Use this dialog box to specify which set of memory address ranges to be used by C-SPY during debugging.

Requirements

The C-SPY simulator.

Use ranges based on

Specify if the memory configuration should be retrieved from a predefined configuration. Choose between:

Device description file

Retrieves the memory configuration from the device description file that you have specified. See Selecting a device description file.

This option is used by default.

Debug file segment information

Retrieves the memory configuration from the debug file, which has retrieved it from the linker configuration file. This information is only available during a debug session. The advantage of using this option is that the simulator can catch memory accesses outside the linked application.

Memory information is displayed in these columns:

Zone

The memory zone, see C-SPY memory zones.

Name

The name of the memory address range.

Start

The start address for the memory address range, in hexadecimal notation.

End

The end address for the memory address range, in hexadecimal notation.

Type

The access type of the memory address range.

Size

The size of the memory address range.

Use manual ranges

Specify your own ranges manually via the Edit Memory Range dialog box. To open this dialog box, click New to specify a new memory address range, or select an existing memory address range and click Edit to modify it. For more information, see Edit Memory Range dialog box for the C-SPY simulator.

The ranges you define manually are saved between debug sessions.

An X in the column Ignored means that C-SPY has detected that the specified manual range is illegal, for example because it overlaps another range. C-SPY will not use such an area.

Memory access checking

Check for determines what to check for:

  • Access type violation.

Action selects the action to be performed if an access violation occurs. Choose between:

  • Log violations

  • Log and stop execution.

Any violations are logged in the Debug Log window.

Buttons

These buttons are available for the manual ranges:

New

Opens the Edit Memory Range dialog box, where you can specify a new memory address range and associate an access type with it, see Edit Memory Range dialog box for the C-SPY simulator.

Edit

Opens the Edit Memory Range dialog box, where you can edit the selected memory address range. See Edit Memory Range dialog box for the C-SPY simulator.

Delete

Deletes the selected memory address range definition.

Delete All

Deletes all defined memory address range definitions.
