3.2.1. Restoring the Default Settings for Power Solution 2 Board

Figure 5. Switch Locations and Default Settings for Power Solution 2 Board

To restore Cyclone® V SoC Development Kit (Power Solution 2) board switches to their factory default settings, perform these steps:

  1. Set the DIP switch bank (SW2) to match the SW2 DIP Switch Settings table.

    In the following table, ON indicates the switch is to the left according to the board orientation as shown in the Switch Locations and Default Settings for Power Solution 2 figure.

    Table 3.  SW2 DIP Switch Settings
    Switch Board Label Function Default Position
    1 CLK125A Switch 1 has the following options:
    • ON (0)—Onboard oscillator is disabled.
    • OFF (1)—Onboard oscillator is enabled.
    OFF
    2 Si570 Switch 2 has the following options:
    • ON (0)—Onboard programmable oscillator is enabled.
    • OFF (1)—Onboard programmable oscillator is disabled.
    ON
    3 FACT LOAD Switch 4 has the following options:
    • ON (0)—Load the factory design starting at 0x20000 at power up.
    • OFF (1)—Parallel flash loader (PFL) disabled.
    OFF
    4 Security Switch 4 has the following options:
    • ON (0)—Onboard Intel® FPGA Download Cable II sends FACTORY command at power up.
    • OFF (1)—Onboard Intel® FPGA Download Cable II does not send FACTORY command at power up.
    OFF
  2. Set the DIP switch bank (SW3) to match the SW3 DIP Switch Settings table.

    In the following table, up and down indicates the position of the switch with the board orientation as shown in the Switch Locations and Default Settings for Power Solution 2 figure.

    Important: The default MSEL pin settings are set to all zeroes (ON) to select the fast passive parallel x16 mode. For power-up configuration from MAX V and CFI flash, ensure that the MAX® V design uses this same mode as does in the design in the cycloneVSX_5csxfc6df31_soc\examples\max5 directory.

    • ON (up)—MSEL4 is 0.
    • OFF (down)—MSEL4 is 1.
    ON
  3. Set the DIP switch bank (SW4) to match the SW4 JTAG DIP Switch Settings table.

    In the following table, up and down indicates the position of the switch with the board orientation as shown in the Switch Locations and Default Settings for Power Solution 2 figure.
