Document Number: LS2085ARDBFS REV 1

The LS2085A reference design is designed

in a 1U form factor and will conform to all

requirements for sale worldwide, including

certifications for FCC Part 15 Class A.

The QorIQ LS2085A RDB comes pre-loaded

with Freescale’s board support package

(BSP) based on standard Linux kernel. The

comprehensive BSP also enables some of the

SoCs new capabilities:

• LinuxkernelsupportforDPAA2containers.

• DPAA2L2switchobjects

• NADK,aLinuxuserspaceenvironment

providing functions and interfaces oriented

towards packet processing applications

• Supportforanopenarchitectureparallel

processing packet engine

Hardware Features:

• LS2085ACPUUpto8xARMCortex-A57

CPU, up to 2.0 GHz core speed

• Memory

SDRAM Supporting dual ranked DIMM

slot, two x DDR4 uDIMM x72 support

for 4 GB memory per slot, 2.1 GT/s data

rate, ECC enable

Support for an additional dual rank

uDIMM slot. One x ½ uDIMM x40

support for 1 GB memory, 1.6 GT/s

data rate

128 MB NOR flash, 8-bit

2 GB SLC NAND flash

• PCIExpress

One standard slot x8 PCIe connector

to support 1 x8 PCIe Gen3 or 2x4 PCIe

through a connector

• USB3.0

Two USB type A connectors on the front

or rear panel connected to a USB PHY;

one configured as a host, the second

as OTG

• SATA

Support for 2xSATA connectors. These

will be muxed from the PCIe SERDES

and configured through a switch on

the board

• Ethernet

Support for up to 4-ports of 10 GbE,

SFP+

Support for up to 4-ports of 10 GbE,

copper (4xRJ45)

Available CodeWarrior tool chain

• Fullyintegratedmarket-readysolutionsthat

integrate Freescale-supplied datapaths (i.e.

IP forwarding, IPSec, Netflow, BFD, SDN,

ETh OAM and many other networking

functions and protocols)

Users may also integrate these advanced

packet processing datapaths themselves
