ARM/ARM7+ARM9 ARM Integrator

Overview

RedBoot supports both serial ports for communication and downloads. The default serial port settings are 38400,8,N,1.

The following RedBoot configurations are supported:

Initial Installation

RedBoot is installed using the on-board bootPROM environment. See the user manual for full details.

Quick download instructions

Here are quick start instructions for downloading the prebuilt Redboot image:

• Set DIP switch S1[1] to the ON position and reset or power the board up. You will see the bootPROM startup message on serial port A (J14):

• Issue the FLASH ROM load command:

  boot Monitor > L Load Motorola S-Records into flash Deleting Image 0 The S-Record loader only accepts input on the serial port. Type Ctrl/C to exit loader.

• Either use the ASCII transmit option in the terminal emulator, or on Linux, simply cat the file to the serial port:

  $ cat redboot.srec > /dev/ttyS0

  When complete, type Ctrl-C and you should see something similar to:

  ................................ ................................ .................... Downloaded 5,394 records in 81 seconds. Overwritten block/s 0 boot Monitor >

• Set DIP switch S1[1] to the OFF position and reboot the board and you should see the RedBoot banner.

Special RedBoot Commands

None.

Rebuilding RedBoot

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

export TARGET=integrator
export ARCH_DIR=arm
export PLATFORM_DIR=integrator

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