20250927让荣品RD-RK3588-MID开发板的Android13系统在uboot下关闭背光充电
2025/9/27 18:20
缘起：搞不定在关机充电的时候：在uboot状态下显示电量的百分比。PM要求直接关闭LCD屏的电量显示图片。
我们有电量指示灯带的！这个功能以后再解决了！
不过现在还是有一个小瑕疵：插+12V适配器充电的时候，背光会闪一下：亮一下就关闭了！
如果要彻底彻底，还是有一点点工作量的！
在RD-RK3588-MID开发板中 充电的时候 有充电图标。没有电量 百分比？
请帮忙加一下 充电百分比 ?@权
在设置 电池 百分比显示
这个是 关机充电的时候。
现在 只有 图标。没有百分比！
关机后充电显示吗？这种加不了实时数字，只能加图片。你们可以根据自己的需求进行开发
PRO-RK3566+buildroot
我司 吊舱 和 竞品 在实现同样的功能 ，但是我司产品 在3.3V下电流高1A。功耗大很多。
该从哪里分析问题？比如 CPU/GPU/NPU占用率？
请提供查看占用率的方法？?@陈威
