ARM/StrongARM(SA1100) Intel SA1100 Multimedia Board


RedBoot supports both board serial ports. The default serial port settings are 38400,8,N,1. flash management is also supported.

The following RedBoot configurations are supported:

ROM[ROM]RedBoot running from the board's flash boot sector.redboot_ROM.ecm
RAM[RAM]RedBoot running from RAM with RedBoot in the flash boot sector.redboot_RAM.ecm

Initial Installation Method

A device programmer is used to program socketed flash parts.

Memory Maps

The first level page table is located at physical address 0xc0004000. No second level tables are used.

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).

Platform Resource Usage

The SA11x0 OS timer is used as a polled timer to provide timeout support for XModem file transfers.

Rebuilding RedBoot

These shell variables provide the platform-specific information needed for building RedBoot according to the procedure described in Chapter 3:

export TARGET=sa1100mm
export ARCH_DIR=arm
export PLATFORM_DIR=sa11x0/sa1100mm

The names of configuration files are listed above with the description of the associated modes.
