LPC18xx/43xx SPIFI Flash programmer example

Detailed Description

Example description
This example demonstrates programming of the SPI flash using the SPIFI interface. The program will run in the SPIFI flash and will relocate the programmer to iram when the SPI flash is being programmed. 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 and the functions in the lib will be relocated to IRAM before execution, 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 hence no relocation will be done as the code directly executes from the Boot ROM area.
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.
