Creating Dynamic Memory

The Create New Memory pop-up enables you to define a new Dynamic Memory file and add it to the selected batch.

To create a dynamic memory file, on the Dynamic Memory page:

• Click + New Memory. The Create New Memory pop-up appears.
• In the Name field, type a unique Dynamic Memory file name .
• Type the File ID. You can also click Locate to locate an existing File ID.
• (Optional) To import data from an existing dynamic memory file, click Locate. The Locate Memory File pop-up appears.



• For the File ID that you want to use for importing data, select the corresponding file and click Locate.

The data contained in the file is copied into the corresponding fields and any existing data is overwritten. Memory segments (if any) are added under the Memory Segments tab. To save this file, you will be prompted to use a different file name.

• Type Ref ID 1 and Ref ID 2 if any.
• In the Action drop-down list, select one of the following:
  • Set - The new data segment is added to the dynamic memory file. Existing information remains unchanged.
  • Overwrite - The new data segment will overwrite the existing information in the file.
  • Cancel - The dynamic memory file attached to the specified license is permanently deleted.
• In the Memory Type drop-down list, select one of the following:
  • Read Only: Data to be read at run-time. For example, the Product version number, text to be used in a "Welcome" message, fixed threshold values for counters, and so on.
  • Read/Write: Data that can be updated at run-time. For example, value variables for counters, information retrieved during interaction with the end user, and so on.
  • Write Once: Data that can be updated only once at run-time and then is treated as Read Only.
• Click Add Description to add description if any.
• Type File Size (maximum 33600 bytes) to specify Dynamic Memory file size.

The Memory Segments tab has the following options: New, Edit, Delete, Save, and Load.



• If you prefer to use hexadecimal definitions instead of decimal definitions to define offset locations and addresses in memory, select the Hex addresses check box.

• To define a new area in memory, click New. The New Memory Segment pop-up appears.

  

• Type a Name (maximum 50 characters).
• Type Description (maximum 250 characters) for the new memory segment. This field is optional.
• Type Text to specify value at new memory segment. This field is optional.
• Enter the Offset and Length of the new segment. You can select a Color from the palettes that will help you identify the segment.
  The field Length (bytes) accepts a value between 1 and 33600 only irrespective of the memory type selected.
• In the Text field, enter the memory data.

  You must exercise caution while entering memory data in this field. Copying and pasting data from the Sentinel LDK Toolbox may lead to data modification during the copying process.

• If you require the memory data for the New Memory Segment to be entered during Entitlement generation, select the Specify at Entitlement time check box.

When defining memory data for a Unlocked Product, you cannot specify that the data will be entered during Entitlement generation.

• Click Save. The newly defined area is displayed in the lower section of the Memory tab. The segment addresses are displayed on the left.

To edit segments and data in memory:

• To edit the offset, size, or color of a memory segment, select the segment and click Edit. Make the required changes in the Edit Memory Segment pop-up and click Save to update the changes.
• To delete a memory segment, select the segment and click Delete. The segment is deleted.
• To save a memory segment as a XML file, select the segment and click Save. The File Download dialog box appears. Save the file to a directory in your system (default file name is dynamicMemory.xml).
• To load a memory segment from a file, click Load. The Load Memory File pop-up appears. Click Browse to navigate to the directory containing the saved memory segments, select the required memory segment, and click Load. The selected memory segment is loaded.

During Product definition, a loaded memory segment overwrites any pre-existing memory in that segment.
