LED Blink or Talkthru Sample for CCES and ADSP-21489 EZ-Board?

I'm new to the ADSP-21489 processor, and have the ADSP-21489 EZ-board and CrossCore Embedded Studio (CCES, version 2.4.0.0). The only sample code projects I have been able to find for this combination are either too advanced for a 21489 beginner like me or are for VisualDSP++ (which I am not using).

Two questions:

1) Where can I find a simple LED Blink application for CCES and the ADSP-21489 EZ-board?

2) Where can I find a sample "talkthru" project (ideally using input from SPDIF_IN and sending output to the headphone jack) for CCES and the ADSP-21489 EZ-Board?
