You need to start to read through the various sources to figure out for
yourself what is going on!
Starting from the bottom, in U-Boot 2017.03 all of the command sources
are in the âcmdâ directory. The âubi â¦â command are all in ubi.c.
Reading cmd/Makefile shows that file gets added into the build if
CONFIG_CMD_UBI is enabled.
The next place to look is whether or not that is set in your defconfig
for U-Boot or overwritten somewhere in a recipe in your Yocto build
