Writing one byte of data into external flash memory of NXP LPC4370 board

Hi guys,

I have a doubt. I want store one byte of data to external flash memory of lpc4370 board(LPC4370 board doesnot have internal flash, so its code is directly flash to external flash memory).
From a device i will be getting one byte of data through USB, which i need to store in the external flash memory of the LPC board.
Please note that the external flash I have is of 1MB of size and the firmware code is around 30kB(there are other function than USB communication). So, now I can use 1 byte of memory from the remaining memory of the external flash to store the data

Please help me on this
One solution I thought was using SPIFI to write data into external flash memory while code is running, but i dont know if it works and the SPIFI library v1.3. Link is not working. where can i find the SPIFI library file
