f For more information on the MSEL modes, refer to Configuration, Design

Security, and Remote System Upgrades in Cyclone V Devices.

4. Set the J17 jumper block to match Table 4–4 and Figure 4–2. 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

Table 4–4 and Figure 4–2.

f For more information about the FPGA board settings, refer to the Cyclone V GT FPGA

Development Board Reference Manual.

Restoring the MAX V CPLD to the Factory Settings

This section describes how to restore the original factory contents to the MAX V

CPLD on the FPGA development board. Make sure you have the Nios II EDS

installed, and do the following:

1. Set the board switches to the factory default settings described in “Factory Default

Switch and Jumper Settings” on page 4–2.

2. Start the Quartus II Programmer.

3. Click Auto Detect.

4. Click Add File for the 5M2210 MAX V device and select <install

dir>\kits\cycloneVGT_5cgtfd9ef35_fpga\factory_recovery\max5.pof.

5. Turn on the Program/Configure option for the added file.

6. Click Start to download the selected configuration file to the MAX V CPLD.

Configuration is complete when the progress bar reaches 100%.
