Unable to Halt the CPU

Possible issues and solutions:

Warning Returned after Halting and Resuming the CPU

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).

Unable to Identify why Threads Got Suspended

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.

Unable to Use Buttons for Target Run Control

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.
