 +====== 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
 +1200
 +</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.
