4) Launch the batch file 00-OpenOCD.bat, which establishes the host PC to JTAG debugging connection. (Note: Sometimes OpenOCD is not always able to connect to the DSP after the board is freshly powered up and has been freshly connected to the host PC.)

2) Double-click the file makefile.txt (or whatever filename for the map file was used in the project) to open it with the editor. Under the P: Memory heading, look for the section name soundbite_eeprogram. Make note of the start address for this section. 3) Launch the External Tool configured for the Symphony SoundBite.
