26. tton menu for you to use therefore you do not need to create this configuration again After the code is downloaded to the DSP your Flash memory programming code appears in a window view below the Debug View A green highlight tells where the program counter is located in the code The green highlight should appear on the first line of the Flash memory programming code move 100 r0 You can step through the code and watch the green highlight change one line at a time You can step by using the Run gt Step Into or Step Over pull down menu clicking on the Step Into or Step Over Debug View tool bar buttons which look like yellow arrows or using the F5 and F6 function keys Now the code is ready to run There are several ways to run the code e use the Run gt Resume pull down menu e use the Resume Debug View tool bar button which looks like a green triangle e right click on the debug process list in the Debug View and choose Resume e use the F8 function key When using any of these methods the Flash memory programming code runs and it loads the codec code to the Flash memory of the EVM When the code is running control is given to the DSP therefore the windows of the debugger do not update The Flash memory programming code was written to stop automatically when it is finished and return control back to the debugger Thus when the Flash memory programming is complete the debugger windows update and you can see that the Flash memory
