I am trying to connect an HL7648 to an imx8m running Android 9. I am using the latest RIL drivers. I have the modem connecting to the network, getting an ip address. About 1 sec later the modem disconnects.
Here is the logcat -b radio output. Any idea of what could be causing this?
Thanks,
Mark
seems the modem has been reset, do you see any disconnect info in dmesg?

Here is the dmesg, there is a message about the service sierra_config_ip. Could that be it?

I think so, i think it related to SElinux.
Please download ril integration guide.
https://source.sierrawireless.com/resources/airprime/software/android-ril-integration-guide/#sthash.ZZXlFJBG.dpbs
I am running se linux in permissive mode. I am using the instructions from your RIL integration guide.
Here is the code I added to init.rc for the service. Also, the script is present in /vendor/bin
Blockquote
service sierra_config_ip /vendor/bin/init.config.ip
class main
user root
group radio cache inet misc dhcp
capabilities BLOCK_SUSPEND NET_ADMIN NET_RAW
disabled
oneshot
Can you disable the SElinux?
Besides, you can have a look on this and see if it helps.
I belive I have it disabled. It is in permissive mode.
I am also trying to add the sepolicy files from the RIL, but I am having the same issue at this.
https://forum.sierrawireless.com/t/sepolicy-in-android-9-ril/16323
Seems it is not completely disabled.
I am unable to used disabled. I tried to pass it to the kernel, but it does not work.
I am now trying to add the sepolicy file for the service, but I get an build error. The domain name is not a member of the allowed domains.

Do the files in \device\linaro\hikey\sepolicy help?
These are the files causing the build issue. I am currently only using siera_config_ip.te. I copied the file as is and added it to my file_contexts.
Seems you also need to have a look on system/sepolicy/public/domain.te
I don’t see this in the RIL guide. Do you have an example or instructions?
you can see my system/sepolicy/public/domain.te in Android 9.
domain.zip (11.7 KB)
Seems you need to append those neverallow rules.
Same error after updating the domain.te in /system/sepolicy/public/doman.te
Do you have an source of a successful build you can share?

How did you modify domain.te?
I compared the files, and then copied your in the folder. I cleaned my build and rebuilt.
Maybe you can comment out those lines 998 866 839
