Hello Pankaj,

  Try below mentioned steps, Hope it helps you, (there my image was"core-image-base-raspberrypi3.rpi-sdimg"  replace it by your image )


plug sd card to pc then

$: lsblk
$: sudo umount /dev/sdb*

$: sudo dd if=tmp/deploy/images/raspberrypi3/core-image-base-raspberrypi3.rpi-sdimg of=/dev/sdb bs=4M

  >> This task will take some time and at the end we will get the output something similar(not exact it depends on build files) to below :

        46+0 records in
46+0 records out
192937984 bytes (193 MB, 184 MiB) copied, 10.2155 s, 18.9 MB/s

Thanks!
