3. Setting Up the Demo
3.1. Hardware Setup
This section covers the steps in programming the demo to the SPI memory of the Certus-NX Versa Evaluation Board.
To program the demo to the SPI memory:
1. Install the jumpers listed in Table 3.1 . Note the difference between J and JP jumpers. If this is your first time
utilizing the Certus-NX Versa Evaluation Board, the jumpers are already in this configuration.
Table 3.1. List of Jumpers to be Set for Programming
Jumper Checklist Notes: Pin 1 is denoted with a small triangle.

2. Connect the 12 V power adapter to J11.The power LED D1, D2, D3, D4, D5, D6, D7, D8, D8, D9, D10, D11, D12, D13,
D14, D15, D16 D17 glow.
3. Connect the USB cable to the computer and to J2. D26 glows. D26 is located closest to the micro USB slot on the
Certus-NX Versa Evaluation Board.
4. At this point, the board is prepared to receive a bit stream from Radiant Programmer. Once the demo bit stream is
written to the board, you can move the board into the PCIe X1 slot in the host machine.
3.1.1. Installing Hardware into a Different Slot
Windows identifies PCI/PCI Express hardware devices using the bus, slot, vendor ID, and device ID fields. If you install
the board into a different slot, the slot number changes. This causes Windows to display the Found New Hardware
screen when the system powers up.
Moving the Certus-NX Versa Evaluation Board into a different slot while the machine is powered on causes the demo to
fail. You will not be able to run memory access tests nor control the seven segment display.
To restart the demo, ensure that the board is in the desired PCIe slot and restart the host machine. When the board is
set up and hardware is installed on your computer, you can perform software installation, execution, and other tasks to
complete the demo.
