John,
Thanks for the answers back. I was also able to get it to work with exactly one button on each perspective.
Oddly, there are three (3) places where you can choose this Build button:
The circles were supposed to be colored better, but I guess I am as good at Paint as I am at CCS customization.
Originally, I was checking the Build Configuration box in the small red circle in the upper left of the Customize dialog. This gave me one hammer where the blue circle is, and two on the CCS Edit perspective.
When I went to try your suggestion, I noticed you were sending me farther down in the "Available command groups" list. And I noticed there are two identical line items for "Code Composer Studio Project Build". The second one was already checked, so I swapped them, sort of matching what you said to do. This puts the hammer farther to the right as shown above in the red circle.
What are the differences between these three different check boxes, especially between the two identical ones? It would be nice to know those, but thanks for answering the real question and getting me this prized icon.
Regards,
Randy
