µVISION: Why is the EVR (Event Recorder) variant missing under STDOUT?

Information in this knowledgebase article applies to:

  • MDK-ARM v5.22 or later
  • ARM Compiler pack v1.2.0 or earlier


After the setup of the Event recorder, one optional step is to redirect printf output to the Event Recorder. A picture in the guide shows a dropdown list containing "EVR". However, the dropdown menu in my IDE only shows the options: Breakpoint, User, and (on some devices) ITM. Why is the EVR option missing?


The EVR component variant (Variant) is not available in earlier ARM Compiler packs.


Use the Pack Installer to upgrade to ARM Compiler pack v1.3.0 or later. Then use the "Select Software Packs" dialog to enable the new pack. To open this dialog, use the funnel icon, next to the Pack Installer icon.
