MON960 Support for IQ80960RM/RN 5

This chapter discusses a number of additions that have been made to MON960 to support the IQ80960RM/RN in an optional non-I2O capacity. For complete documentation on the operation of MON960, see the MON960 Debug Monitor User’s Guide . The IQ80960RM/RN evaluation platform ships with IxWorks* from Wind River Systems installed in flash firmware. To use CTOOLS and MON960 instead of IxWorks, you need to download MON960 into the onboard Flash. See Chapter 2 for more information on updating the onboard Flash. See Chapter 1 for descriptions of both IxWorks and CTOOLS.

5.1Secondary PCI Bus Expansion Connectors

The IQ80960RM/RN platform contains four secondary PCI bus expansion connectors to give users access to the secondary PCI bus of the i960® RM/RN I/O processor. Extensions to MON960 perform secondary PCI bus initialization including the establishment of a secondary PCI bus address map. Routines compatible with the PCI Local Bus Specification Revision 2.1 allow the software on the IQ80960RM/RN platform to search for devices on the secondary PCI bus and read and write the configuration space of those devices.

5.2MON960 Components

The remaining sections of this chapter assume that MON960 is installed in the onboard Flash, replacing IxWorks. The IQ80960RM/RN optional MON960 debug monitor consists of four main components:

•

Initialization firmware

•

MON960 extensions

•

MON960 kernel

•

Diagnostics/example code

These four components together are referred to as MON960.

5.2.1MON960 Initialization

At initialization, MON960 puts the IQ80960RM/RN platform into a known, functional state that allows the host processor to perform PCI initialization. Once in this state, the MON960 kernel and the MON960 extensions can load and execute correctly. Initialization is performed after a RESET condition. MON960 initialization encompasses all major portions of the i960 RM/RN I/O processor and IQ80960RM/RN platform including 80960JT core initialization, Memory Controller initialization, SDRAM initialization, Primary PCI Address Translation Unit (ATU) initialization, and PCI-to-PCI Bridge Unit initialization.

The IQ80960RM/RN platform is designed to use the Configuration Mode of the i960 RM/RN I/O processor. Configuration Mode allows the 80960JT core to initialize and control the initialization process before the PCI host configures the i960 RM/RN I/O processor. By utilizing Configuration Mode, the user
