openmp c6678 helloworld example

I do an experiment on ccs,on which I run an openmp program ,but I met some questions ,please help me.I run the Helloworld Demo on general board not on the EVM,the project could run successfully on simulator ,but failed on emulator,with the mistake ipc_attach ,and how to solve it?Besides ,I have some additional questions.

  1. I can not find the omp_config_oe66,and where is the library.  
  2.  . I used the ti.omp.examples.platforms.evm.6678 ,and what is the relationship between it and ti/omp-1-01-03-02/packages/ti/omp/platform/evm6678?  
  3. I want to know how to modify the platform ,and I want to use our own general board .Because the DDR’S address  range on evm is from 0x80000000 to 0x9fffffff,but on our general board is from ox80000000 to 0xffffffff .And the MSMSRAM_Nocache on EVM is oxa0100000,but on the general board is 0x50000000.How to modify the platform ?

        4.The tools I used are as the following :

Compiler version :TI v7.4.1

IPC           :1.25.0.04

MCSDK PDK TMS320C6678 : 1.1.2.6

OpenMP BIOS runtime library:1.1.3.0.2

SYS/BIOS     :6.34.2.18

Are there problems about the tools I used?

    Welcome to the TI E2E forum. I hope you will find many good answers here and in the TI.com documents and in the TI Wiki Pages (for processor issues). Be sure to search those for helpful information and to browse for the questions others may have asked on similar topics (e2e.ti.com). Please refer the links below my signautre.
    We will get back shortly on the above query. Thank you for your patience.
