buildroot-2015.02에서는 tslib가 single point 터치만을 지원하고 있습니다.
이것을 multiple point 터치를 지원하게 변경하는 방법입니다.
buildroot-2015.02 디렉토리에서 tslib package 관련 파일들을 수정합니다.
buildroot-2015.02$ cd package/tslib/
tslib$ sudo cp -a Config.in Config.in.org
tslib$ sudo cp -a tslib.mk tslib.mk.org
--------------------------------------------------------------------------
tslib$ sudo vi Config.in
config BR2_PACKAGE_TSLIB
bool "tslib"
depends on !BR2_STATIC_LIBS # dlopen
help
Tslib is an abstraction layer for touchscreen panel events.

위와 같이 수정하였으면 make 옵션에서 multiple point 옵션을 선택하고, 빌드합니다.
