求助：rk3399 adb不能使用

Chip Platform Rockchip
1

我手头有块AIO-3399C（AI）板子，目前按照 http://wiki.t-firefly.com/AIO-3399C/buildroot_compile.html
Buildroot部分的指导，编译出的linux固件不能使用adb调试，请问各位大神是什么原因？
1.PC连接板子的typeC时，串口打印如下：
[root@rk3399:/]# [ 20.493897] phy phy-ff770000.syscon:usb2-phy@e450.7: charger = USB_SDP_CHARGER
2.PC使用公对公usb连接板子的usb3.0时，串口没有任何输出

PC端lsusb也是没有发现相关设备。

感谢firefly, 我得到了firefly很好的支持。
打上以上这个patch → kernel/arch/arm64/boot/dts/rockchip/rk3399-firefly-aioc-ai.dts
typec口就可以用作otg功能了，adb调试也就正常了

确保一下 device/rockchip/ .BoardConfig.mk 的 RK_KERNEL_DTS=rk3399-firefly-aioc-ai 是否正确 重新编译，升级

PS：数据线接typec
