Evaluation License Restrictions

The ADSP-21364 EZ-KIT Lite installation is part of the VisualDSP++ installation. The EZ-KIT Lite is a licensed product that offers an unre- stricted evaluation license for the first 90 days. Once the initial unrestricted 90-day evaluation license expires:

1.VisualDSP++ allows a connection to the ADSP-21364 EZ-KIT Lite via the USB Debug Agent interface only. Connections to sim- ulators and emulation products are no longer allowed.

2.The linker restricts a users program to 10922 words of internal memory for code space with no restrictions for data space.

Refer to the VisualDSP++ Installation Quick Reference Card for details.

External Memory

The EZ-KIT Lite contains three types of memory: parallel flash (1 MB), SPI flash (2 MB) and SRAM (512 Kbit). The flash memories can store user-specific boot code, allowing the board to run as a stand-alone unit. For more information about setting the boot device for the processor, see “Boot Mode and Clock Ratio Select Switch (SW10)” on page 2-12.

Table 1-1provides a map of the board’s external memory.
