[quote user="Bruce McKenney47378"]I use the F5529 Launchpad routinely to program my target boards -- a number of different MCUs, most newer than the F5529. The only real difficulties I've had were ultimately traced to my target's power supply circuits -- wrong caps, bad solder joints, forgotten components. My observation (unscientific) is that some devices are more finicky about this than others.[/quote] I agree to Bruce and want to add that the target board needs a ~47K pull-up for the RST pin and should not have a cap to ground that is >2.2nF there. In addition to newer chips as target, I also tried F5529 and older chips with SBW and never had any problem. For download and debug, all I need to connect was 3.3V, Gnd, RST, and TEST. About Energia and C++, I do not see any relevance to this topic.
