An HP E3458A Processor Probe can be connected through the
HP E2480A to the target system. This eliminates the need for
target-system connectors for run control. The processor probe allows
the user to halt execution, download code, read/write memory and
registers, and step through software. Example connections of a
processor probe are shown in the typical setups on the next pages.
The procedure for connecting a processor probe is given at the end of
Chapter 2.
The E3458A Processor Probe is provided with a graphical user
interface running on the HP 16505A Prototype Analyzer. You can
control target system operation directly from the HP 16505A.
Registers and memory can be displayed and modified. Target code
can be displayed in assembly language.
The E3458A graphical user interface is used to configure the E2480A
preprocessor interface for address reconstruction. Configure the
preprocessor as follows:
1 If the target system contains initialization code, run the target system
until initialization of the SIM registers is complete. The target
processor can be stopped by using a software breakpoint or with the
"break" button.
2 Press the "Read Configuration" button in the processor probe
"Configuration" window."
3 Press the "Load Preprocessor" button in the "Configuration" window.
The preprocessor interface is now ready for address reconstruction.
If your target system does not contain initialization code, manually modify
the SIM register values in the "Configuration" window according to your
target system specification. Then repeat Step 3, above.
