18. EVM Resets  CCS reset  Use most commonly – fast and easy  Invoked via: Debug -> DSP Reset  Resets DSP (not full board)  May not clear all states required for ‘clean’ new debug session  Reset button  More extensive reset operation, still not comprehensive  OK to assert when CCS (3.1 or higher) is running  Absolute reset  Provides completely ‘fresh’ starting point  Disconnect CCS from target : C  Remove Power and USB plugs  Re-connect CCS to the target : C  Best choice to be sure a full reset is obtained D SP TEXAS INSTRUMENTS TECHNOLOGY 18
