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.
