20250607在荣品的PRO-RK3566开发板的Android13系统下实现长按开机之后出现插入适配器不会自动启动的问题的解决 2025/6/7 17:20

缘起： 1、根据RK809的DATASHEET，短按开机【100ms/500ms】/长按关机，长按关机。6s/8s/10s 我在网上找到的DATASHEET是V1.0的，据说有V1.4的或者更新的？如果有，方便的话，发一下。

2、我们希望长按2s开机。如果 RK809的开机模式是写死了。我司需要等待 2s时间【以防误操作/误触发】

可以使用这个上电逻辑不？

先让 RK809检测到500ms 开机指令，如果检测到，先【清除掉寄存器中的开机指示？】，然后让 RK809等待1.5s == 1500ms，现在在检测电源键是否还是按下的。如果是的。走正常的开机逻辑。如果不是，就判定为误操作，关机了。

或者您这边有更好的上电逻辑/建议？

【已知的/已经测试出来的BUG：】

这个PATCH可以实现按键2s 开机。但是有一个问题。

现在插电/适配器之后，RK3566不会自动开机。追问一下。是否可以解决这个问题？
