【Android10】【AIO-3399J】otg_mode不能连接ADB，在设置之中配置之后还是不行！

Chip Platform Rockchip

刷机之后不能连接ADB，在设置之中配置之后还是不行！
AIO-3399J连接PC之后不能通过MTP模式和电脑之间互相传送文件。

在系统之后就可以了！

在设置中，点击connect to pc 就可以连接到pc， 同时传送文件可以点击usb file tranfer就可以进行文件操作

请问您是否拿AIO-3399J刷Android10的固件测试呢过？您使用SDK编译或者预编译固件IMG都可以！

正常情况下，这样配置是可以链接电脑的，但是现在故障就是连接不了！
原因待查！

1、在预编译固件里面没有找到您说到的：connect to pc，只有File Transfer。

2、为了保证效果，在刷预编译固件之前首先擦除了EMMC！

使用贵司的Android10的SDK，请问如何配置系统编译的时候
1、Connect to PC就默认打开呢？？？？
2、开发者默认可以默认打开嘛？3、Default USB configuration默认为File Transfer？
4、系统语言默认为中文

这样可以给我的调试带来方便！
编译之后一刷机，不需要进行这么多配置的步骤了！
