[Kirkstone] Raspberry Pi CM3 Uboot bootup issue

Hi All,

I have been trying to build a core-image-base image for my Raspberry Pi CM3. The Yocto branch I am trying to build on is Kirkstone, the Kernel version is 5.15.34 and the uboot version is 2022.1. I observed that when I built my image without uboot(Without RPI_USE_U_BOOT = "1"), the board is able to successfully boot and show console debugs(enable_uart=1). But when I added Uboot in my build(RPI_USE_U_BOOT = "1"), the board showed no response on the console and even the activity led was OFF. I am a building using kas and the yaml is as below.

Do I need to make any specific changes for it to work on CM3? Thanks in advance
