Hi there,

Serial (SPI, QSPI, SPIFI) NAND flash chips seem to be relatively new (2015?)...

Witness these parts:
Winbond W25N01/02 1/2Gb (Single/Dual/Quad SPI)
Macronix MX35LF1/2 1/2Gb (Single/Dual/Quad SPI)
Micron MT291/2/4G01 1/2/4Gb (Single/Dual/Quad SPI)

All the NXP SPIFI drivers seem to be written for interfacing to serial NOR flash ICs...
Has anyone written a SPIFI driver for any of the above-mentioned chips?

I'm using the LPC1850 - want to store code and image data on SPIFI NAND flash, boot from SPIFI NAND, copy code to SDRAM on EMC, execute from SDRAM (I think).

Cheers, Chris.
