RIL/telephony phone features not working on imx8mq-evk Android-Pie

[muhammadawais]

 I am trying to attach a USB modem with " NXP i.MX 8MQuad Evaluation Kit (EVK)" . I have added/updated my rild service in init.rc and my rild service is able to communicate with the modem at ttyACM0 port and receive AT commands responses.
To enable phone features I have done following configurations in AOSP .

in file  [ANDROID_SOURCE]/device/fsl/imx8m/ProductConfigCommon.mk

PRODUCT_PROPERTY_OVERRIDES += \  ro.radio.noril=no     (changes from yes to no)

in file [ANDROID_SOURCE]/device/fsl/imx8m/evk_8mq/overlay/frameworks/base/core/res/res/values/config.xml

changed voice capability to true.

 My rild service is running fine but there is no API from RIL of android side and my phone feature is not working. On UI its says No Sim Card.

some maybe useful radio logs are following

Please help me on this. Am I missing some framework configuration or packages? Thanks

Hello,

any updates on this issue?

I am facing the same on Android 11 as well.

maybe you need to add radio for RIL:

add these code to device/fsl/imx8m/evk_8mq/manifest.xml :

<hal format="hidl">
<name>android.hardware.radio</name>
<transport>hwbinder</transport>
<version>1.1</version>
<interface>
<name>IRadio</name>
<instance>slot1</instance>
</interface>
<interface>
<name>ISap</name>
<instance>slot1</instance>
</interface>
</hal>
<hal format="hidl">
<name>android.hardware.radio.deprecated</name>
<transport>hwbinder</transport>
<version>1.0</version>
<interface>
<name>IOemHook</name>
<instance>slot1</instance>
</interface>
</hal>

Yes, This Helped Me. RIL was stopping in the beginning only without these permissions. After adding these lines. RIL progressed and got NW registered.

Hello Muhammad Awais,

I would recommend that you look for mode information on the Android Developer forums regarding the RIL service on the AOSP.
