Re: 555 BDM startup problem

Thanks Randall for the good suggestion. Unfortunately that didn't 
work any better. I was able to quantify the problem a bit more 
though...I can get a debug session to work if I leave the target 
power off for at least 10 minutes. Also, I was able to program a 
simple LED flashing program into the internal flash, and it works 
every time no matter how short the power cycle is, so this is 
limited to a BDM problem.
