Hi Bruce,

Are you saying that the error I got is generated by MPSAM and not PBP?
In which order do the fuses in the 1. code, 2. *.INC file and the 3.programmer settings supersede each other? If I do not want to let the PBP automatically include the include file; where do I select this? If I remove it (the INC file) from the folder I get an error.
Anyway, which is the correct fuse for internal 4 MHz; there are a few to choose from?

Many questions, I am sorry!
