Platform: RK3399
OS: Android 7.1
Kernel: v4.4.126
需求
- 熱插拔
- 默認打開 UVC 功能
調試步驟
在移遠提供的 ql-ril.conf 中添加
- 添加
Sim_Hot_Plugging=2
- 添加
At_Cmds_For_Customer_Initialize=AT+QCFG="usbcfg",0x2C7C,0x0125,1,1,1,1,1,0,1;AT+QPCMV=1,2
如果不需要打開
At_Cmds_For_Customer_Initialize=AT+QCFG="usbcfg",0x2C7C,0x0125,1,1,1,1,1,0,0;AT+QPCMV=0
ql-ril.conf 中的內容會在開機的時候由移遠提供的 ril 庫調用．寫入到 EC20 的 NV 中．
即，如果沒有其他的 AT 指令將其覆蓋，掉電後也不會丟失．
