Hi, I am new to Yocto Project and learning to develop software on Atmel
SAMA5D3 Xplained board, on which Yocto 1.5.1 is pre-built. I followed the
instructions and got the 1.6.1 toolchain

I can compile the simple HelloWorld program and binary file is made. Then I
copied the binary file

into board and tried to run it. However, when I changed to the file located
directory and type

"./Hello", it returned "sh: ./Hello: No such file or directory". Then I
tried "sh Hello", it gave

me "Hello: Hello: cannot execute binary file ". If I type "file Hello", it
gives "Hello: ELF 32-bit
LSB executable, ARM, EABI5 version 1 (SYSV), dynamically linked (uses
shared libs), for GNU/Linux 2.6.16,
BuildID[sha1]=9933a2d2ce212099c5f9902a8e612c1423e136da, not stripped". I
googled and someone

said the problem may be the toolchain. Then I tried 1.3, 1.5.1 toolchain for
arm, but still same

error. Could you please help me about this problem?

i suspect this is an armv7 soft-float vs hard-float mismatch. Either
your prebuilt OE system is configured with soft-float and the
toolchain you use compiled for hard-float by default, or the other way
around. can you check how you've compile HelloWolrd and check the
other ABI?
