问题一：
重新编译Qt5.6.1后移植到am335x板子后，跑一个空的Qt界面程序CPU占有率到达96%以上，导致很卡，求教这是什么问题导致，是不是我配置的问题？具体配置如下：
qmake.conf：
#
# qmake configuration for building with arm-linux-gnueabi-g++
#
MAKEFILE_GENERATOR = UNIX
CONFIG += incremental
QMAKE_INCREMENTAL_STYLE = sublib
include(../common/linux.conf)
include(../common/gcc-base-unix.conf)
include(../common/g++-unix.conf)
QT_QPA_DEFAULT_PLATFORM = linuxfb
QMAKE_CFLAGS_RELEASE += -O2 -march=armv7-a
QMAKE_CXXFLAGS_RELEASE += -O2 -march=armv7-a
QMAKE_INCDIR += /home/pc335/tslib1.4/include
QMAKE_LIBDIR += /home/pc335/tslib1.4/lib
# modifications to g++.conf
QMAKE_CC =arm-linux-gnueabihf-gcc
QMAKE_CXX = arm-linux-gnueabihf-g++
QMAKE_LINK = arm-linux-gnueabihf-g++
QMAKE_LINK_SHLIB =arm-linux-gnueabihf-g++
# modifications to linux.conf
QMAKE_AR =arm-linux-gnueabihf-ar cqs
QMAKE_OBJCOPY = arm-linux-gnueabihf-objcopy
QMAKE_NM = arm-linux-gnueabihf-nm -P
QMAKE_STRIP =arm-linux-gnueabihf-strip
load(qt_config)
configure配置：
./configure -prefix /home/am335x/hustQt5.6.1 -opensource -confirm-license -release -shared -xplatform linux-arm-hust -optimized-qmake -pch -qt-sql-sqlite -qt-libjpeg -qt-zlib -qt-libpng -qt-freetype -tslib -no-opengl -no-sse2 -no-openssl -no-nis -no-cups -no-glib -no-dbus -no-xcb -no-eglfs -no-xcursor -no-xfixes -no-xrandr -no-xrender -no-separate-debug-info -no-iconv -make libs -make examples -make tools -nomake tests -skip qt3d -skip qtcanvas3d -skip qtdoc -skip qtwayland -I/home/am335x/tslib1.4/include -L/home/am335x/tslib1.4/lib
问题二：
ti-processor-sdk-linux-rt-am335x-evm-02或者ti-processor-sdk-linux-rt-am335x-evm-03在am3352上使用linuxFb跑Qt5程序，触摸屏怎么校正？ weston启动不了，不能用weston-calibrator校正，求教如何解决这个问题
