 If programming was successful, you should be seeing messages appear on the terminal window as shown in the figure below. After programming the ADXRS453 device, the program will automatically send the recommended initialization sequence. Once complete, it will start to print current angles/second rotation on Z-Axis on the UART.

+====== Linux Device Driver ======
+Connect PmodGYRO2 to the JA1 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/legacy/Pmods/PmodGYRO2/dts|PmodGYRO2 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
+adxrs450
+</code>
+If the **cat name** command doesn't return **adxrs453**, 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 ADXRS453 driver provides, type:
+<code>
+ls
+dev                                     in_anglvel_z_scale  name       uevent
+in_anglvel_z_quadrature_correction_raw  in_temp0_raw        power
+in_anglvel_z_raw                        in_temp0_scale      subsystem
+</code>
+To read the raw Z angle, type:
+<code>
+cat in_anglvel_z_raw
+</code>
+To read the raw temperature, type:
+<code>
+cat in_temp0_raw
+</code>
+{{:resources:fpga:xilinx:pmod:adxrs453_linaro_terminal.jpg?600|ADXRS453 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.
