LPC17xx/40xx External NAND Flash tests

Detailed Description

Example description
The Flash example shows how to use external NAND Flash using EMC.
The example allows you to place a small string in a sector of the Flash and the string will remain across reset cycles. No attempt at ECC is made in this example (which is required for data reliability for NAND FLASH).

To use the example, connect a serial cable to the board's RS232/UART port and start a terminal program to monitor the port. The terminal program on the host PC should be setup for 115K8N1.

Special connection requirements
JP2: 3-4 is ON
