	---help---
		Select where you will connect the console.

		Virtual COM Port:

		Advantage: Use the ST-Link as a console. No Extra wiring
		needed.

		Disadvantage: Not the best choice for initial bring up.

		BOARD USART Connector:

		Advantage: You have a shield so it is easy.

		Disadvantage: You loose the use of the
		other functions on PA9, PA10

		Create the MTD driver for the GD25 and "wrap" the GD25 as a standard
		block driver that could then, for example, be mounted using FAT or
		any other file system. Any file system may be used, but there will
		be no wear-leveling.

		Create the MTD driver for the GD25 and mount the GD25 device as
		a wear-leveling, NuttX FLASH file system (NXFFS).  The downside of
		NXFFS is that it can be very slow.
