Android sensor HAL

26

In the HAL folder:

 [RAS]/device/[vendor name]/[boardname]/libsensors

launch the “mm” command in the HAL folder to build a dynamic library named

sensors.[board name].so. At the end of the process, it can be found in:

 [RAS]/out/target/product/[boardname]/system/lib/hw/

This library can then be added to the existing library, remounting the filesystem and using

the "adb push" command. Follow these steps:

 [RAS]$ adb root

 [RAS]$ adb remount

 [RAS]$ adb push sensors.[boardname].so /system/lib/hw

 [RAS]$ adb shell] stop

 [RAS]$ adb shell] start

Note:

In case of other similar libraries with the same name, use different useful names, like

sensors.[processorname].so.

For reference purposes with the Panda-board, use the example: sensors.omap4.so.

The name of the lib that is built can be chosen and changed by writing the desired name in:

LOCAL_MODULE := sensors.$(TARGET_BOARD_PLATFORM) in the relevant Android.mk

file.
