I am trying to integrate OPTEE with one of my custom Yocto distro. I have an STM32MP157f -dk2 eval board. I have added optee in machine conf and disto conf files. It build successfully but the raw image on sd card has uboot failure. Need help

[KMark.1]

I followed some of the steps to integrate OPTEE with Yocto builds as below.

meta-bsp-stm32mp1/conf/machine/stm32mp157f.conf

MACHINE_FEATURES +="optee"

BOOTSCHEME_LABELS += "optee"

meta-product-stm32mp157x-dk2/conf/distro/pxred-stm32mp1-dk2.conf - distro changes

DISTRO_FEATURES_append = " px-red-kinit-e2fsprogs \

                            optee \ "

The following is the boot message I get on terminal
