No valid device tree binary found - please append one to U-Boot binary, use u-b>
initcall sequence 04053ff0 failed at call 0404a4d4 (err=-1)
### ERROR ### Please RESET the board ###

May i know what i must have wrong during the process.

Thanks & Regards,

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.

Thanks & Regards,

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.

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).
