I have selected * for all apps, protocol........ , but they are not packed into .img, despite I have selected enough selected big enough root and boot file size. I have 8G emmc.
"All"? Meaning every package that is possible to build for OpenWrt? You can't, there are conflicts and it won't fit on virtually anything but an x86 with a hard drive.
Without the buildbot, it's difficult to even successfully build all packages. If you were able to, one approach would be a full repo on the device's disk from which you could install from.
