WhyCan Forum(哇酷开发者社区)

看下应该产生什么信息， 然后代码里面搜索一下，找到相关代码, 前后加上 printk, 看为何没有进入。

加了也调试过，不是驱动没加，驱动加载了，那个DTS也是标准的，无须修改。但编译后的结果是它根本就没有产生 电池信息。

不是这样的，我原来的DTS有写一个中断信息，但因为我们的芯片没有接中断IO，所以本质上是没有意义的。而且我也打电话问过代理商，不接IRQ是没有问题的，可以用。

有没有QQ？或才到晕哥的群里聊啊。
首先是有骗过去的。但是也是空的啊

可以骗过去，但依然没什么用

这个是打印信息，中间我自己添加了一些。打印出来的。它根本最后 都用了regulator-dummy

是的，非常尴尬。。。。。。

你好搂住,用axp这个电源方案 ,又没有遇到过系统插着串口线再上电,电源没有输出的问题?
