3.1. Default Settings

The Agilex™ 7 FPGA M-Series HBM2e 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 factory default switch settings table to return to its factory settings before proceeding ahead.

Table 4.  Factory Default Switch Settings
Note: X refers to Don't Care in the table below.
Note: Do not set the switches when the power is on. Only set the switches after the power is off.
Switch Default Position Notes
S24[1:4] OFF/OFF/OFF/ON S24[1:3]
Set MSEL mode:
  • 111: JTAG
  • 011: Avalon® streaming interface x8 configuration mode
S24[4]:
  • OFF–FPGA can access three QSFPDD modules
  • ON–system_info_0_slv_data_write_0[2] determines if FPGA can access three QSFPDD modules or not. No access by default.
S25 OFF
  • OFF–HPS is not in the JTAG chain
  • ON–HPS is in the JTAG chain
S3 OFF
  • OFF–FMC+ is not in the JTAG chain
  • ON–FMC+ is in the JTAG chain
S26 ON
  • ON– MAX® 10 programming via on-board Intel® FPGA Download Cable
  • OFF– MAX® 10 programming via external Intel® FPGA Download Cable
OFF Using mini USB JTAG
S28[1:4] OFF/ON/OFF/OFF

S28[1:2]

Select the clock source for EU122:
  • ON:ON–disabled
  • OFF:ON–internal crystal (default)
  • ON:OFF–CLKIN2 (MCIO)
  • OFF:OFF–CLKIN3 (SMP)

S28[3:4]

Set SSC:
  • ON:X–disabled (default)
  • OFF:X–AND OUT0
  • X:ON–disabled (default)
  • X:OFF–enable SS on N1 divider OUT6, OUT7
SW6 OFF MAX® 10 JTAG Enable switch when the JTAG pin sharing is enabled:
  • ON–JTAG pins function as dual-purpose pins
  • OFF–JTAG pins function as JTAG dedicated pins

This switch can be set to either ON or OFF with the current MAX® 10 design because the JTAG pin sharing is not enabled in the design.

S4 ON Select configuration image in the dual-configuration images mode:
  • ON–the first configuration image is configuration image 0
  • OFF–the first configuration image is configuration image 1

This switch can be set to either ON or OFF with the current MAX® 10 design because single image mode is used in the design.

S16 [1]/[0] Controls the configuration for the U35 clock device
OFF/OFF (default) Input clock from XTAL
OFF/ON Input clock from SI5391
ON/OFF Input clock from FPGA
ON/ON Not connected
SW20 [1]/[0] Controls the configuration for the U93 clock device
OFF/OFF(default) Input clock from XTAL
OFF/ON Input clock from SI5391
ON/OFF Input from FPGA
ON/ON Not connected
