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

QUESTION

I'm using a STM32F7x board together with a ULINKpro debugger. I have enabled the 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 the 'Unlimited Trace' option for the STM32F7x board?

CAUSE

The 'Unlimited Trace' option for ETM trace is not yet supported by µVision for Cortex-M7 devices. That's why this option is greyed out for these devices and cannot be enabled by users.
