ubuntu 18.04.2 LTS based vivado 2019.1 + petalinux 2019.1
 system-user.dtsi not included in build: -
[a] I have certain dts changes. i included them immediately right after petalinux-config of Uboot and Linux code source paths.
[b] after first time, petalinux-build, i included the dts changes [Even this post does not helphttps://forums.xilinx.com/t5/Embedded-Linux/Device-tree-system-user-dtsi-not-building/td-p/1026183]
[c] i did petalinux -c [device-tree, rootfs, kernel] -x [ mrproper, cleansstate, cleanall, distclean], i injected errors in dts and never was dts included.
what is the correct way to get system-user.dtsi included in the build?
 the directory of all intermediate <project-root>/plnx_workspace/device-tree/device-tree/ dts files is not generated.
i had to use system.dtb and do reverse compilation from dtb to dts and understand final dts changes.
what do i need to do get the intermediate files generated?
 for some reason, the image.ub is always at ~178 MBytes and this image fails with jtag based boot.
if i try to meddle with initramfs settings in petalinux-config -c kernel and multiple petalinux-build -x mrproper, the image.ub size comes down to around 39MBYtes and this boot via jtag.
how can i get the image.ub to ~39MBytes?
