Hi there,
I am trying to implement the MC7455 into Android 5.1.1 with Linux Kernel 3.4.0-g039ba5c-00051-gdd8f2f16-dirty, using the AndroidRIL_V5.1.9_ARM_5.1_V1.0_bin.
I have a problem getting an IP address for the wwan0 interface.
I started by integrating the bins, librarys and drivers, which are present at the android-board.

The drivers seem to work quite well, as I get the devices and by analysing the kernel messages.

I can see the argument, that there is no carrier for the dhcp, am I right?
I integrated the code for the phone status to display the IMEI etc, which can be seen in android:
I tried two different SIM Cards but this did not help at all. Then I outcommented the line to start the ril deamon in init.rc, so that I could switch it on manually by “start ril-daemon-qmi” for debugging purpuse. I made a log with
$ (adb logcat -v time -b main -s dhcpcd & adb logcat -v time -b radio) | tee /tmp/logForSierra
logForSierra.txt (612.1 KB)
where I boot the system and then start the ril deamon manually.
Interestingly is, that the RIL gets an ip address and the right dns addresses from vodafone (germany)

and then monitor the actions on the interface and trying to logcat the dhcp at the same time, to understand the connection between them.

As far as my understanding goes, I am missing a carrier. How do solve that? I am running out of ideas. Does anyone have a smiliar problem, a clue or an idea, what I could try next? Any help would be highly apreciated!
