Debug Interface
The ADZS-21569-EZKIT provides a JTAG and Trace connection via P4 or P8.
Power-On-Self Test
The Power-On-Self-Test Program (POST) tests all EZ-KIT peripherals and validates functionality as well as connec-
tivity to the processor. Once assembled, each EZ-KIT is fully tested for an extended period of time with POST. All
EZ-KIT boards are shipped with POST preloaded into flash memory. The POST is executed by resetting the board
and connecting the USB To UART to your PC and open up a terminal window. The POST also can be used as a
reference for a custom software design or hardware troubleshooting.
Note that the source code for the POST program is included in the Board Support Package (BSP) along with the
readme file that describes how the board is configured to run POST.
Example Programs
Example programs are provided with the ADZS-21569-EZKIT Board Support Package (BSP) to demonstrate vari-
ous capabilities of the product. The programs can be found in the ADSP-21569_EZ-KIT\examples installa-
tion folder. Refer to the readme file provided with each example for more information.
Reference Design Information
A reference design info package is available for download on the Analog Devices Web site. The package provides
information on the schematic design, layout, fabrication, and assembly of the board.

Expansion Interface 3
The Expansion Interface 3 (EI3) interface supports connecting with other EI3 daughterboards designed by Analog
Devices, extending the evaluation system's capabilities. The connectors provide power, ground, reset, ADC, PPI,
TWI, UART, SPORT, SMC and GPIO signals.
The expansion interface is architected to provide support for modularity with different expansion board types. These
types fall into several categories including audio, video, converter, and asynchronous memory.
