Does Yocto / OE build u-boot image for u-boot configs in #define CONFIG_EXTRA_ENV_SETTINGS? #define



I created recipes-bsp and an appended file u-boot-imx_2018.03.bbappend
to build a customized imx6ullevk image, I added my configures in
#define CONFIG_EXTRA_ENV_SETTINGS in mx6ullevk.h, it built the
u-boot-ram.imx and u-boot-nand.imx, I tried uuu to store
u-boot-ram.imx to the =customized imx6ullevk board, all settings in
CONFIG_EXTRA_ENV_SETTINGS were lost, set nothing in u-boot. It did not
seem that Yocto / OE built the u-boot correctly and properly, what I
could be missing?

Thank you.

Kind regards,
