Flash

The Storage of MCC-AM335X-Y have two type, eMMC or NAND Flash, they are Pin-compatible. Default, the NAND Flash are pasted.

When using the NAND Flash, a single MLC Flash Chip is connects to GPMC of AM335x, the size is 256/512MB. 8-Bit IO, and other control singals.

The eMMC is a communication and mass data storage device that includes a MMC interface, and a controller on an advanced 11-signal bus, which is compliant with the MMC system specification.

It simplified the design, to solve the problems of compatibility. When using eMMC, it connected to MMC1 of AM335x, 8 data line, cmd and clk line like mmc. The size is 2GB.
