Initial Setup
Powering the Starter Kit and Power Budgets
The Kria™ KV260 Vision AI Starter Kit requires a 12V, 3A power supply adapter to power the kit.
Note: The power supply adapter is not included in the KV260 Starter Kit. The following table lists the
suggested power supply adapter that must be purchased separately.
Table 3: Power Adapters to Purchase for the KV260 Starter Kit
Vendor Model Description
CUI Inc. SMI36-12-V-P6 +12V, 3A DC adapter using a center-pin positive barrel connector (2.5 mm ID,
5.5 mm OD)
The power supply adapter barrel connector plugs into the DC jack (J12) to supply the +12V
power source to KV260 Starter Kit.
Powering the K26 SOM
• The KV260 Starter Kit carrier card on-board regulator generates a 5V supply and provides
power to other voltage regulators.
• The SOM power rail (VCC_SOM) is powered by the 5V supply.
• Next, the SOM on-board power-on sequencing starts.
• The carrier card provides the programmable logic (PL) the VCCO voltage rails aer the SOM
asserts the VCCOEN_S_M2C and VCCOEN_PL_M2C signals
Power Telemetry
A power monitor device is available on the SOM power rail (VCC_SOM). You can access the total
power consumed by the SOM module through the I2C bus and Xilinx provided ulies.
Powering Peripherals
The KV260 Starter Kit carrier card supplies power to the I/O peripherals as specied by the
following interface specicaons.

USB3.0
There are four USB3.0 interface ports available on the KV260 Starter Kit carrier card. Each port
can deliver a 5V supply to the aached I/O peripherals with up to 900 mA per port. All ports are
protected against an over-current event through individual 900 mA power switches per port.
Note: The total current (across all four ports) is allocated at 2.1A.
Pmod Connector
The Pmod interface (from Digilent Inc.) is supported by the 3.3V, 100 mA capacity on the supply
pin.
Raspberry Pi Camera Interface
The Raspberry Pi camera 15 pin interface connector is supported by the 3.3V supply voltage on
the supply pin.
IAS Module Connector
The SOM supports two IAS module connectors, as dened by the ON Semiconductor IAS
module denion standard. The KV260 Starter Kit carrier card provides 2.75V, 1.8V, and 1.2V
supply rails on specied power pins.
Fan and Heat Sink
The KV260 Starter Kit is built with an integrated acve cooling soluon (see Figure 2). The
integrated fansink allows you to exercise the full 10W Zynq® UltraScale+™ MPSoC applicaon
power budget without any addional accessories.
Out of the box, the 12V fan should already be plugged into the starter kit. If it is not, be sure that
the fan is plugged into the connector designated in Table 2. The fan connector is keyed to ensure
proper orientaon.
By default, the fan runs at a constant speed. Variable fan speed control can be implemented
through a FPGA based PWM fan controller. The fan gang signal is connected to a FPGA HD I/O
bank pin for control. Consult the corresponding KV260 Starter Kit carrier card schemac for
specic pin assignment and Xilinx SOM source code repositories for an RTL implementaon that
can be integrated with your design.

Chapter 3
Boot Devices and Firmware
Overview
The Kria™ KV260 Vision AI Starter Kit has a primary and secondary boot device that provides
isolaon of plaorm-specic boot rmware from the run-me operang system and applicaon.
This allows you to focus on developing and updang your applicaon code within the applicaon
image without having to rebuild and ash boot rmware. 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-o 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 denion and rmware contents are outlined in the following gure.

