Problem solved! It turns out it is the mismatch of ld-linux.so. I referred to this post http://stackoverflow.com/questions/24543474/cross-compiled-gnu-arm-beagleboneblack-from-windows-runtime-error-on-elf, and found my problem was exactly the same: the binary needs /lib/ld-linux.so.3 to run, but that file is missing in the 1.5.1 yocto system on board. Then I copied ld-linux.so.3 file from Yocto toolchain on my pc. Then it works!
