CCS/CCSTUDIO-C2000: blinky example problem

Part Number: CCSTUDIO-C2000
Other Parts Discussed in Thread: CONTROLSUITE

Tool/software: Code Composer Studio

I am using CCSV5 for the first time and want to run the blinky example.  When I try to build the project, I got some errors. 

error #10234-D: unresolved symbols remain
error #10010: errors encountered during linking; "Blinky.out" not built

the following is the program and console output

//! <h1>Timer based blinking LED(timed_led_blink)</h1>
//!
//! This example configures CPU Timer0 for a 500 msec period, and toggles the GPIO34
//! LED once per interrupt. For testing purposes, this example
//! also increments a counter each time the timer asserts an interrupt.
//!
//! \b Watch \b Variables \n
//! - CpuTimer0.InterruptCount
//!
//! \b External \b Connections \n
//! Monitor the GPIO34 LED blink on (for 500 msec) and off (for 500 msec) on
//! the 2806x control card.

#include "DSP28x_Project.h" // Device Headerfile and Examples Include File

// Prototype statements for functions found within this file.
__interrupt void cpu_timer0_isr(void);

void main(void)
{

// Step 1. Initialize System Control:
// PLL, WatchDog, enable Peripheral Clocks
// This example function is found in the F2806x_SysCtrl.c file.
InitSysCtrl();

// Step 2. Initalize GPIO:
// This example function is found in the F2806x_Gpio.c file and
// illustrates how to set the GPIO to it's default state.
// InitGpio(); // Skipped for this example


// Step 3. Clear all interrupts and initialize PIE vector table:
// Disable CPU interrupts
DINT;

// Initialize the PIE control registers to their default state.
// The default state is all PIE interrupts disabled and flags
// are cleared.
// This function is found in the F2806x_PieCtrl.c file.
InitPieCtrl();

// Disable CPU interrupts and clear all CPU interrupt flags:
IER = 0x0000;
IFR = 0x0000;

// Initialize the PIE vector table with pointers to the shell Interrupt
// Service Routines (ISR).
// This will populate the entire table, even if the interrupt
// is not used in this example. This is useful for debug purposes.
// The shell ISR routines are found in F2806x_DefaultIsr.c.
// This function is found in F2806x_PieVect.c.
InitPieVectTable();

// Interrupts that are used in this example are re-mapped to
// ISR functions found within this file.
EALLOW; // This is needed to write to EALLOW protected registers
PieVectTable.TINT0 = &cpu_timer0_isr;
EDIS; // This is needed to disable write to EALLOW protected registers

// Step 4. Initialize the Device Peripheral. This function can be
// found in F2806x_CpuTimers.c
InitCpuTimers(); // For this example, only initialize the Cpu Timers
// Configure CPU-Timer 0 to interrupt every 500 milliseconds:
// 80MHz CPU Freq, 50 millisecond Period (in uSeconds)
ConfigCpuTimer(&CpuTimer0, 80, 500000);


// To ensure precise timing, use write-only instructions to write to the entire register. Therefore, if any
// of the configuration bits are changed in ConfigCpuTimer and InitCpuTimers (in F2806x_CpuTimers.h), the
// below settings must also be updated.

CpuTimer0Regs.TCR.all = 0x4001; // Use write-only instruction to set TSS bit = 0

// Step 5. User specific code, enable interrupts:

// Configure GPIO34 as a GPIO output pin
EALLOW;
GpioCtrlRegs.GPBMUX1.bit.GPIO34 = 0;
GpioCtrlRegs.GPBDIR.bit.GPIO34 = 1;
EDIS;

// Enable CPU INT1 which is connected to CPU-Timer 0:
IER |= M_INT1;

// Enable TINT0 in the PIE: Group 1 interrupt 7
PieCtrlRegs.PIEIER1.bit.INTx7 = 1;

// Enable global Interrupts and higher priority real-time debug events:
EINT; // Enable Global interrupt INTM
ERTM; // Enable Global realtime interrupt DBGM

// Step 6. IDLE loop. Just sit and loop forever (optional):
for(;;);
}


__interrupt void cpu_timer0_isr(void)
{
CpuTimer0.InterruptCount++;
GpioDataRegs.GPBTOGGLE.bit.GPIO34 = 1; // Toggle GPIO34 once per 500 milliseconds
// Acknowledge this interrupt to receive more interrupts from group 1
PieCtrlRegs.PIEACK.all = PIEACK_GROUP1;
}
