20250912在荣品RD-RK3588-MID开发板的Android13系统下在接电脑的时候禁止充电
2025/9/12 10:21
缘起：某人的电脑接荣品RD-RK3588-MID开发板的时候做APK开发板的时候，通过Android Studio连接荣品RD-RK3588-MID开发板。
经常断联/时断时续。投诉了/抱怨了好久。
我司APK应用开发的电脑的USB口的电压不稳，每次 接他的电脑，android13 的LCD屏就不停的出现 水波纹。这个时候他的电脑ADB会断掉
这时候 我只能 给 bq25703配置成为 80度，禁止充电。
请问 如何 在RD-RK3588-MID为device 的时候禁止充电。
或者 是 +5V输入的时候 禁止充电？?@DreamSky
在dts配置25703里有PD配置，把5V配置为0mA或注释掉。
请问是这里吧：
ti,otg-current = <3000000>;//<6350000>;
不是，我记错了，在fusb302那里
5000
搜索到2个5000
这次应该找对地方了。
5V/9V/12V/20V？
就是这里了
对
这里有2个5000，改哪个？
我改了上面面哪一个。还是显示 满速充电？
注释掉type-c里的5000
Z:\rk-android13-20250818RD-RK3588-MID\kernel-5.10\arch\arm64\boot\dts\rockchip\rk3588\rp-usb-typec-rk3588.dtsi
根据 名字，只有 rp-usb-typec-rk3588.dtsi 这个 DTSI文件 是 配置 type-C的。
查找 之后，根据csdn博文。注释了一个。但是 出现 慢速充电/未在充电支架反复横跳。
不知道 是 现实问题？还是没有配置好。【ADB可用】
你最终是需要使用5V充电的，当前只是为是适配ADB，ADB处理好了就可以开放5V充电。
我们的板子连电脑USB，ADB是不会断开或反复充电的。
我司 APK应用开发的电脑 只有他的电脑有问题。
估计是 USB的电压不稳。
请问 我改哪一个5000？我找到4个5000了
目前只是开发应用的电脑处理好了就行了，加上其他电脑是正常的，你不应该为了一些不正常的东西去浪费时间，PD就是配置充电电压与充电过流，去掉5V就可以了。
很多电脑也会这样
不止是一台电脑
上次不是给你看了吗？有三台电脑也会这样
这样可以改充电电流，之前针对这个问题说明了，检测到是ADB状态，设置充电电流为0。

source-pdos =

sink-pdos是指我们做sink(耗电方，即外接充电器)时候的充电能力，一般包括电压和电流。
source-pods是指我们做充电方对外充电的时候支持的pd充电能力，这个5000和1000是代表5v-1a。
