3.2. Default Switch and Jumper Settings
This section guides you how to restore the default factory settings and provides their
functions.
3.2.1. Default Setting
The Intel Agilex I-Series FPGA Development Kit ships with its board switches
preconfigured to support the design examples in the kit. If you suspect your board
might not be correctly configured with the default settings, follow the instructions in
on page 11 to return to its factory settings before proceeding.
