Firmware

Introduction

 PPC/PMC-8260/DS1

4 - 3

 

Introduction

Motorola provides a firmware with the  PPC/PMC-8260/DS1 which is executed 
immediately after power up. It performs a power-on self-test (POST) and a basic 
hardware initialization so that all devices are accessible. If you have created a 
driver for the host board with the help of this chapter, it furthermore enables com-
munication between the PMC module and the carrier board.

Code examples are given in the “Code Examples” section on page 4-30. 

Features

The firmware offers a number of features:
•

Execute POST and store POST results in the POST result storage area

•

Execute application software from boot flash device

•

Start primary booter to:
– Load application software via PCI bus
– Program application software into the boot flash device 
– Read from and write to all devices on the  PPC/PMC-8260/DS1
– Obtain detailed results from the power-on self-test to evaluate error condi-

tions

•

Controlling and monitoring the boot process

Resources Used by the Firmware

The PMC8260/DS1 firmware uses the following resources:
•

Firmware is stored in the boot flash at offset 100

16

, and occupies the first 256 

KByte. This leaves 1.75 MByte for application usage.

•

Mailbox registers 5, 6 and 7 of the PowerSpan II PCI bridge as control and sta-
tus registers.

Note: In order to avoid firmware malfunction, do not use the mailbox regis-
ters 5, 6 and 7 of the PowerSpan II since they are used by the firmware.
