Power-On-Self Test
The power-on-self-test program (POST) tests all EZ-KIT Lite peripherals
and validates functionality as well as connectivity to the processor. Once
assembled, each EZ-KIT Lite if fully tested for an extended period of time
with a POST. All EZ-KIT Lite boards are shipped with a POST preloaded
into one of their on-board flash memories. The POST is executed by
resetting the board and pressing the proper push button(s). The POST
also can be used for reference for a custom software design or hardware
troubleshooting. Note that the source code for the POST program is
included in the development environment’s installation directory along
with the readme file, which describes how the board is configured to run a
POST.

The POST program is only available when using Vi+.
Expansion Interface II
The expansion interface II allows an Analog Devices EZ-Extender
®
or a
custom-design daughter board to be tested across various hardware plat-
forms that have the same expansion interface.
