If you have problems with the dependency build (for example, if you are not
building on C:), then you may need to modify tools/mkdeps.sh
Powering the Board
==================
"Power can be supplied to the Multimedia Expansion Board through the DC
connector located on the Multimedia Expansion Board... By connecting
9-14V power supply to the DC connector, the Multimedia Expansion Board
and starter kit will receive the proper voltages. The user can also
supply power via the starter kit. However, if the application uses
multiple features of the Multimedia Expansion Board, it is recommended
to use 9-14V power supply."
Loading NuttX with PICkit2
