您好：大致是下面的情况：

void taskfunc2()

{

//执行一些线程初始化之后，堵塞这个线程

}

void taskfunc1()

{

if(core0) {

task_create();//这里创建一个线程，优先级高于当前，就叫taskfunc2()吧

} else{

task_create();//这里创建一个线程，优先级高于当前，就叫taskfunc2()吧 }

}

所有段都放在DDR3里面，8核进入taskfunc1()线程函数，然后通过Notify机制，8个核依次创建taskfunc2()线程，但是发现core0能够创建taskfunc2()并立即进入完成初始化返回，但是其他核就会返回如下的错误，请问这是什么原因？
