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

Information in this knowledgebase article applies to:

• MDK v5.x
• All target devices with Cortex-M7 core

QUESTION

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?

CAUSE

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.

MORE INFORMATION

• Refer to General Settings in the ULINKpro User's Guide.
