+====== Linux Device Driver ======
+Connect PmodDA4 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/PmodDA4/dts|PmodDA4 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/iio/devices/
+ls
+iio:device0 iio:device1 trigger0
+cd iio\:device0
+cat name
+ad5628-1
+</code>
+If the **cat name** command doesn't return **ad5628-1**, then change the number of the iio:device, and check again.
+<code>
+cd ..
+cd iio\:device1
+cat name
+</code>
+To see the list of options that the AD5628 driver provides, type:
+<code>
+ls
+dev                          out_voltage4_powerdown_mode
+name                         out_voltage4_raw
+out_voltage0_powerdown       out_voltage4_scale
+out_voltage0_powerdown_mode  out_voltage5_powerdown
+out_voltage0_raw             out_voltage5_powerdown_mode
+out_voltage0_scale           out_voltage5_raw
+out_voltage1_powerdown       out_voltage5_scale
+out_voltage1_powerdown_mode  out_voltage6_powerdown
+out_voltage1_raw             out_voltage6_powerdown_mode
+out_voltage1_scale           out_voltage6_raw
+out_voltage2_powerdown       out_voltage6_scale
+out_voltage2_powerdown_mode  out_voltage7_powerdown
+out_voltage2_raw             out_voltage7_powerdown_mode
+out_voltage2_scale           out_voltage7_raw
+out_voltage3_powerdown       out_voltage7_scale
+out_voltage3_powerdown_mode  out_voltage_powerdown_mode_available
+out_voltage3_raw             power
+out_voltage3_scale           subsystem
+out_voltage4_powerdown       uevent
+</code>
+To set the raw output voltage for channel A, type:
+<code>
+echo 1200 > out_voltage0_raw
+</code>
+To check that the raw output voltage has been set, you can type:
+<code>
+cat out_voltage0_raw
+</code>
+If you want to set the voltage for another channel, replace **out_voltage0_raw** with, for example, **out_voltage1_raw**.
+{{:resources:fpga:xilinx:pmod:ad5628_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.
