General Description
The EVAL-AD2S1210SDZ is a full featured evaluation board designed to allow the user to easily evaluate all the features of the AD2S1210 resolver-to-digital converter (RDC).
Quick Start Guide
Loading Image on SD Card
To boot the Zedboard and control the EVAL-AD2S1210SDZ, you will need to install ADI Kuiper Linux on an SD card. Complete instructions, including where to download the SD card image, how to write it to the SD card, and how to configure the system are provided on the Kuiper Linux page.
Configuring the SD Card
Follow the configuration procedure under Configuring the SD Card for FPGA Projects on the Kuiper Linux page. Copy the following files onto the boot directory to configure the SD card:
- uImage file for Zynq
- BOOT.BIN specific to your EVAL-AD2S1210SDZ + ZedBoard
- devicetree.dtb for Zynq specific to your EVAL-AD2S1210SDZ + ZedBoard
Setting up the Hardware
You will need to:
- Insert the SD-CARD into the SD Card Interface Connector (J12).
- Connect the EVAL-AD2S1210SDZ board to the SDP adaptor and into the ZedBoard FMC connector.
- Connect USB UART J14 (Micro USB) to your host PC.
- Plug your ethernet cable into the RJ45 ethernet connector(J11).
- Plug the Power Supply into the 12V Power input connector (J20) (DO NOT turn the device on).
- Set the jumpers as seen in the below picture:
Before executing the below steps, make sure that VADJ jumper is set to 3.3V.
- Connect the oscilloscope probes to the SMB connectors.
- Turn it on.
- Wait ~30 seconds for the “DONE” LED to turn blue. This is near the DISP1.
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.
