2.2 NAS Controller
The AM453x implements Marvell's 88F6281 controller as the main engine of the NAS solution. The CPU has
access to two redundant SPI Flash devices from which it can boot. The CPU's RAM consists of two DDR2 2Gbit
x8 chips. For a total of 512MBytes memory.
2.3 Storage Support
The AM453x supports 1.8” Slim Solid State Drives, 2.5” SATA hard disks and 2.5” SSD.
2.4 Ethernet Switch
The switch is a Marvell 88E6131. Basic NFS NAS is available via port 0 and 1 in the Common Option Region
(Base Interface or Control Plane) or/and port 8 and 9 in the FAT Pipes Region (Fabric Interface or Data
Plane). The switch can be configured to support multiple VLANs.
2.5 RJ45 Serial Port
A RJ45 connector on the AMC faceplate provides a RS232 interface to the CPU UART0 console, or via a jumper
the serial port can be connected to the MMC B1 UART interface.
Jumper Settings:
When JP1 (5-6) is IN, the front RJ45 serial port is connected to the MMC UART B1, when the jumper
is out, the serial port is connected to CPU UART0.
