Memory Maps
RedBoot sets up the following memory map on the Ocelot board.
Note that these addresses are accessed through kseg0/1 and thus translate to the actual address range 0x80000000-
0xbfffffff, depending on the need for caching/non-caching access to the bus.
NOTE: The virtual memory maps in this section use a C and B column to indicate whether or not the region is
cached (C) or buffered (B).
Physical Address Range Description
----------------------- -----------
0x00000000 - 0x0fffffff SDRAM
0x10000000 - 0x10ffffff PCI I/O space
0x12000000 - 0x13ffffff PCI Memory space
0x14000000 - 0x1400ffff Galileo system controller
0x1c000000 - 0x1c0000ff PLD (board logic)
0x1fc00000 - 0x1fc7ffff flash
Rebuilding RedBoot
These shell variables provide the platform-specific information needed for building RedBoot according to the
procedure described in
Chapter 3 :
export TARGET=ocelot
export ARCH_DIR=mips
export PLATFORM_DIR=rm7000/ocelot
The names of configuration files are listed above with the description of the associated modes.
MIPS/VR4375 NEC DDB-VRC4375
Overview
RedBoot supports only serial port 1, which is connected to the upper of the stacked serial connectors on the board.
The default serial port settings are 38400,8,N,1. FLASH management is also supported.
The following RedBoot configurations are supported:
