Thanks @pbrobinson or your reply.
We have made a SD card using arm-image-installer utility and after that we have changed the u-boot and kernel image (upstream kernel with our customised patches for our hardware). We parsed the commandline argument
ostree=/ostree/boot.0/fedora-iot/5664fcf7ba61ad3632b58faf71ec0965c413be4b6a63754015d1cba5b09079db/0
init=/ostree/deploy/fedora-iot/deploy/23010389d9eb42baedcd764a2aca8afa2a5958e61477359526a3ea998f0c4d2d.0/usr/lib/ostree/ostree-prepare-root"
Our kernel got stuck and throws below error.
[ 3.717428] Run /ostree/deploy/fedora-iot/deploy/23010389d9eb42baedcd764a2aca8afa2a5958e61477359526a3ea998f0c4d2d.0/usr/lib/ostree/ostree-prepare-root as init process
