Board Reset, Firmware Update, and
Recovery
This section outlines the update and recovery mechanisms built into the KV260 Starter Kit. Two
tools are provided for firmware updates. The first is a Linux based A/B update tool that supports
remote and redundant firmware updates to the A/B firmware partitions of the QSPI device with
custom or Xilinx provided updates. The second tool is the Ethernet recovery tool that is intended
to be used only when recovering a full platform to the original factory firmware.
