Chapter 3

Boot Devices and Firmware

Overview

The Kria™ KV260 Vision AI Starter Kit has a primary and secondary boot device that provides
isolation of platform-specific boot firmware from the run-time operating system and application.
This allows you to focus on developing and updating your application code within the application
image without having to rebuild and flash boot firmware. The primary boot device is a QSPI
memory located on the SOM and the secondary boot device is an SD card interface on the
carrier card. By default, the KV260 Starter Kit carrier card sets the XCK26 boot mode to QSPI32.
The SOM boots up to U-Boot using the QSPI contents and then U-Boot does a hand-off to the
secondary boot device.

Note: You must burn the SD card image and populate the SD card in the carrier card for the kit to
successfully boot to Linux.

The overall boot device definition and firmware contents are outlined in the following figure.
