title: flashing yocto image to raspberrypi cm3 eMMC

  In the deploy/images/raspberrypi-cm3 directory a don't have a .img file that would be flashed and also how can i knew if my image will boot directly when starting.

  <p>Thank youf or the answer.
  As i understanded, the mount command line is to create a disk image and makes it readable by the system. So after copying all image directory to it and unmounted it, what would i have in the 'if' option when i will flash my image with 'dd if=/home/user/deploy/images/raspberry-cm3 of=/dev/mmcblk1 '.</p>
  
  <p>Also when a tried to mount the disk image 'sudo mount -o loop raspberry-cm3.img /media/raspberry-cm3/'.</p>
  
  <p>error:mount: mount point /media/raspberry-cm3/ does not exist.</p>
  
  <p>Could you please help me with that ?</p>
