CCS/TM4C123GH6PM: Accessing Variables from CCS in .js script

Hello,

You can use the DSS APIs to get the address of "m" and then read the data at that address.

var addr = debugSession.symbol.getAddress("m");

var val = debugSession.memory.readWord(addr);

Thanks

Mr Ki, I am again struck at a point where i have to run a particular test case function "port_read" who i want to call

#include <stdint.h>
#include <stdbool.h>
#include "inc/hw_memmap.h"
#include "inc/hw_types.h"
#include "driverlib/sysctl.h"
#include "driverlib/gpio.h"
int  port_read(void);

int x=0;
int y=0;

int main(void)
{
SysCtlClockSet(SYSCTL_SYSDIV_5|SYSCTL_USE_PLL|SYSCTL_XTAL_16MHZ|SYSCTL_OSC_MAIN);
SysCtlPeripheralEnable(SYSCTL_PERIPH_GPIOF);
GPIOPinTypeGPIOOutput(GPIO_PORTF_BASE, 2);
GPIOPinWrite(GPIO_PORTF_BASE, GPIO_PIN_1, 2);
//x=port_read();

}


int  port_read(void)
{
	return GPIOPinRead(GPIO_PORTF_BASE, GPIO_PIN_1);

}

My script is as follows 

// Import the DSS packages into our namespace to save on typing
importPackage(Packages.com.ti.debug.engine.scripting);
importPackage(Packages.com.ti.ccstudio.scripting.environment);
importPackage(Packages.java.lang);
print("New Code Under Execution");
//buildProject "red_led";

// Modify these variables to match your environment. Use forward slashes
var ccs5InstallDir = "C:/ti";
var DSSWorkshopDir = "C:/CCSWorkshop/dss"
var deviceCCXMLFile = DSSWorkshopDir + "/lab1/StellarisLaunchPad.ccxml";

var programToLoad = DSSWorkshopDir + "/workspace/Simple_Trial3/Debug/Simple_Trial3.out";

var logFile = DSSWorkshopDir + "/workspace/Simple_Trial3/log.xml";

// Create our scripting environment object - which is the main entry point 
// into any script and the factory for creating other Scriptable Servers and Sessions
var script = ScriptingEnvironment.instance();

// Create a log file in the current directory to log script execution
script.traceBegin(logFile, ccs5InstallDir + "/ccsv6/ccs_base/scripting/examples/DebugServerExamples/DefaultStylesheet.xsl");

// Set trace levels for console and logs
script.traceSetConsoleLevel(TraceLevel.INFO);
script.traceSetFileLevel(TraceLevel.ALL);

script.traceWrite("Begin scripting session");

// Get the Debug Server and start a Debug Session
var debugServer = script.getServer("DebugServer.1");
debugServer.setConfig(deviceCCXMLFile);
var debugSession = debugServer.openSession(".*");

// Check to see if target is already connected
// target.isConnected() API will return 'true' is connected
if (!debugSession.target.isConnected())
{
  // Connect to the CPU
  debugSession.target.connect();
}

// Load a program
debugSession.memory.loadProgram(programToLoad);
debugSession.breakpoint.removeAll();

// Run the target
debugSession.target.run();
print("Running");



var address1 = debugSession.symbol.getAddress("port_read");
debugSession.memory.writeRegister("PC", address1);
debugSession.target.run();






// All done
debugServer.stop();

script.traceWrite("End scripting session");

// Stop logging and exit.
script.traceEnd();

When i run the code I am getting following problems 

New Code Under Execution
Running
Unable to get address for symbol: port_read (C:\CCSWorkshop\dss\workspace\Simple_Trial3\lab3.js#57)

Tried many times .. But it is hanging at that line 57 for a very long time and throwing me the message i pasted above
