ZC706 Quickstart

This guide provides quick instructions on how to set up the EVAL-AD9265 on:

ZC706 (rev 1.1 or higher) FMC LPC

https://media.githubusercontent.com/media/analogdevicesinc/documentation/main/docs/solutions/reference-designs/images/zc706.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.

Using Linux as software

Necessary files

Note

The SD card includes several folders in the root directory of the BOOT partition. In order to configure the SD card to work with a specific FPGA board and ADI hardware, several files must be copied onto the root directory. Using the host PC, drag and drop the required files onto the BOOT partition, and use the EJECT function when removing the SD card from the reader.

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:

Instructions on how to choose the boot files from the SD card can be found in the Platform-Specific Manual Steps section from here: Hardware Configuration.
Instructions on how to manually build the boot files from source can be found here:
- Build Zynq Linux kernel and devicetree
- AD9265-FMC HDL project build documentation. More HDL build details at Build an HDL project.

Important

Some projects provide multiple devicetree files in the SD card’s boot folders. Make sure you select the devicetree that matches your specific use case.

Required software

SD card (16 GB minimum) imaged with Kuiper (see that guide for instructions, then return here)
IIO Oscilloscope
A UART terminal (PuTTY/Tera Term/Minicom, etc.), baud rate 115200 (8N1)

Required hardware

AMD Xilinx ZC706 Rev 1.1 or higher FPGA board and its 12 V power supply
EVAL-AD9265 FMC evaluation board (AD9265-FMC-125EBZ)
Mini-USB cable (UART, connects to J21)
LAN cable (Ethernet, connects to J45)
Signal generator (low-jitter, low-phase-noise recommended)
SMA cables for analog input connection to J100

More details can be found at Prerequisites.

Testing

Creating the setup

Caution

This project was tested with VADJ = 2.5 V

https://media.githubusercontent.com/media/analogdevicesinc/documentation/main/docs/solutions/reference-designs/eval-ad9265/images/ad9265_setup_zc706.jpg

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

Get the ZC706
Insert the SD card into the SD Card Interface Connector (J30)
Plug the EVAL-AD9265 into the FMC LPC Connector (J5)
Connect your signal generator to the analog input of the evaluation board using a SMA cable connected to the J100 pin.
Plug the Mini-USB cable into the UART connector (J21) and connect it to your host PC.
Plug the Ethernet cable into the Ethernet connector (J45) and connect it to your host PC.
Plug the Power Supply into 12V Power input connector (J22) (DO NOT turn the device on).
Set the boot mode switch (SW11). For SD card boot, set it to: 1: Down, 2: Down, 3: Up, 4: Up, 5: Down.
Turn on the power switch on the FPGA board
Connect to the serial console to observe the boot messages

Boot messages

The following is what is printed in the serial console, after you have connected to the proper ttyUSB or COM port:

Linux analog 5.10.0-98744-g64e7a607b659 #1788 SMP PREEMPT Fri Mar 31 16:51:05 EEST 2023 armv7l

The programs included with the Debian GNU/Linux system are free software;
the exact distribution terms for each program are described in the

Useful commands for the serial terminal

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

Login Information

user: analog password: analog

To find out the IP of the FPGA board, run the following command and take the IP specified at “eth0 inet”:

~$

ifconfig

To see the IIO devices detected, run:

~$

iio_info | grep iio:device

iio:device0: xadc
iio:device1: ad9517-4
iio:device2: axi-ad9265-core-lpc (buffer capable)

To power off the system, run the following command, and wait for the final message to be printed, then power off the FPGA board from the switch as well.

~$

poweroff

To reboot the system, run:

~$

reboot

Important

This is a persistent file system. Care should be taken not to corrupt the file system - please shut down things, don’t just turn off the power switch. Depending on your monitor, the standard power off could be hiding. You can do this from the terminal as well with sudo shutdown -h now or the above-mentioned command for powering off.

IIO Oscilloscope

Important

Make sure to download/update to the latest version of IIO Oscilloscope.

Once the board has booted, open IIO Oscilloscope on your host PC. Supply the board’s IP address as the URI in the format ip:<ip_address>. To find the IP address, run ifconfig in the serial terminal and look for the address under eth0 inet.
Press Refresh to display available IIO devices and press Connect after your device has been detected.
Select the axi-ad9265-core-lpc device and enable the voltage0 channel. Press the Play button to start sampling. The data capture window will show the digitized waveform from the ADC in both time and frequency domains.

Using no-OS as software

Necessary files

The following files are needed to build and run the no-OS project:

HDL hardware description: system_top.xsa — generated from the HDL project
no-OS project: projects/ad9265-fmc-125ebz

Instructions on how to build these from source can be found here:

AD9265-FMC-125EBZ no-OS Example Project. More no-OS build details at No-OS Build Guide.
AD9265-FMC HDL project. More HDL build details at Build an HDL project.

Required software

AMD Xilinx Vitis 2025.1 or later (includes Vivado; download from here)
Python 3, CMake, and Ninja (required by the no_os_build.py build script)
A UART terminal (PuTTY/Tera Term/Minicom, etc.), baud rate 115200 (8N1)

Required hardware

AMD Xilinx ZC706 Rev 1.1 or higher FPGA board and its 12 V power supply
EVAL-AD9265 FMC evaluation board (AD9265-FMC-125EBZ)
Mini-USB cable (UART, connects to J21)
Micro-USB cable (JTAG)
Signal generator (low-jitter, low-phase-noise recommended)
SMA cables for analog input connection to J100

More details can be found at Prerequisites.

Hardware setup

https://media.githubusercontent.com/media/analogdevicesinc/documentation/main/docs/solutions/reference-designs/eval-ad9265/images/ad9265_jtag_setup.jpg

Caution

This project was tested with VADJ = 2.5 V

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

Connect the EVAL-AD9265 FMC board to the ZC706 LPC FMC socket (J5)
Connect your signal generator to the analog input SMA connector (J100) on the evaluation board.
Configure the ZC706 for JTAG boot mode by setting SW11:

Connect the Mini-USB cable to the UART connector (J21) and to your host PC
Connect the Micro-USB cable to the JTAG connector and to your host PC
Connect the power supply to the 12 V Power Input Connector (J22)
Turn on the power switch (SW1) on the FPGA board — the green LED (DS22) will illuminate when power is on

Supported examples

Demo example

The demo example initializes the AD9265 ADC via the AXI ADC core and AXI DMAC, runs test pattern verification on the digital output lanes, and performs a DMA capture of ADC samples into DDR memory.

Build and flash

~$

source /opt/Xilinx/2025.1/Vitis/settings64.sh

~$

cd no-OS

~/no-OS$

python tools/scripts/no_os_build.py build \
  --project ad9265-fmc-125ebz --variant demo --board zc706 \
  --hardware /path/to/system_top.xsa \
  --probe openocd --flash

Boot messages

The following is what is printed in the serial console after the demo example boots:

Demo boot log

ad9265_core: Successfully initialized (125001525 Hz)
ooooooo|ooooooo------------------
DCO 0x6
AD9265 successfully initialized.
Capture done.
Done

IIO example

The IIO example launches an IIOD server on the carrier board so that the user may connect to it via an IIO client. Using the IIO Oscilloscope application, users can configure the AD9265 ADC and visualize captured data from the 16-bit, 125 MSPS ADC.

Build and flash

~$

source /opt/Xilinx/2025.1/Vitis/settings64.sh

~$

cd no-OS
