4.2. Factory Default Switch and Jumper Settings
The following figure shows the default switch settings for the top side of the Cyclone® V GT FPGA development board.
The following figure shows the default switch and jumper settings for the bottom side of the Cyclone® V GT FPGA development board.
To restore the switches to the default settings, perform the following:
- Set the DIP switch bank (SW3) to match SW3 DIP Switch Settings table and Default Switch Settings on the Board Top figure.
Table 3. SW3 DIP Switch Settings Switch Board Label Function Default Position 1 PCIe_X1 Switch1 has the following options:
- ON (logical 0) = x1 presence detect is enabled.
- OFF (logical 1) = x1 presence detect is disabled.
ON 2 PCIe_X4 Switch2 has the following options: - ON (logical 0) = x4 presence detect is enabled.
- OFF (logical 1) = x4 presence detect is disabled.
ON 3 HSMB_EN Switch 3 has the following options:
ON (logical 0) = HCMC Port B not in JTAG chain.
OFF (logical 1) = Include HCMC Port B in the JTAG chain.
ON 4 HSMA_EN Switch 4 has the following options:
ON (logical 0) = HCMC Port A not in JTAG chain.
OFF (logical 1) = Include HCMC Port A in the JTAG chain.
ON - Set the DIP switch bank (SW4) to match SW4 DIP Switch Settings table and Default Switch Settings on the Board Top figure.
Table 4. SW4 DIP Switch Settings Switch Board Label Function Default Position 1 CLKSEL Switch 1 has the following options:
- ON (logical 0) = SMA input clock select.
- OFF (logical 1) = Programmable oscillator clock select.
OFF 2 CLKEN — ON 3 FACT Switch 3 has the following options:
- ON (logical 0) = Load the factory design from flash at power up.
- OFF (logical 1) = Load the user design from flash at power up.
ON 4 MODE Switch 4 is an optional user switch setting. It is not currently defined in the MAX® V system controller. ON - Set the DIP switch bank (SW5) to match SW5 DIP Switch Settings table and Default Switch Settings on the Board Bottom figure.
Table 5. SW5 DIP Switch Settings Switch Board Label Function Default Position 1 MSEL1 Switch 1 has the following options:
- When ON, a logic 0 is selected.
- When OFF, a logic 1 is selected.
ON 2 MSEL2 Switch 2 has the following options:
- When ON, a logic 0 is selected.
- When OFF, a logic 1 is selected.
OFF 3 MSEL4 Switch 3 has the following options:
- When ON, a logic 0 is selected.
- When OFF, a logic 1 is selected.
OFF 4 FAN Switch 4 has is an optional user switch setting. It is not currently defined in the MAX® V system controller. OFF For more information on the MSEL modes, refer to Cyclone® V Device Handbook: Volume 1: Device Interfaces and Integration.
- Set the J17 jumper block to match J17 Jumper Block table and Default Switch Settings on the Board Bottom figure. The C5_VCCIO_VAR power rail provides the voltage to bank 7, which connects to the HSMB interface. By default this rail is 2.5 V. If needed, you can change the voltage level of this power supply by adding in a jumper wire between the pins of J17 as indicated in J17 Jumper Block table and Default Switch Settings on the Board Bottom figure.
Table 6. J17 Jumper Block Note: Adding a single jumper between the pins sets the voltage as described in the table. Install only one jumper location at a time.Jumper C5_VCCIO_VAR Default Position Pins 1-2 1.8 V Not installed Pins 3-4 1.5 V Not installed Pins 5-6 1.2 V Not installed
