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。
