User app not packaged in SD card boot image

Hello,

I am following UG1144 and 1157 documentation on petalinux from Xilinx for ultrazed board. i have Vivado 2017.3 and petalinux 2017.3 installed in Unbuntu 16.04 64 bit machine.

the issue is

when i create the package and load the - BOOT.bin and image.ub file on the SD card and load it on the board, i am not able to see myapp inside /usr/bin folder .. but if i look into the rootfs.tar.gz file ?(which is a tarball or the filesystem, i can see the myapp in /usr/bin path ) ? not sure what is wrong here .. is board getting booted correctly ?

i have tried to explain my issue in detail here:

Hello,
So i was able to find that this is a kown issue with Xilinx : https://www.xilinx.com/support/answers/69780.html
But when i applied this fix .. i am now getting a different error :
PLL: shutdown
Found that this was another issue : https://www.xilinx.com/support/answers/69764.html
and applied its given fix in Vivado and regenerated the bitstream and imported it the project but then got this error:
VFS: cannot open root device "mmcblk0p2" or unknown-block(179,2) : error -6
Kernel panic VFS : Unable to mount root fs on unknown-block(179,2)
following what was discussed here : https://forums.xilinx.com/t5/Embedded-Development-Tools/Beginners-problems-with-Ultrazed-eg/td-p/800802
I tried updating the system-user.dtsi file under : petalinux_prj/proj-spec/meta-user/recipes-bsp/device-tree/files/system-user.dtsi,
but now i keep getting error :
* Unable to read file system.dtb *
Also i was able to generate the project from avnet scripts on github... li tried to copy the same system-user.dtsi file in my folder and yocto started to give build errors....
