Hi All;

Interesting..... my situation of not being able to debug (programming at 3 volts had always been fine) did not stem from any power supply issues. Infact my setup has been identical for weeks.... same everything; an SX48 on a 40pin carrier DIP plugged into my PDB. Perhaps some minor temperature changes in the building....

Dan, eventhough your problems appear to be solved, I strongly reccommend you mess with the clock frequency and amplifier settings while in the debug mode and observe the strange goings-on.

Peter, 

 

I did play around a little, and found that changing the oscillator settings didn't affect much on my board. I will continue to play round with them as this project progresses. 

 

As an FYI, I did notice that changing the brownout setting to the 4 volt setting on the device screen caused the SX to act eerily similar to my debugging problem. :)   So, I DO KNOW there is at least one directive that will break the 3.3 volt debugging.  It's one that I'll have to keep in mind if I run into this type of issue again!  

 

Anyway, keep me posted on your troubles. If there's anything I can do to help you out, let me know! 

 

Thanks!

-Dan
