TQ2416能进入Sleep，怎么唤醒不了？？？

跑的Linux，用光盘里的PM驱动，sleep跑进去了，用底板上的按键怎么唤醒不了，不知道用外部中断究竟是怎么实现唤醒的～ 进行sleep前，中断被屏蔽了没。把中断打开，再sleep吧 米+油 发表于 2012-12-26 14:01 static/image/common/back.gif

唤醒源设置对了么？ intmask在上电后，默认是开，还是关，看一下，关了就要把中断先打开，哥们 embedsky_lhh 发表于 2012-12-26 14:04 static/image/common/back.gif

唤醒源没设置，还有就是唤醒的外部中断开了没？ embedsky_lhh 发表于 2012-12-26 15:12 static/image/common/back.gif

怎么知道唤醒源有没有设置，感觉都设置了的啊？
打开外部中断就是那个EINTMASK吧？ dj5443 发表于 2012-12-26 15:22 static/image/common/back.gif

需要仔细阅读芯片手册Power那节，
已能实现进入sleep模式，并通过外部中断（底板上的按键）成功唤醒，之前不成功是因为把按键的驱动给屏蔽了！多谢楼上两位朋友提供帮助～
