No valid device tree binary found - please append one to U-Boot binary, use u-b>

hello,

I did solve the issue changing source file from following link, had a doubt why these changes are not done in uboot source yet, or i am doing something wrong here(as like dirty workaround).

Hello,

I dont think problem is with fit image generation, problem is with uboot binany. I am using same recepi as the link you shared in my yocto config.

Can you post the local.conf file?

Does the uboot compile? If there was no DT in uboot it should error when running dtc in uboot.
