Management Processor Monitor

The ATCA-9305 monitor is based on the Embedded PowerPC Linux Universal Boot (U-Boot)

Project program, available under the GNU General Public License (GPL). For instructions on

how to obtain the source code for this GPL program, please visit http://www.emersonem-

beddedcomputing.com/post-sales_support/218, send an e-mail to support@arte-

syncp.com, or call Emerson at (800)327-1251.

This chapter describes the monitor’s basic features, operation, and configuration

sequences. This chapter also serves as a reference for the monitor commands and func-

tions.

The ATCA-9305 monitor uses a command-line interface with the following features:

Auto-Repeat: After entering a command, you can re-execute it simply by pressing the ENTER or RETURN

key.

Command History: Recall previously entered commands using the up and down arrow keys.

TFTP Boot: You can use the TFTP protocol to load application images via Ethernet into the ATCA-9305’s

memory.

Auto-Boot: You can store specific boot commands in the environment to be executed automatically

after reset.

Flash Programming: You can write application images into flash via the U-Boot command line. The upper 1 MB at

the base of flash and 128 KB of each flash bank is reserved for the monitor and environment

variables (see “MPC8548 Memory Map”). One megabyte is reserved at the second bank of

flash. The moninit command will load both banks of flash (see “moninit” on page9-22) with

the monitor and default environment variables.

At power-up or after a reset, the monitor runs diagnostics and reports the results in the

start-up display, see Fig.9-1. During the power-up sequence, the monitor configures the

board according to the environment variables (see “MPC8548 Environment Variables” on

page9-26). I f the configuration indicates that autoboot i s enabled, the monitor attempts to

load the application from the specified device. If the monitor is not configured for autoboot

or a failure occurs during power-up, the monitor enters normal command-line mode. Also,

the optional “e-keying” environment variable enables connections at power-up, for debug

purposes only, to the Update Channel and payload ports that go off the ATCA-9305. See

Table 9 -7 for more information.

The monitor command prompt in Fig.9-1 is the result of a successful hardware boot of the

ATCA-9305.
