ZedBoard quick start
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.
Required software
A UART terminal (PuTTY / Tera Term / Minicom) at 115200 baud, 8N1
libiio installed on the host PC
IIO Oscilloscope and/or Scopy installed on the host PC
Required hardware
ZedBoard Rev D or later
EVAL-AD3552RFMCxZ evaluation board
16 GB (or larger) Class 10 micro-SD card
12 V, 3 A power supply
Micro-USB cable (UART)
Ethernet cable
Setting up the SD card
Download and install the ADI Kuiper Linux image by following the Using Kuiper Images instructions.
Copy the boot files (
BOOT.BIN,uImage,devicetree.dtb) from the ADI Kuiper Linux image to the FAT boot partition of the SD card.To build the HDL bitstream and software from source, follow these steps.
HDL reference design
Clone the HDL repository and build the ZedBoard project:
~$
cd hdl/projects/ad3552r_fmcz/zed
~/hdl/projects/ad3552r_fmcz/zed$
make
The bitstream is written into
hdl/projects/ad3552r_fmcz/zed/ad3552r_fmcz_zed.sdk/.Kuiper Linux kernel and device tree
Refer to Using Kuiper Images for building
uImageanddevicetree.dtbfor Zynq with the AD3552R device tree overlay.
Setting up the hardware
Insert the prepared micro-SD card into the SD card slot (J12) on the ZedBoard.
Configure the boot mode and VADJ voltage. The ZedBoard jumpers should be set for SD card boot and VADJ = 1.8 V.
Important
Set VADJ to 1.8 V before powering on. The AD3552R uses 1.8 V signaling on the FMC connector; a higher VADJ voltage can damage the evaluation board.
With the ZedBoard powered off, insert the EVAL-AD3552R evaluation board into the FMC LPC connector.
Connect the Micro-USB cable from J14 (USB UART) to your host PC.
Connect the Ethernet cable to J11 (RJ-45).
Connect SMB probes to J4 (CH0 output) and J5 (CH1 output) on the evaluation board to monitor the DAC outputs.
Connect the 12 V power supply to J20 and power on the ZedBoard.
Wait approximately 30 seconds for the DONE LED near DISP1 to turn blue, indicating the bitstream has been loaded.
Booting
Open the UART terminal (115200 baud, 8N1) on the host PC and observe the
boot log. The system auto-logs in as root.

Useful commands
Check network address:
~$
ifconfig eth0
List IIO devices:
~$
iio_info | grep iio:device
Power down the board safely:
~$
poweroff
Using IIO Oscilloscope
Install the latest IIO Oscilloscope on the host PC.
Open IIO Oscilloscope. In the connection dialog, enter the URI of the ZedBoard:
ip:<ip-address-of-zedboard>
For local access directly on the ZedBoard, use:
ip:localhost
Note
The host PC and ZedBoard must be on the same network for IP-based access. You can verify connectivity with
iio_info -u ip:<ip-address-of-zedboard>from the host PC.Click Refresh to populate the device list, then click Connect.
In the DAC plugin, select the
axi-ad3552rdevice. You can set raw output codes for each channel or configure DDS tone generation.
Use the Debug tab to access individual IIO attributes directly, such as
output_range,sampling_frequency, andout_voltage0_raw.
Note
If the sine wave on the oscilloscope looks split, this is a data format mismatch. The AXI IP core defaults to offset binary, but if your software sends two’s complement samples (or vice versa), the output wraps around like this.
To fix it, run on the ZedBoard:
busybox devmem 0x44A70048 32 0x4030
This sets the DATA_FORMAT bit in the DAC interface control
register to offset binary (1). Set it to 0 for two’s
complement.
Using Scopy
Install Scopy on the host PC.
Connect to the ZedBoard using the network URI
ip:<ip-address-of-zedboard>.Open the IIO plugin in Scopy to read and write IIO device attributes, or use the Signal Generator plugin to stream samples to the DAC.
Using PyADI-IIO
Install PyADI-IIO on the host PC, then run the example script:
export PYTHONPATH=/path/to/pyadi-iio/
python examples/ad3552r_hs_example.py ip:<ip-address-of-zedboard>
The script generates an 80 kHz sine wave in offset-binary uint16 format and streams it to both DAC channels in cyclic mode. Expected output:
uri: ip:<ip-address-of-zedboard>
sample rate: 33333333
Sample data min: 1
Sample data max: 65534
A matplotlib window will appear showing the generated waveform. The DAC outputs on J4 and J5 should show a clean 80 kHz sine wave.
Using No-OS
The No-OS ad3552r_fmcz project runs on the Zynq PS ARM core and
exposes an IIOD server over UART. To use it:
The hardware setup is the same as for the Linux instructions above. You need an extra micro USB cable to connect the ZedBoard’s JTAG port to the host PC in order to flash the No-OS firmware.
Program the ZedBoard with the No-OS firmware (built from projects/ad3552r_fmcz).
Observe the boot output on the UART terminal:
Hey, welcome to ad3552r_fmcz AXI example tx_clkgen: MMCM-PLL locked (133000000 Hz) ad3552r_core: Successfully initialized (133332824 Hz) Running IIOD server... If successful, you may connect an IIO client application by: 1. Disconnecting the serial terminal you use to view this message. 2. Connecting the IIO client application using the serial backend: Baudrate: 115200 Data size: 8 bits Parity: none Stop bits: 1 Flow control: noneClose the serial terminal, then connect IIO Oscilloscope using the serial backend.
