Freescale MPC837xE-RDB Board
-----------------------------------------

1. Board Description

The MPC837xE-RDB are reference boards featuring the Freescale MPC8377E,
MPC8378E, and the MPC8379E processors in a Mini-ITX form factor.

The MPC837xE-RDB's have the following common features:

A) 256-MBytes on-board DDR2 unbuffered SDRAM
B) 8-Mbytes NOR Flash
C) 32-MBytes NAND Flash
D) 1 Secure Digital High Speed Card (SDHC) Interface
E) 1 Gigabit Ethernet
F) 5-port Ethernet switch (Vitesse 7385)
G) 1 32-bit, 3.3 V, PCI slot
H) 1 32-bit, 3.3 V, Mini-PCI slot
I) 4-port USB 2.0 Hub
J) 1-port OTG USB
K) 2 serial ports (top main console)
L) on board Oscillator: 66M

The MPC837xE-RDB's have the following differences:

MPC8377E-RDB MPC8378E-RDB MPC8379E-RDB
SATA controllers 2 0 4
PCI-Express (mini) 2 2 0
SGMII Ports 0 2 0

2. Memory Map

2.1. The memory map should look pretty much like this:

Address Range Device Size Port Size
(Bytes) (Bits)
=========================== ================= ======= =========
0x0000_0000 0x0fff_ffff DDR 256M 64
0x1000_0000 0x7fff_ffff Empty 1.75G -
0x8000_0000 0x8fff_ffff PCI MEM prefetch 256M 32
0x9000_0000 0x9fff_ffff PCI MEM non-prefetch 256M 32
0xe030_0000 0xe03f_ffff PCI I/O space 1M 32
0xe000_0000 0xe00f_ffff Int Mem Reg Space 1M -
0xe060_0000 0xe060_7fff NAND Flash 32K 8
0xfe00_0000 0xfe7f_ffff NOR Flash on CS0 8M 16