Primary Boot Device
The primary boot device is a QSPI device located on the SOM. The necessary elements are
packaged in a Zynq® UltraScale+™ MPSoC specic format and le captured as BOOT.BIN. The
BOOT.BIN le contains the board-specic boot rmware that consists of the following elements:
•FSBL: First-stage boot-loader rmware
•PMU: Plaorm management unit rmware
•ATF: Arm® trusted rmware
•U-Boot: Second-stage boot loader
U-Boot provides the funconality for the hand-o between the primary boot device and the
secondary boot device. It will search for both the SD card and eMMC secondary boot devices; if
both are detected it will provide a menu interface to you to select the desired Linux boot target.
The primary boot device provides a redundant copy of boot rmware arranged in an A/B
conguraon. The A/B conguraon provides a dynamic primary and secondary image operaon
with corresponding update mechanisms. On boot, the system automacally boots from the
dened primary image, and, if boot fails, it falls back to the previously known good boot image.
Secondary Boot Device
The secondary boot device on the KV260 Starter Kit is the SD card. It contains the operang
system image and associated applicaon les. The KV260 Starter Kit accelerated applicaon
references are built on the Linux operang system. The Geng Started web page provides a pre-
built reference image that can be wrien to a microSD card for out-of-the-box funconality.
SOM board support packages (BSPs) are also available if you want to customize your OS.
RECOMMENDED: The SOM is designed to use SDHC standard microSD cards.

Accelerated Applications
The Xilinx SOM plaorms are enabled with a number of accelerated applicaons that can be
dynamically installed on the SOM plaorm. The SOM starter Linux image is applicaon agnosc
and provides a set of ulies for pulling the hardware accelerated applicaon examples from the
SOM Linux package feeds.
Accelerated applicaons are soware controllable, applicaon-specic reference designs for AI
developers, embedded developers, and system architects to customize and enhance the
funconality through soware control or updang the AI models. The following table outlines
some featured accelerated applicaons available for the KV260 Starter Kit. Consider this list as a
starng point because the SOM Geng Started web page contains the most up-to-date
accelerated applicaons availability.
Table 5: KV260 Accelerated Applications
Name Description
Smart camera Configurable camera/sensor input options with hardware accelerated ML
inference with face detection and other models that can be dynamically loaded.
Inference information is outputted to a monitor or network via RTSP.
AI box-ReID Multi-stream IP camera RTSP inputs with hardware accelerated ML inference
models supporting face detection and re-identification (ReID) models. Outputs
are displayed to monitor.
Defect detection Hardware accelerated machine vision application as applied in defect detection.
Accelerated Application Package Selection
RECOMMENDED: Public Ethernet connecvity is necessary to dynamically pull down the latest
accelerated applicaon designs.
1. If you have not already veried Internet connecvity do so before proceeding via ping test or
DNS lookup (e.g., nslookup).
2. The sudo xmutil getpkgs lists a series of package groups that apply to your plaorm.
The package group naming convenon is: packagegroup-kit_name-
application_name. For example, the Smart Camera applicaon for the KV260 plaorm
has the following package group name packagegroup-kv260-smartcamera. You can
install any number of matching accelerated applicaons to your plaorm by execung a DNF
install for the chosen applicaon package group. For example, to install the smart camera
applicaon, run sudo dnf install packagegroup-kv260-smartcamera.
Note: You should only install package-groups that are compable with your parcular starter kit
conguraon.

3. For any applicaons installed on the local le system via the DNF install, the plaorm can
now dynamically load and swap those applicaons. To see a list of the applicaons local to
the system, execute sudo xmutil listapps. You can also see what applicaons are local
by manually exploring the /opt/xilinx directory.
4. By default, kv260-dp is loaded on boot. From the applicaons list, check for an acve
applicaon loaded (acve = 1 in the xmutil listapps output). If there is a loaded
applicaon, unload it by running the sudo xmutil unloadapp command to unload the
current applicaon before proceeding to the next step.
5. From the applicaon list, start the new applicaon by running sudo xmutil loadapp
application_name. The plaorm conguraon is automacally handled and starts the
applicaon.
6. Applicaons with a Jupyter-based cockpit will start-up automacally. You need to point your
web-browser to the associated IP address and port. The associated IP address and port
informaon is printed to the UART at boot. To query your Jupyter lab server URL aer the
inial boot, run: sudo jupyter notebook list.
