Android RIL with HL8548

Hi All

I have a problem when integrating HL8548 with android 4.4. I copied all file (Device driver ,Android RIL,framework) to Android device but It can’t connect to network from module.
So could you give me any idea or advice for this problem.

Normally network interface in RIL available in USB0/1. can you check it’s there in the /dev entry?
If it’s then check init.dhcpcd file if there is instruction of dhcpcd on usb0/1.
