SPI FLASH programming algorithm for the DFU Utility

Detailed Description

Example description
This programming algorithm allows upload and download of data to and from SPI FLASH storage on LPC18xx and LPC43xx devices.

More information on using the DFU Utility can be found at the following links:
DFU Utility information
DFU Utility production programming API

Special connection requirements
There are no special connection requirements for this example.

Build procedures:
LPC18xx/43xx example quickstart for Keil uVision4

Supported boards and board setup:
Although this example includes a build target for only the Keil 1857 board, it should run on all 18xx or 43xx boards.
Keil 1857 evaluation boards
