3.2.1. Default Settings
The Agilex™ 7 FPGA I-Series 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 the tables below to return to the factory settings before proceeding.
Switch | Default Position | Function | |||||||||||||||
---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
SW1[1:4] | ON/OFF/OFF/OFF | PCIe* PRSNT x1/x4/x8/x16 settings. Default = x16.

SW2[1:4] | ON/OFF/OFF/X | Configuration mode setting bits.

SW5[1:4] | OFF/OFF/OFF/X | On-board Intel® FPGA Download Cable II is the JTAG host when the external JTAG header (J10) is unoccupied.
|
|||||||||||||||
SW6 | ON/OFF | When the board is not in a PCIe* slot, it must be powered by an external power supply. The SW6 switch turns on the power of the board when it is at the ON position and turns off the power when it is at the OFF position. When the board is in a PCIe* slot, the external and auxiliary power supplies must still be connected. The SW6 switch can be left at either the ON or OFF position. The board can only be powered on when both power sources are present. |
