ZedBoard Quick start
This guide provides some quick instructions on how to setup and test the HMCAD1511-EBZ/HMCAD1520-EBZ on:
ZedBoard FMC (J1) port
Using Linux as software
Necessary files
The following files are needed for the system to boot:
HDL boot image:
BOOT.BINLinux Kernel image:
uImageLinux device tree:
devicetree.dtb
Instructions on how to manually build the boot files from source can be found here:
HMCAD1520-FMC-EVB HDL project build documentation. More HDL build details at Build an HDL project.
Required Software
Scopy v2.2 or later (must contain the ADC Plugin)
An UART terminal (Putty/Tera Term, etc.) with baud rate 115200 (8N1)
Required Hardware
AMD Xilinx ZedBoard
12V 1A barrel jack supply for ZedBoard
HMCAD1520-EBZ/HMCAD1511-EBZ FMC board
Micro-USB cable
LAN Cable (Ethernet)
Signal Generator
SMA male to BNC male cable
External 1GHz clock source if working with the HMCAD1520-EBZ + extra SMA male to SMA male cable, because it does not include an on-board crystal like the HMCAD1511.
An SD card with at least 16GB of memory.
(Optional) USB keyboard & mouse and a HDMI compatible monitor
Testing
Creating the setup
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.
Follow the steps in this order, to avoid damaging the components:
Connect the HMCAD1520-EBZ/HMCAD1511-EBZ FMC board to the FPGA carrier FMC socket
Connect USB UART J14 (Micro-USB) to your host PC
Insert SD card with ADI Kuiper image into socket J12
Set VADJ Select Jumper J18 to 2V5.
Configure Jumpers for SD Card boot mode (JP7-JP11 and MIO0)
Connect an Ethernet cable to Ethernet port J11
Setup the signal generator. In this guide we used a sinusoidal signal with an amplitude of 1V and a frequency of 200kHz.
Connect the signal generator output to the IP4 port on the evaluation board (J7)
If you work with the HMCAD1520-EBZ you will need to connect it to an external clock source since it doesn’t include an on-board crystal. Connect the external clock source to the J1 SMA port on the evaluation board. Optionally you can bypass the need of an external clock by soldering a 1GHz crystal at Y1 and moving the resistance from R12 to R13.
Make sure the clock source is set to 1 GHz and 10 dBm and start it
Connect via UART with the terminal of your choice - For Putty :
Select Serial
Insert baud rate of 115200
- Insert the COM port the ZedBoard is connected to
In order to find the COM port: Device Manager -> Ports(COM & LPT)
Turn on the power switch on the FPGA board

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:
root@analog:~# iio_info | grep iio:device
iio:device1: xadc
iio:device2: axi_adc_hmcad15xx (buffer capable)
~$
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.
