I am using ls1012aFRDM development board. I used following method to add my application executable file in rootfs


    1. rename your RAM disk image to rootfs.ext2.gz.uboot
    2. sudo apt-get install u-boot-tools
    3.dd if=rootfs.ext2.gz.uboot of=rootfs.ext2.gz bs=64 skip=1
    4. gunzip rootfs.ext2.gz
    5. mkdir /mnt/iso_1
    6. sudo mount -oloop rootfs.ext2 /mnt/iso_1
    7. Now, I copped files into appropriate location under “./mnt/iso_1” directory.
    8. sudo umount /mnt/iso_1
    9. gzip -9 rootfs.ext2
    10 mkimage -A arm64 -O linux -T ramdisk -C gzip -n 'rootfs.ext2.gz.uboot' -d rootfs.ext2.gz rootfs.ext2.gz.uboot


My questions are
1. Is the above method is correct.
2. How to create kernel.itb with this file system.
3. While create mkimage, What should be the Load Address and Entry Point address for rootfs and kernel image   
4. I also tried files/merge method, but it gives following error after performing bitbake fsl-image-core
