Downloading a configuration

The HP E2480A is shipped with all reconstruction disabled. This

preprocessor configuration provides accurate analysis when A[19:23],

FC[0:2], SIZ0, SIZ1, DSACK0, and DSAK1 are valid. If your target system is

configured differently, you must configure the preprocessor to match your

target system configuration.

To configure the preprocessor, the HP E2480A must be connected to an

HP E3458A Processor Probe. The processor probe must be connected to a

computer via LAN or RS-232-C. The HP E2480A preprocessor may be

configured from either an HP approved debugger or the HP 16505A

Prototype Analyzer. For a list of HP approved debugger vendors, contact

your HP Sales and Service office.

Configuring With a Debugger

Using a debugger, there are two methods of configuration. The first method

requires values to be manually written into SIM/SCIM registers MCR, PEPAR,

CSPAR0, CSPAR1, and the CSBARx and CSORx of all chip selects being

used. The second method requires code to be loaded into the target,

performing a "reset" and "run", then performing a "break" after the SIM/SCIM

registers have been configured. In either case, once the SIM/SCIM registers

are configured, telnet to the processor probe (HP E3458A) and perform

"sync sim" and "pp load". This will place information needed by the

preprocessor for configuration in the preprocessor non-volatile memory.

Configuring With the HP 16505A Prototype Analyzer

Using the HP 16505A Prototype Analyzer, move the uP run control icon into

the workspace, click the right mouse button and select "Start Session"’. A "uP

run control" window should appear. In the "Processor Probe LAN Name"

field, place the LAN name of the HP E3458A connected to the target of

interest and click "start session".

When a connection is established, an "Information" window should appear

indicating connection success. Click on "OK". Another window, "run control"

should also appear. Under the "Window" pull-down menu, select

"Configuration". Two windows should appear, "Configuration" and

"Error/status log".

Using the "Configuration" window, there are two methods of preprocessor

configuration. The first method requires values to be manually written into

SIM/SCIM register fields MCR, PEPAR, CSPAR0, CSPAR1, and the CSBARx
