TI中文支持网1. 现象
运行SYS/BIOS (TI-RTOS Kernel) v6.45 User's Guide的例子，3.8 Example Using Hwi, Swi, and Task Threads，第100页~104页。
连接BeagleboneBlak正常，build正确，执行时提示如下错误，

xdc.runtime.Error.raise: terminating execution
发现程序停在函数 static void loader_exit(void){}处。
而按照手册说法，正确的执行结果会输出：
Starting HwiSwiTask example.
In taskFxn pending on Semaphore.
In clk1Fxn, arg = 1.
In clk1Fxn, arg = 2.
In clk1Fxn, arg = 3.
In clk1Fxn, arg = 4.
In clk2Fxn, posting Semaphore.
In taskFxn returned from Semaphore
这是为何。
2. 软件环境

请工程师们给点解决方案，谢谢啦。
