Power-On-Self Test

Power-On-Self Test
The Power-On-Self-Test Program (POST) tests all EZ-KIT Mini periph-
erals and validates functionality as well as connectivity to the processor.
Once assembled, each EZ-KIT Mini is fully tested for an extended period
of time with POST. All EZ-KIT Mini boards are shipped with POST pre-
loaded into flash memory. The POST is executed by resetting the board
and pressing the proper push button(s). 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
ADSP-BF706 EZ-KIT Mini Board Support Package along with the
file that describes how the board is configured to run POST.
