C6678 NDK run exception

Other Parts Discussed in Thread: SYSBIOS

hello,

My project include NDK to transfer data for core0, and core1~core7 process the data from core0, then core transfer data that have been process by core1~7 to PC.

My project process:

 void main()

{

  SysInit();

BIOS_start ();

}

Bios will create a task StackTest(), it is the NDK initiation function, Because only core0 run NDK, so just core0 to init NDK, and other core wait core0's message! below is

the code

int StackTest()

{

    if(DNUM == 0)

   {

     //  init ndk ,the same with the hellowolrd demo

   }

else

{

    while(1)

{

  while(flag != 1);//core 0 will set the flag = 1

  flag  = 0;    

   data_process();

}

}

}

 

 

I run in 4 cores, core0 trasnfer ,core1~3 process, But When the project run a while, core 1 print this:

only core1 print this message, other cores all OK, I am not sure where is the problem!

Thanks!
