µVISION DEBUGGER: Cannot enable Unlimited Trace for Cortex-M7 ETM

Information in this knowledgebase article applies to:

  • MDK-ARM all versions
  • All target devices with Cortex-M7 core


I'm using a STM32F7x board together with a ULINKpro debugger. I have enabled ETM trace and selected the Sync Trace Port with 4-bit Data trace port. But the Unlimited Trace option is always greyed out, as shown in this screenshot.

How can I enable Unlimited Trace for the STM32F7x board?


Unlimited Trace for ETM trace is not supported by µVision for Cortex-M7 devices.

That's why this option is greyed out and can't be enabled for these devices.
