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."
Ethernet Starter Kit:
Loading NuttX with PICkit2
==========================
There are two ways to supply power to the PIC32 Ethernet Starter Kit:
NOTE: You need a PICKit3 if you plan to use the MPLAB debugger! The PICKit2
can, however, still be used to load programs. Instructions for the PICKit3
are similar.
- USB bus power connected to USB debug connector J1.
- An external application board with a regulated DC power supply that
provides +5V can be connected to the J2 application board connector
that is provided on the bottom side of the board.
Intel Hex Forma Files:
----------------------
One green LED (D3) is provided to show that the PIC32 microcontroller
is powered up.

On Board Debug Support
======================
The PIC32 Ethernet Starter Kit includes a PIC32MX440F512H USB microcontroller
that provides debugger connectivity over USB. The PIC32MX440F512H is hard-wired
to the PIC32 device to provide two types of protocol translation:
- I/O pins of PIC32MX440F512H to the ICSP™ pins of the PIC32
- I/O pins of PIC32MX440F512H to the JTAG pins of the PIC32
The PIC32 Ethernet Starter Kit currently uses the JTAG pins of the PIC32 device for
programming and debugging.
Creating Compatible NuttX HEX files
===================================

directory:

2) nuttx.ihx - This is an Intel Hex format file. This is controlled by
the setting CONFIG_INTELHEX_BINARY in the .config file.
The PICkit tool wants an Intel Hex format file to burn into FLASH.
However, there are two problems with the generated nutt.ihx:
