Hi,
It seems that your processor is built using ARMv6 architecture.
http://pdadb.net/index.php?m=cpu&id=a7227t&c=qualcomm_msm7227t
You can execute following command to get more details about your cpu:
adb shell cat /proc/cpuinfo
OpenCV by default is configured for ARMv7 processors. So you need to
build OpenCV with non-defauilt parameters.
Try to add -DARM_TARGET=armeabi to your cmake command. (You have
remove CMakeCache.txt from your build catalog or make a clean build to
change this param).
