Booting From Burst Flash Memory

7-8 Getting Started with ADSP-BF548 EZ-KIT Lite

Booting From Burst Flash Memory

The BMODE0—3 input pins of the processor select the location accessed by

the processor’s boot loader at reset. On the ADSP-BF548 EZ-KIT Lite,

rotary switch

SW1 (labelled DSP BOOT) sets the values of the BMODE0—3 pins.

SW1 position 1 (default) selects the burst flash memory. When SW1 is in

position 1, every processor reset, including power-on, causes the boot

loader to start processing the contents of flash memory as a boot stream.
