I have developed a sensor device driver for android kitkat 4.4.2 (linaro release 14.05 for pandaboard source code) using the cross compiler "arm-eabi-" and ARM archetecture. Can i compile the same driver for Android 4.4.2 64 bit and 32 bit both? is the default android available on linaro 14.05 release for pandaboard website
is 32 bit or 64 bit?
And which cross compiler is best to convert a running linux device driver from 32 bit to 64 bit. or can make a driver that will be compatible to both 64 bit and 32 bit
android os.
Is linaro provide any release for64 bit AOSP ?
