ZedBoard Quick start

https://media.githubusercontent.com/media/analogdevicesinc/documentation/main/docs/solutions/reference-designs/ad9467_fmc_250ebz/images/ad9467_zedboard_setup.png

All the products described on this page include ESD (electrostatic discharge) sensitive devices. Electrostatic charges as high as 4000V readily accumulate on the human body or test equipment and can discharge without detection. Although the boards feature ESD protection circuitry, permanent damage may occur on devices subjected to high-energy electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance degradation or loss of functionality. This includes removing static charge on external equipment, cables, or antennas before connecting to the device.

This guide provides quick instructions on how to setup the EVAL-AD9467 on:

Using Linux as software

Necessary files

The following files are needed for the system to boot:

  • HDL boot image: BOOT.BIN

  • Linux Kernel image: uImage

  • Linux device tree: devicetree.dtb

They can either be taken from the SD card – already generated by us, or you can build them manually.

In the following sections, we explain how to take them from the SD card.

Instructions on how to manually build the boot files from source can be found here:

Required Software

  • SD Card 16GB imaged with Kuiper (check out that guide on how to do it, then come back to this section)

  • A UART terminal (Putty/Tera Term/Minicom, etc.) with baud rate 115200 (8N1)

  • Scopy v2.0 or later (must contain the IIO plugin)

Required Hardware

  • AMD Xilinx ZedBoard

  • EVAL-AD9467 FMC evaluation board

  • SD card with at least 16GB of memory

  • Micro-USB cable (UART)

  • LAN cable (Ethernet, optional)

  • (Optional) USB keyboard & mouse and a HDMI compatible monitor

  • Clock source (250 MHz, 16 dBm, 50 Ω)

  • Analog signal source with appropriate filter

More details as to why you need these, can be found at Prerequisites.

Testing

Creating the setup

Follow the steps in this order, to avoid damaging the components:

  1. On the ZedBoard, set the boot mode jumpers to SD card boot

    https://media.githubusercontent.com/media/analogdevicesinc/documentation/main/docs/solutions/reference-designs/images/zed_sw.png https://media.githubusercontent.com/media/analogdevicesinc/documentation/main/docs/solutions/reference-designs/ad9467_fmc_250ebz/images/ad9467_table1.png

  2. Insert the SD Card into ZedBoard SD Card Interface Connector (J12)

  3. Plug the AD9467-FMC-250EBZ to ZedBoard FMC Connector (J1)

  4. On the AD9467-FMC-250EBZ board:

    • Provide a clean, low jitter 250 MHz clock source to connector J201 (set amplitude to 16 dBm)

    • Use SMA male cable for connecting the clock source

    • Provide an analog input signal to connector J100

    https://media.githubusercontent.com/media/analogdevicesinc/documentation/main/docs/solutions/reference-designs/ad9467_fmc_250ebz/images/ad9467_connections.jpg

  5. Connect a Micro-USB cable from your PC to the ZedBoard UART port (J14)

  6. Connect Ethernet cable from your router/switch to the Ethernet port on the FPGA board.

  7. Connect a 12V power supply to ZedBoard barrel jack (J20)

  8. Turn on the power switch on the ZedBoard (SW8) - Green Power LED (LD13) should illuminate - After several seconds, the blue Done LED (LD12) should illuminate

  9. Open a terminal emulator (PuTTY, Tera Term, etc.) with the following settings:

    • Serial line: <ZedBoard COM Port Number>

    • Speed (baud): 115200

    https://media.githubusercontent.com/media/analogdevicesinc/documentation/main/docs/solutions/reference-designs/images/putty_connect.png

Useful commands for the serial terminal

The below commands are to be run in the serial terminal connected to the FPGA.

To find out the IP of the FPGA board, run:

ifconfig

To see the IIO devices detected, run:

iio_info | grep iio:device

iio:device0: xadc
iio:device1: ad9517-4
iio:device2: cf-ad9467-core-lpc (buffer capable)

To power off the system, run:

poweroff

To reboot the system, run:

reboot

Important

Even though this is Linux, it uses a persistent file system. Care should be taken not to corrupt the file system – please shut down properly rather than just turning off the power switch.

About the IIO devices

The AD9467 ADC is handled by the cf-ad9467-core-lpc IIO device.
