LED didn't work

I used the Arduino IDE burning the code in the Galileo, but it did't work.

The code is from the Blink of examples.

The I tried to burn it, but It shows information.

#mv the downloaded file to /sketch/sketch.elf

Moving downloaded file to /sketch/sketch.elf on target

target_download_name="${host_file_name##*/}"

echo "Moving downloaded file to /sketch/sketch.elf on target"

"$fixed_path/lsz" --escape -c "mv $target_download_name /sketch/sketch.elf; chmod +x /sketch/sketch.elf" < $tty_port_id > $tty_port_id

Transfer complete

I didn't know how to do, please help me.

Thanks!
