NOTE: Once the image is programmed eject the SD Card and re-insert it. The SD card will already include a few folders in its BOOT partition. Those can be ignored for this setup.

  • For the SD card to boot correctly place the socfpga_stratix10_socdk.dtb and the u-boot.itb files provided in the SD card folder into the top-level directory (BOOT D:). In addition to this, also place one of the Image files either from the Dual 10G Image [for Synchronized 10G Mode] folder or the Single 20G Image [for Interleaved 20G Mode] folder into the top-level directory based on use case
  • Replace the SD Card on the Stratix10 SX SoC Board with the SD Card you just programmed.
  • Power up the boards and configure the signal generators as in the Signal Generators section above.
    • a. Start with low test signal power (about 0dBm). This can be adjusted later as desired.
    • b. For the reference clock signal set the generator power to 5dBm.
  • Setup the COM port connection to your PC
    • a. Determine the USB-COM port connection to your PC by looking in the device manager under Ports (COM & LPT).

Figure 2. Setting up the COM port connection from the Stratix10 SX SoC board to the PC


    • b. Once you determine the COM port connection, right click to open properties, and navigate to the Port Settings tab. In that tab change the Bits per second value to 115200. Click Ok to apply the new settings.


Figure 3. Configuring the COM port settings

NOTE: This procedure needs to be performed every time the Stratix 10 board’s USB to mini-USB COM connection cable is physically disconnected and re-connected to the PC.

  • Run PuTTY to establish communications
  • In the PuTTY Options page, specify:
    • a. Serial as the Connection Type
    • b. The COM port as determined (in the section above) as the serial line Note: The COM port number will depend on port availability on the user’s machine.
    • c. 115200 as the Speed
    • d. Save this configuration for quicker setup next power cycle


Figure 4. Opening the COM port connection using PuTTY

  • Program the Board using the Quartus Prime Programmer 19.3:
    • a. Start Quartus Prime Programmer 19.3
    • b. The software should be able to detect the Stratix10H SoC Evaluation Board automatically and it will show up in the Hardware Setup section on the top. If it does not show up automatically try to select it manually.
    • c. Once you see the board has been detected, click on 'Add File'.


Figure 5. Setting up the Quartus Programmer to program the FPGA Image


    • d. Navigate to the location of the FPGA program (ADI provided) and select the file. (ad9213_dual_ebz_s10soc_hps_20_4.sof), and click 'Open'.

NOTE: It will take a few seconds for the file to add and the FPGA device to show up on the screen.

    • e. Click 'Start'.
    • f. Wait for the programmer to complete.

NOTE: The FPGA being programmed also triggers the Linux boot on the HPS. The PuTTY COM console provides updates on the progress of the boot.

  • The PuTTY COMx console will display a verbose running of the initialization scripts at the end of which the setup will be ready


Figure 7. COM console once the boot process and initialization are complete


  • The IP address of the board can be obtained by running the ifconfig command in the console


Figure 8. Using ifconfig to obtain the IP address of the Stratix10 SX SoC board ethernet connection


  • Open PuTTY again to establish an SSH connection to the board. This connection allows you to control components on the board via SPI.

NOTE: This step is only needed if you need to perform SPI writes or reads to the board components using scripts when using Interleaved 20G Mode

  • In the PuTTY Options page, specify:
    • i. SSH as the Connection Type
    • ii. IP address of the Stratix10 board, obtained in the previous step.
    • iii. Port number 22
    • iv. Save this configuration for quicker setup next time

    • b. Once you click refresh all the IIO Devices on the Dual-9213 evaluation board including the two AD9213s and the other clock chips will show up. Click Connect.


Figure 12. All devices on evaluation board ready to connect to IIO Scope


NOTE: These two steps only need to be done when using IIO Scope with a setup for the first time. The next time you open IIO Scope and are using the same setup it will auto-detect the setup and open the configuration and plotting windows.

    • c. After you connect a SPI Controller window and a Plotting window will open.
    • d. Use the SPI controller window to select a device you'd like to communicate with and then use the register section at the bottom to read or write individual registers.

NOTE: This only needs to be used if you are looking to do reads and writes in addition to the automatic startup configuration that has already been run.

Figure 13. Using the IIO Scope Controller View to Read and Write SPI


    • e. Use the plotting window to capture data from one AD9213 at a time or from both simultaneously. The selection of the AD9213 and the number of samples can be made using the panels on the left. The tool allows both time domain and frequency domain captures.


NOTE: If the SD card image used is for the Interleaved 20G Mode, voltage 0 (channel 0) will represent data from both ad9213_0 and ad9213_1 as a combined waveform or a combined FFT

Figure 14. Using the IIO Scope Plotting View to plot separate time domain outputs from each AD9213 (Ain = 136 MHz @5dBm)


NOTE: Frequency domain plotting with more detailed analysis can be performed using a Visual Analog Canvas, the following are the steps to use VA

  • One-Time IIO Installations Before Running VisualAnalog (only needed if VisualAnalog Canvas provided by ADI will be used)
