hi Tim; Perhaps I'm not on quite the right track as I can't exactly reproduce your results; mine works fine as long as I reprogram the SX with the debug code; that is, via "DEBUG". Could you please do exactly the following ; 1. Load your SX source program. 2. Re-program the SX by means of the "DEBUG" (left) icon. 3. Confirm that the unit has entered the "RUNNING" or "SLEEPING" states, please note which one. 4. "QUIT" the debugger. 5. At the topleft of the IDE screen predd the "RUN" button follwed by the "DEVICE" (ctrl-L) button. 6. On the pop-up "DEVICE" screen, note all active selections as well as any "grayed-out" selections. 7. Use the meory area slider to zoom down to the bottom end of memory and not if there is code located from $777 onward through $FFF. 8. Press the "READ" button to read the current contents of the SX memory. 9. Re-note all active selections as per 6. above. 10. Reconfirm the presence of code from locations $777 through $FFF as per 7. above. 11. Please report your findings for 3., 6., 7., 9., and 10. You say this problem shows up on a standard Prof. Dev. board? Hopefully we can get to the bottom of this.
