ADSP-BF506F EZ-KIT Lite Evaluation System Manual

1-9

Using ADSP-BF506F EZ-KIT Lite

By default, the EZ-KIT Lite boots from SPI flash memory. The processor

boots from internal parallel flash memory if the boot mode select switch

(SW2) is set to position 1 or 2; see “Boot Mode Select Switch (SW2)” on

page 2-8.

Flash memory code can be modified. For instructions, refer to the online

Help and example program included in the EZ-KIT Lite installation

directory.

SPI Flash Memory Interface

SPI flash memory of the ADSP-BF506F EZ-KIT Lite is a 16 Mb Num-

onyx M25P16 device. The device is selected via SPI0_SEL1.

SPI flash memory is pre-loaded with boot code for the power-on-self test

(POST) program. For more information, refer to “Power-On-Self Test”

on page 1-9.

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

pre-loaded into one of their on-board flash memories. The POST is exe-

cuted 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 hard-

ware troubleshooting. Note that the source code for the POST program is

included in the VisualDSP++ installation directory along with the

readme.txt file, which describes how the board is configured to run a

POST.
