‑‑drv_debugger_cache

In this section:
Syntax
‑‑drv_debugger_cache={on|off}
Parameters
on

Enables memory caching and memory range checking.

off

Disables memory caching and memory range checking.

For use with

All C-SPY drivers.

Description

Use this option to completely disable memory caching and memory range checking in C-SPY.

Normally, C-SPY uses the memory range information in the Memory Configuration dialog box both to restrict access to certain parts of target memory and to cache target memory contents for improved C-SPY performance. Under certain rare circumstances, this is not appropriate, and you can choose Disable Debugger Cache to turn off the caching and memory range checking completely. All accesses from C-SPY will then result in corresponding accesses to the target system. Some of those circumstances are:

  • When memory is remapped at runtime and cannot be specified as a fixed set of ranges.

  • When the memory range setup is incorrect or incomplete.
