ZedBoard Quick start

This guide provides quick instructions on how to set up the EVAL-AD9434 on:

ZedBoard

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

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:

Build Zynq Linux kernel and devicetree
AD9434-FMC HDL project build documentation. More HDL build details at Build an HDL project.

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)

Required Hardware

AMD Xilinx ZedBoard FPGA board and its power supply (12V)
EVAL-AD9434 FMC evaluation board
SD card with at least 16GB of memory
Mini-USB cable (UART)
LAN cable (Ethernet)
SMA cables
- 1x for the input, in case of not using an external clock source (see User guide)
- 2x in case of using and external clock source, one for CLKIN input port and one for AIN input port (see User guide)
(Optional) USB keyboard & mouse and a HDMI compatible monitor

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

Testing

Creating the setup

https://media.githubusercontent.com/media/analogdevicesinc/documentation/main/docs/solutions/reference-designs/eval-ad9434-fmc/images/ad9434_zed_os_setup.png

In the following example, we will make a physical connection between the ADC and an external signal generator, using SMA cables.

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

Get the ZedBoard
Configure ZedBoard for SD BOOT:

The BOOT switches (JP7-JP11) and the MIO0 jumper (JP6) must be set for SD-card boot mode. VADJ must be set to 3.3V, as specified in the HDL project’s README at AD9434-FMC HDL project. Optionally, to use USB peripheral devices with the ZedBoard, install jumpers JP2 and JP3.
Plug the Power Supply into 12V Power input connector (J20) (DO NOT turn the device on)
Insert the SD card into the SD Card Interface Connector (J12)
Connect your signal generator to the analog inputs of the evaluation board using the appropriate jumper wires or SMB connectors.
Connect the EVAL-AD9434 FMC board to the ZedBoard FMC LPC Connector (J1)
Plug-in an Ethernet cable from your router/switch to the Ethernet port on the FPGA board
Connect the UART port of ZedBoard (J14) to a PC via MicroUSB
Turn on the power switch on the FPGA board
Observe Kernel and serial console output messages on your terminal

Boot messages

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

Debian GNU/Linux 13 analog ttyPS0

analog login: root (automatic login)

Linux analog 6.12.0-g298669e57d37 #1 SMP PREEMPT Fri Mar 13 08:38:12 UTC 2026 armv7l

The programs included with the Debian GNU/Linux system are free software;
the exact distribution terms for each program are described in the
individual files in /usr/share/doc/*/copyright.

Debian GNU/Linux comes with ABSOLUTELY NO WARRANTY, to the extent
permitted by applicable law.

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-ad9434-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

Even thought this is Linux, this is a persistent file systems. 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

The IIO Oscilloscope is a cross-platform application for interfacing with IIO devices, enabling you to configure device parameters and visualize data.

Once done with the installation or an update of the latest IIO Oscilloscope, open the application. The user needs to supply a URI which will be used in the context creation of the IIO Oscilloscope.
Press Refresh to display available IIO Devices and press Connect.
After the board is connected and a channel is enabled, hit the play button. Then the data capture window can be seen like in the shown picture.
