Memory report UI

The nRF Connect for VS Code extension features the Memory report, which uses a treeview and a sunburst diagram to show the size and percentage of memory that each symbol uses on your device for RAM and ROM (and partitions, if available).

See the following sections for information about each of the UI areas. For information about the most common actions that you can do in the UI, see How to use a memory report.

Search area

This area lete you perform a live, fuzzy search for specific symbols listed in the treeview.

Tabs area

The memory report displays memory information in tabs for RAM and ROM.

A Partitions tab can also be listed, but only when a memory report has been generated for an application that contains partitions. When applicable, this area shows the addresses and sizes of partitions.

Use the Disable virtual representation button in the tab row to hide the sunburst diagram.
