Posted on July 14, 2015 at 17:01The FSMC just provides a physical interface to the NAND device. Dealing with the Reading, Writing, Erase Blocks, ECC and wear leveling stuff is all pretty much on the *developer*.
You need to read the documentation for the part you have chosen and decide if you can handle it, or not. Remember the erase blocks are generally getting larger, and your device has finite SRAM to handle that, and as the geometry of the NAND shrinks the more unreliable it is, and requires more effective/stronger ECC implementations.
A lot of the newer NAND parts can handle their own ECC syndrome generation/checking, but the correction task is still all on the microprocessor, and your software implementation.
Consider if SDIO either as MicroSD, or eMMC is a more future looking way forward.
