Any manual for build own openwrt use off git?

At first time that you run “build.sh” script, you may pick up your target board for openwrt. then you can use “build.sh” for openwrt build.
./build.sh help

when I put any image to sd card, I receive same log

seems like system hasn’t start image and start default OS. What I do wrong?

Also, when I try use Emma image, my PC can’t see BRI R2 PRO in device tree
