 Start IMPACT, and double click "Boundary Scan". Right click and select Initialize Chain. The program should recognize the Spartan 6 device (see screenshot below). Start a UART terminal (set the appropiate baud rate) and then program the device using the bit file provided in the project *.zip archive, located in the "sw" folder (../ad5160/sw/AD5160.bit).

+Run the **download.bat** script from the "../bin" folder downloaded from the github (see the links in the download section of the wiki page).
+The script will automatically configure the ZYNQ SoC and download the *.elf file afterwards.

+====== Linux Device Driver ======
+Connect PmodDPOT to the JB1 connector of the ZedBoard (upper row of pins).
+===== Preparing the SD Card =====
+In order to prepare the SD Card for booting Linux on the ZedBoard:
+    * Download the device tree: [[https://github.com/analogdevicesinc/no-OS/tree/master/Pmods/PmodDPOT/dts|PmodDPOT Linux devicetree]]
+    * Follow the instructions on the following wiki page, but use the device tree downloaded on the previous step
+        * [[/resources/tools-software/linux-drivers/platforms/zynq?s=adv7511&s=linux|Linux with HDMI video output on the ZED and ZC702]].
+Make sure you have an HDMI monitor connected to the ZedBoard, plug in the SD Card and power on the board.
+If everything is correct, the system should boot up. If you don't have an HDMI monitor, connect to the board via UART, Baud Rate 115200.
+There are 2 ways to test the driver.
+    * Using the terminal window
+    * Using a serial terminal
+===== Using the terminal window =====
+Open a new terminal window by pressing **Ctrl+Alt+T**.
+Navigate to the location of the device and identify it using the following commands:
+<code>
+cd /sys/bus/spi/devices/
+ls
+spi32765.0  spi32766.0
+cd spi32766.0
+ls
+driver  modalias  power  rdac0  subsystem  uevent
+cat modalias
+spi:ad5160
+</code>
+If the **cat modalias** command doesn't return **spi:ad5160**, then change the number of the spi device, and check again.
+<code>
+cd ..
+cd spi32765.0
+cat modalias
+</code>
+To see the list of options that the AD5160 driver provides, type:
+<code>
+ls
+driver  modalias  power  rdac0  subsystem  uevent
+</code>
+To set the rdac resistance, type:
+<code>
+echo 100 > rdac0
+</code>
+To read the set rdac value, type:
+<code>
+cat rdac0
+</code>
+{{:resources:fpga:xilinx:pmod:ad5160_linaro_terminal.jpg?600|AD5628 Set Voltage from Terminal}}
+The commands written above can also be used if not using an HDMI monitor and a wireless keyboard, by using a serial terminal, and typing the commands after the system boot-up is complete.
+{{:resources:fpga:xilinx:pmod:ad5160_linux_serial.jpg?600|AD5628 Read Voltage from Serial Terminal}}
