Hi,
I am using snapdragon 410c processor and android 5.1 OS. I want to interface a GSM modem connected on ttyxx port. Currently I am using reference HAL layer provided in Android code. I have compiled it as .so lib and copied it to required location.
The problem is when my .so is called and try to open the ttyxx device, I am getting permission denied error. I have changed init.rc file to point to compile .so library.
I have added following line to ueventd.rc
/dev/ttyxx 0666 radio radio
Is there any qualcomm specific changes that I am missing in code?
The permission of /dev/ttyxx is set to 666.
Regards,
Devang
