Creating debug hardware target configurations5.21 Configuring SecurCore behavior if <strong>the</strong> processor clock stops when steppinginstructionsIf a step instruction operation fails, you must consider <strong>the</strong> configuration setting No error ifstep-instr can’t stop (NO_ERROR_ON_STEPRUN).This configuration item controls <strong>the</strong> generation of error messages if a step instruction (stepi)operation fails because of a timeout attempting to stop <strong>the</strong> processor after a step is complete.This can occur on <strong>the</strong> SecurCore if an instruction execution results in <strong>the</strong> processor clock beingdisabled through CLKEN. The processor appears to be in a running state. If you use <strong>the</strong> defaultsetting of True, no error appears if an instruction step results in <strong>the</strong> processor running. If you set<strong>the</strong> item to False, an error dialog appears in your debugger.5.21.1 See alsoTasks• Configuring TrustZone enabled processor behavior when debug privileges are reduced onpage 5-39.Reference• <strong>Debug</strong> hardware Advanced configuration reset options on page 5-37.<strong>ARM</strong> DUI 0498F Copyright © 2010-2012 <strong>ARM</strong>.
