您好： 我使用的是C6678的开发板，仿真器XDS100v，目前只在软件仿真。 任务是：想要完成多核图像处理，使用主核对图像进行分块，从核对每个数据块进行处理，再使用主核对各个处理结果进行整合。 问题是：使用notify（）的例程，在从核程序中加入自己编写的子函数，在对数据块完成处理以后，程序卡停，不能激活主核进行结果整合。（尝试加入只有打印信息的子函数，可以完成主从核之间通信，没有问题。） 卡了很久很久了，找不到原因，希望能尽快解答，万分感谢！ DEBUG结果如图：（请问会停在这里的原因是什么？）
没有从核2的sent 打印信息，也没有主核0的最后接收打印信息
使用test子函数，可以看到完整的打印信息：
代码如下：
