agl-sota u-boot raspberrypi3 - Card did not respond to voltage select! Device 0: unknown device

Question

I am building an automotive-grade-linux demo image using yocto for raspberrypi3. I am adding a layer agl-sota for OTA feature. This is where my u-boot breaks. While booting up according to defconfig CONFIG_ENV_EXT4_DEVICE_AND_PART="0:1" u-boot takes mmc0 which is sd card that can be verified through 'mmc info' and partition 1. Yet it shows:

What configuration issue is disallowing u-boot to boot the kernel.? I am using raspberrypi imager for flashing the wic.xz image.
