How to use SigmaStudio boot SHARC with ADUSB2Z tools?

Hi Experts,

       I need to use SigmaStudio to control SHARC EVM with ADUSB2Z. The following is my steps:  . I am using lines connect ADUSB2Z's SPI ports with 21489EVM'S P2(DPI_P1,...SPI ports). Then I click "boot target", but the all of LEDs are lighted. It seems that DSP is not booted correctly . I rebuild the ss_app_21489 project with CCES and emulated it with JTAG, and set boot mode as SPI slave,8bit mode. What's problem cause my issue?
