We are currently interfacing a sierra wireless(HL8548) module with dragonBoard. so far sierra had given the android RIL integration guide (https://source.sierrawireless.com/~/media/support_downloads/airprime/software/airprime%20-%20android%20ril%20integration%20guide%201.1.ashx).In that we added driver files, Framework and some binary files. My question is, which are the image(.img) we need to create to detect the device. I added boot.img and emmc_appsboot.mbn and in dmesg all the drivers are registered but it’s not detecting. Please help me to resolve the issue.
