LPC17xx/40xx SPIFI Flash programmer example

Detailed Description

Example description
This example demonstrates programming of the SPI flash using the SPIFI interface. The program can be run in two ways, the first and the default is having USE_SPIFI_LIB defined so that the code makes use of the functions provided by the spifi_*.lib. The second one is having USE_SPIFI_LIB not defined which will make direct calls to the boot ROM function pointers and will not use any library calls.
By default the program writes 256 bytes of data starting from hex 00 to hex FF to SPIFI_WRITE_SECTOR_OFFSET

UART needs to be setup prior to running the example as the example produces the output to the UART console. If LED1 is ON then the programming is successful, if LED2 is ON then the programming has failed.

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