Getting Started with EM Software Development Platform

Info

Consider reading these guides firstly:

• Configuring EM Software Development Platform
• Installing WinUSB driver on Windows

Creating the Project

Select File → New → Project.. and choose C Project. A list of ARC projects will appear. Choose any ARC EM Starter Kit "Hello World" project from the ARC EM SDP Projects group.

After creating the project, a simple "Hello, World!" program will be created:

/* Print a greeting on UART output and exit. */

#include <stdio.h>

int main(int argc, char *argv[])
{
    printf("Hello, World!\n\r");
    return 0;
}

Building the Project

Do right click on a project in Project Explorer ans choose Build Project. The project will be built with this output:

make all

Creating a Debug Configuration

Do right click on projects's name in Project Explorer and choose Debug As → Debug Configurations.... Then do right click on ARC C/C++ application and choose New Configuration. Here is a main window of the debug configuration:

Ensure that a correct project and binary are selected. Navigate to Main tab and Gdbserver Settings inner tab:

Choose JTAG via OpenOCD as ARC GDB Server and EM Software Development Platform as a development system (use a corresponding one for your case). Then click on Apply.

Configuring a Serial Terminal

Navigate to Terminal inner tab of Main tab and select a COM port for the board. Eclipse automatically detects all available COM ports. In my case it's /dev/ttyUSB6.

On Windows you can find the exact number in Device Manager (it corresponds to USB Serial Port device):

On Linux a serial device for EM Software Development Platform is usually /dev/ttyUSB1 if there are no other serial devices connected to the host.

Debugging the Project

Open the debug configuration in Debug Configurations windows and click on Debug button. The Debug perspective will be opened:

Use Step Over button to step over printf function and select Terminal in the bottom of the window. "Hello world!" string will be printed:
