一般中断子函数里做的事情越烧越好，这样防止丢中断。能否把SRIO传输的函数放到中断子程序外面运行？

回复 Shine:
那就是在中断中调用任务了，中断并不是执行一次，而是每次都要执行，如果调用任务的话怎么弄？
Shine：
回复 user5301336:
可以在中断子程序中置个标志位。

回复 user5301336:
请问是什么意思？我又试了试，DIO传输那个函数还是不行

回复 user5301336:
在中断里flag=1, 主程序里通过判断flag是否执行功能函数。
user5301336：
回复 Shine:
明白您的意思了，我试试~~但是还有个问题呀，执行完BIOS_Start之后，程序等待上位机的信号，开始执行Task，我要功能函数写在什么地方呢？还是直接另外建一个文件，在里面自定义个功能函数？

我在上面的HWI中的ISR中调用SRIO的DIO程序，出现了，下面的错误，ti.sysbios.gates.GateMutex:line 97 assertion failure:A badcontext: bad calling context. See gateMutex API doc for detail 。
查了资料，好像是在HWI中调用了molloc，建议创建新的任务，执行任务，这个我要怎么弄？不太懂
