wince5.0开始菜单SUSPEND没有反应 [复制链接]

我是用S3C2410　WINCE5.0，在开始菜单点击SUSPEND，系统没有挂起，也没有什么异样，从DEBUG信息版本到信息有如下输出：

我在F:\WINCE500\PLATFORM\COMMON\SRC\ARM\SAMSUNG\S3C2410X\POWER\off.c　OEMPowerOff()函数中添加提示信息也没有显示，好像是根本就没有调用这个函数，不知道问题出在哪里？平台中我已经添加了POWER MAGAGEMENT(FULL),请高人指点，谢谢！

是不是电源管理那块没有挂上去啊。关注下。这个问题比较有意思。

1.检查下BSP包是否有电源管理部分，是否确认添加到你的项目中了
2.检查code。。。。。加入相关打印信息检测是否跑到程序。比如找关键字 suspend。。。

自己加code 相关原理在eeworld的老帖有。

看打印信息，应该是在调用OEMPowerOff之前调用了各个驱动的××_PowerDown函数。

1、有可能OEMPowerOff中打印函数添加不合理，导致打印信息出不来。

2、OEMPowerOff实现不完全，其中涉及到保存寄存器、设置唤醒源、置CPU为休眠等步骤。具体可以参考网上帖子。

3、调试跟踪下，看看OEMPowerOff函数是否可以被顺利调用，是不是某些全局指针发生错误，导致调用不成功！

个人意见，共同学习！
