1.12 SMC NAND Flash Driver - NAND Flash Read Write
This example application shows how to use the NAND Flash driver to perform read and write operations on NAND Flash device.
Description
This example uses the NAND Flash driver to communicate with the SMC based NAND Flash to perform write and read operations in Bare-Metal environment.
