Installing Windows CE and

maxDNA Software

into DPU Flash Memory

Overview

The DPU contains more than 8 megabytes of flash memory for non-volatile

storage of configuration data and associated firmware. The flash memory

contains the following:

• Core Processor’s Microsoft Windows CE operating system and

application firmware

• Input Output Module (IOM) Flash Firmware

• Complex Programmable Logic Device (CPLD) configuration data

• BIOS – Embedded BIOS and ROM Extension code

From time to time, the DPU will need to be upgraded to receive the latest

firmware updates. This chapter explains how to perform the Core Processor

and IOM upgrades. Since changes to the CPLD and BIOS require special

equipment and training, they should only be performed by qualified Metso

Automation MAX Controls Customer Care personnel.

You may upgrade Core Processor’s Windows CE operating system /

firmware and Input Output Manager Firmware via a network download or

via direct serial port download.

Note: during a CP flash, all database information is erased. Subsequently, the

DPU will restart with a blank database and require a configuration download.

Also, once a flashing operation has successfully started, it is very important

to wait for the completion of the flash process to avoid rendering the DPU

useless with no operational firmware in flash. Do not reset or remove power

from the DPU during the time it is being programmed.

WARNING – Never reset or remove power from a DPU while it is being

rogrammed.
