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？

逻辑是对的，对了一下原理图，vdc应该只有dc上电时才有一瞬间的电压导通启动，应该通过其他电路放电
查看手册，可以通过PMIC_ON_SOURCE 寄存器来获取启动方式
可以获取0xf5第 6 位的值来判定目前是什么方式启动，如果是1 就是dc触发开机，就不跑power判定逻辑
