After the codec code has been programmed to the Flash memory, the code can be run in stand-alone mode,
that is, with no connection to the PC via a hardware command converter. Therefore, you can remove the
command converter connected to J3 of the EVM. You must make sure that the correct boot mode is set on
the boot mode switches at SW4. The DSP checks the pins connected to these switches (MODA-D) after
reset to determine how to boot the DSP. To boot the DSP from the Flash memory, use boot mode 9:
bootstrap from byte-wide memory, by setting the switches on SW4 to be 4 = OFF, 3 = ON, 2 = ON, and
1 = OFF.
The audio codec programming code requires music input to the EVM and a set of headphones for the
output. Connect a music source to the audio input jack at J12 using an audio interface cable with 1/8-inch
stereo plugs and connect a set of headphone to the jack at J15. Then, you simply press the Reset button,
SW1, and you can hear the music in the headphones. Now, you have successfully programmed the
DSP563xxEVM Flash memory and run the DSP in stand-alone mode using the Symphony Studio
development tools.
