SmartWare Software Configuration Guide 5 • System image handling

Introduction

This chapter describes how to load, maintain, and update the various software images in the SmartNode. The

SmartWare system software consists of the application image and the driver images. The images are stored in

persistent (non-volatile) memory. The application image is the software which actually operates the

SmartNode. Driver images are used to operate the various optional PMC interface cards.

This chapter includes the following sections:

• Memory regions in Smartware

• System image handling task list (see page 67)

• Boot procedure and bootloader (see page 73)

Note Section “System image handling task list” on page 67 describes the standard

way to upgrade the SmartWare. If you encounter problems that won’t let you

upgrade using the standard method, refer to section “Factory conﬁguration”

on page 74.

Note Refer to appendix F, “Notes for upgrading from R3.10 to R3.20” on

page 618 for information on converting from SmartWare release R3.10

to R3.20

• Factory conﬁguration (see page 74)

Patton SmartNode devices are shipped with default system software which is stored in persistent memory.

Along with the default system software (application image and driver images), a factory conﬁguration, factory-

conﬁg, has been loaded into the SmartNode at the factory. This conﬁguration ﬁle sets the initial basic operating

parameters of the SmartNode, such as enabling the Ethernet ports, setting the default IP addresses and the

DHCP server.

Other conﬁguration ﬁles may be stored in the SmartNode persistent memory. A conﬁguration ﬁle is an ordered

list of commands. Some of the various conﬁguration ﬁles are

• factory-conﬁg (read-only)

• startup-conﬁg

• running-conﬁg

• user-conﬁg1, user-conﬁg2, etc. (these are speciﬁc application conﬁgurations created by the user)

Backups of the conﬁguration ﬁles can be stored on a remote trivial ﬁle transfer protocol (TFTP) server. The

remote tftp server must be accessible via one of the SmartNode IP interfaces. Tftp cannot be used from the

console interface.

The following sections focus on SmartWare memory regions, as well as the software components you can copy

into the memory or move between a TFTP server and the memory of the SmartNode. As SmartWare uses a

speciﬁc vocabulary in naming those software components, refer to appendix A, “Terms and deﬁnitions” on 635

to ensure that you understand the concepts.
