-====== Hello World on the Digilent Zybo Board ======
-This example will demonstrate how to use the deep compiler to translate a simple Java program and run it on a [[https://wiki.ntb.ch/infoportal/embedded_systems/zynq7000/zybo|Zybo board]].
-  - Start eclipse, choose a new workspace and open the deep perspective with //Window -> Open Perspective -> Other -> Deep//.
-  - Create a new deep project with //File// -> //New// -> select //Project..., Deep -> //select// Deep Project//. \\ {{:newdeepproject.png?300|}}
-  - On the Target Library wizard page you have to choose where the deep target runtime library is located. You can use the default library path or uncheck the box and browse to the location where you've installed the library. You can always set the default library path in [[eclipse:perspective#Setting_Deep_Preferences|deep Perspective and deep Preferences]]. Click //Next//. \\ {{targetlibrary.png?300|}}
-   - Target Configuration:
-    - Select a board: //Zybo Zynq-7000 digilent evm//
-    - Select a operating System: //Simple Tasking System for ARM//
-    - Select a programmer: //OpenOCD//
-    - Select programmer options: //localhost_4444//
-    - Select the checkbox //Create image file// and choose the location to save the image file and the desired image file format, preferably //BIN//. Default save location is the project folder. Please make sure that the file path does not include spaces or hyphens. \\  {{targetconfigurationzybo.png?300|}}
-  - Project name:
-    - Choose a project name (no spaces, no special characters such as "umlauts")
-    - Use default location or choose a location \\ {{{{projectname.png?300|}}
-  - //Finish// creates the project
-  - The empty project will show on the left side in the package explorer.\\ {{emptyproject.png?150|}}
-  - By right-clicking on the source folder (src) in the package explorer choose //New// -> //Package// and add package name, e.g. //test//.
-  - By right-clicking on the newly created package choose //New// -> //Class// and enter class name //HelloWorld//.
-  - Open class and enter source code:<code java>
-import java.io.PrintStream;
-import ch.ntb.inf.deep.runtime.zynq7000.driver.UART;
-public class HelloWorld {
-	static {
-		// Initialize UART (115200 8N1)
-		UART uart = UART.getInstance(UART.pUART1);
-		uart.start(115200, UART.NO_PARITY, (short)8);
-		// Use the uart for stdout
-		System.out = new PrintStream(uart.out);
-		// Print a string to the stdout
-		System.out.println("Hello world");
-	}
-}
-</code>
-  - Open deep project file //HelloWorld.deep//. This file can be found in the root of the project.
-  - Add the newly created class to //rootclasses//. It should then look like this:<code>
-#deep-1
-meta {
-	version = "Mon Jan 05 12:40:12 CET 2015";
-	description = "deep project file for HelloWorld";
-}
-project HelloWorld {
-	libpath = "I:\deep\lib";
-	boardtype = Zybo;
-	ostype = sts_arm;
-	programmertype = openOCD;
-	programmeropts = localhost_4444;
-	imgfile = "D:\work\HelloWorld.bin";
-	imgformat = BIN;
-#	pl_file = none;
-#	enter names of rootclasses, e.g.
-#	rootclasses = "test.MyFirstTestClass","other.MySecondTestClass";
-	rootclasses = "test.HelloWorld";
-}
-</code>
-  - Connect the hardware to your host machine by an USB cable (J11). This applies power to the target.
-  - Make sure that you select the proper driver for your adapter [[https://wiki.ntb.ch/infoportal/embedded_systems/jtaghs3/start]].
-  - Start [[https://deepjava.org/openocd/starting_openocd|OpenOCD]].
-  - Open a terminal program such as ''putty'' or ''realterm''. Alternatively open a terminal program as an eclipse view. Select the appropriate serial port number. Check your host operating settings for this number.
-  - Create a new run configuration by marking the project file //HelloWorld.deep//. Then, right-click on it and choose //Run As -> Deep Application//. If you already created such a run configuration you can select from the pulldown menu of the run-button. \\ {{runas_context.png?280|}} {{ runas_pulldown.png?280|}}
-  - //Run// will compile, link and download the image file. For downloading and debugging [[openocd:start|OpenOCD]] will be used. Make sure to have it installed.
-  - The terminal window will show //Hello, World//.
-  - With {{run.jpg}} you can recompile and rerun the program.
