Target Run Control Issues

Cause	Solution
CPU run control is not enabled in BIOS settings.	Enable CPU run control in BIOS settings. See Target Setup.
The Intel® Boot Guard technology is enabled. It blocks CPU run control even if the latter is enabled in BIOS settings.	Disable the Intel® Boot Guard by setting the profile to 0. Use Intel® Flash Image Tool (Intel® FIT) or contact Customer Support for assistance.

After you establish the target connection and suspend and resume threads, the following message is returned in the console:

Warning - Error occurred while determining break reason for thread...

Solution: Reconfigure the target connection by specifying that the target runs an OS. See Connecting to the Target procedure, step 7 (Platform Debug Configuration).

After resuming the target, threads got suspended but no breakpoint indicator is visible (all threads are simply marked as “Suspended”).

Possible cause: If thread filtering is enabled, a breakpoint might be hit in a filtered-out (hidden) thread. That is why displayed thread show no indication of a breakpoint hit.

Cause: Buttons for target run control (like Suspend or Reset) are enabled only when a proper debug context is selected.
Solution: Refer to the Target Run Control section to identify enabling conditions for each button.
