IMX6SL oreo ril porting

[chandrasekhar_a]

hi,

We are successfully ported the RIL in KITKAT 4.4.3 where are we are facing the problem in Oreo RIL porting.

We have received the latest RIL libraries from the vendor and ported in the same way as mentioned in there porting guide.

but we are unable to find the network settings and the SIM related setting in the GUI. We have attached the

"$logcat -b radio"  log file to this. We are able to that modem is talking the RIL as AT commands are executing and we are getting the response from the modem.

Is there any modifications we have to do on the BSP to get the network related options in the GUI.

If it is true then tell us the modifications to get the network related settings in the IMX6SL Oreo.

Thanks in advance.

Regards,

A.Chandrasekhar

Hi All,

I have done the same experiment on imx6dl and Android Oreo 8.0. basically they have done it WiFi Only device in BSP which has to be changed to mobile_network enabled device. following files has to be changed.

1. device/fsl/imx6/imx6.mk

-    ro.radio.noril=yes
+   ro.radio.noril=false --> make it false.

2. sabresd_6dq/overlay/frameworks/base/core/res/res/values/config.xml --> used to Override the superset config.xml present in Android Frameworks, so comment out few lines from this file.

This changes keeps the default Android frameworks settings as it is which enables the mobile_network support.
