Getting Started with EM Starter Kit

Creating Hello World project for EM SK

1. Select File >New >C Project

   

   Creating a new C project

   The C Project window should have several ARC project types: ARC Cross ELF32 Target Application, ARC Cross ELF32 Target Static Library, AXS10x Projects and EM Starter Kit Projects. Select EM Starter Kit Projects. This project type is available only if ARC EM toolchain compiler can be found either in PATH environment variable or in ../bin/ directory relative to Eclipse executable.

2. Enter a project name

   

   C Project Creation Dialog

   1. Under EM Starter Kit Projects select Hello World for EM SK 2.1 Project (or Hello World for EM SK 1.1 depending on your EM SK version). This Hello World project is an example project that comes with the EM Starter Kit Software and uses the UART on the EM Starter Kit to display output. To see output printer to UART, connection to serial port should be established. By default Eclipse for ARC will automatically connect to available serial port, but that feature can be disabled and in that case refer to the EM Starter Kit Getting Started for instructions on how to connect to the UART on the EM Starter Kit board using Putty.

   2. Fill in project name and click Finish or Next if you want to fill in additional information.

The resulting Hello World project created in Eclipse is:

Final Hello World Project in Eclipse

Building the project

1. Right click on the Hello World project and select Build Project from the pop-up menu

2. Review the build output log in the Eclipse console tab to confirm success:

Debugging the project

Once the project is successfully compiled by ARC GCC, you can debug the resulting executable on the EM Starter Kit board.

To debug the project, create a new debug configuration.

1. Select Debug Configurations from the Run menu or by clicking on the down arrow next to the bug icon:

   

   Debug Configurations

2. Double click on the ARC C/C++ Application or click on the top left icon to create a new debug configuration for the project:

3. Select a name for the new debug configuration (by default, it equals the project name followed by "Debug").

   

   New debug Configuration

4. Click the Debugger tab and select Gdbserver Settings page.

   Default values in the Debugger tab for JTAG via OpenOCD

   Select EM Starter Kit v2.x or EM Starter Kit v1.x as development system depending on your EM SK version.

   The COM Ports picklist at Terminal tab shows the value for Digilent USB Serial Port from the Windows registry. You can modify the value as desired, but the selection must match the port number in Device and Printers as shown in below.

5. Click the Debug button in the Debug configurations dialog to initiate debug session.

   This action automatically launches the Serial terminal and OpenOCD applications in the background and connects to the UART on the EM Starter Kit board.

6. Click Yes in the confirmation dialog to switch to the Debug perspective
