ucos运行死机

a4615800

ucos2中,我用的是原子兄的综合实验为基础 加了CAN通讯进去,在单布调试的时候,进入函数里面的时候出来没问题,但是一旦F10直接运行函数的时候就死机跳到以下界面:

我看了下,排除了中断服务函数没有找到主体的情况.
每次经过这个库函数就死机了:

但是单步F11进入以后出来没问题,经过他以后继续F10经过下一个函数的时候就死机了.前面F10的时候不会有问题.

在线等.已经为这问题烦恼了好几天了.

不好给答案。建议一个一个查。

库函数里面就是操作寄存器了.进去单步调试的时候他不会出问题,只有F10直接运行他的时候才会死机,所以不好查.

如果屏蔽掉用这个函数的话 运行是正常的.

很奇怪的是,我在调试的时候,527行不可以设置断点,其他行都可以.

a4615800

具体是到:

请求传输的时候,运行到这里就卡死了.正常情况 请求传输以后会打开发送中断,下面是我的发送中断函数:

这个是发送中断主体函数.不知道名字有没有问题.我是从startup_stm32f10x_hd.s里面复制的名字过来的.

卡死了,死到什么地方了？

正点原子

先简单化问题.
将不必要的东西全去掉,排除法找问题.

看别人的东西就是累

对楼主的时序不是很清楚，麻烦描述一下。

可能的问题点：

1、中断标志位；
2、中断调用不合理。

弃用UCOSII了.调试太麻烦了
