pxa270休眠唤醒的新进展，高手帮忙分析下，感谢。

release版与debug版的区别在哪？把debug版本下的display驱动放到release下编译照样出样下列错误。。。

这是release版本的NK，总是死在这个地方。编了个debug版本的，居然过去了。不知道怎么回事。高手帮忙分析一下吧。感谢。。。。

看起来已经唤醒了。

我的想法， 能不能排除一下， 先把电影管理的驱动去掉， 先排除这个原因， 指定是pwr等驱动。

DATASHEET里的说明,要确保1显示完当前buffer,2外设都是idle.相应clock都停止.3写ox7到pmu的寄存器.如果没有前边两步,就出现你的错误了.我也曾经遇到过.后来改好了.

现在发现DEBUG版本唤醒后也是死了。屏没有显示了。。
1.显示完当前buffer???请问我要怎么样确认呢，
2.外设都是idle.相应clock都停止.，是不是suspend的时候，在每个驱动的XXX_PowerDown函数下要的CLOCK都关掉.
大侠能说得详细一点吗？这问题困住我都一个月了了。。过不去啊。。。。
