openmp c6678 helloworld example

Q1:we could not find  the  source code of init_navigator() function ,and did not know the operation of the init_navigator() function . How to solve the CPU abort  and why?

The following is our part of project：

1）we use the TI default platform as our  RTSC platform,and the RTSC cfg configuration is as follows：

mcsdk:mcsdk_2_01_02_06
xdctools:xdctools_3_24_05_48
IPC: ipc_1_24_03_32
BIOS：bios_6_33_06_50
OpenMP：omp_1_01_03_02

2） The DDR'S access space on our custom board is from 0x80000000 to 0xFFFFFFFF,totally 2GB,and does it have some questions to use the TI EVM's platform?

3) The cfg configuration file of our project  is as follows:

Compared to the TI default CFG,our cfg adds  some  content ,they are between the 
///////////////////////////////////////////////////(i)

and

///////////////////////////////////////////////////(i)
(1) ,(2) (3) (4) are referred to our previous program ,which we use to run SYS/BIOS configuration onour custom board .Especifically,our custom board is different from the EVM,and mang cfg files needs  our own driver to work completely ,and before the boot of main(),we ran to the C6678_init() function ,instead of  performming  the GEL file.And the C6678_init() function's mainly code is as follows:

void C6678_init()
{

if(DNUM==0)
{
//初始化PLL
if (C6678_Pll_Init(PLATFORM_PLL1_PLLM_val)!= TRUE)
{
// printf("PLL failed to initialize!!!!!!!!!!!!!!!!!!!!!!!!! \n" );
}
else
{
// printf("PLL successd to initialize\n" );
}

C6678_Power_UpDomains();
C6678_Ecc_Enable();
}

//使能TIMER
C6678_TimeCounter_Enable();

if(DNUM==0)
{
//初始化DDR
if (C6678_Ddr3_Init(PLLM_DDR3,DDR3_TYPE)!= TRUE)
{
// printf("*******DDR3 failed to initialize!******* \n" );
}
else
{
// printf("*******DDR3 successed to initialize!******* \n" );
}
}

}
C6678_init() function's mainly functions are  ：
1) configure the PLL of CPU
2) initialize the DDR on the board
