Firmware Update; Ethernet Recovery Tool - Xilinx Kria KV260 User Manual

Firmware Update

The firmware update button is the physical SW1/FWUEN push button located on the KV260
Starter Kit carrier card. The button is used to support two features:
1. To force the platform into a recovery mode application during power-on. The recovery
application is described in the
2. Security mechanism to prevent remote update of the boot firmware, without the user being
physically present.

Ethernet Recovery Tool

The Ethernet recovery tool is a small application included in the Xilinx provided KV260 Starter
Kit QSPI image. It provides a simple Ethernet-based interface and application for updating the
boot firmware. This application and interface is initiated by holding the firmware update button
during the power-on sequence. The application uses a fixed IP address of 192.168.0.111. The
following figure shows an overview of the set-up.

Computer
The Ethernet recovery tool provides a mechanism for updating either of the dynamic boot
partitions within the primary boot device if Linux is not functional. If Linux is functional, the
recommendation is to update the boot firmware using the xmutil boot firmware update
utilities. The associated update content is a Xilinx XCK26 binary boot image captured as
BOOT.BIN. To support platform recovery, the KV260 Starter Kit factory BOOT.BIN image is
made available on the Xilinx SOM Getting Started web page. You can also use this tool when
customizing the platforms boot firmware with your own BOOT.BIN generated through the Xilinx
Vitis and PetaLinux tools.
To use the Ethernet recovery tool, follow these steps:
