No rule to make target 'fsl-imx8mn-evk.dtb', needed by 'u-boot.itb'.

[shinji_tonoshit]

Hi all,

I am creating a QSPI NOR Flash boot image for an i.MX8M nano EVK (8MNANOLPD4-EVK).

I set up the environment referring to "4.5.12 How to build U-Boot and Kernel in standalone environment" in the "i.MX Linux User's Guide."
I am having trouble with an error when I try to create an image.
Please let me know how to solve this problem.

Hi @shinji_tonoshit,

I hope you are doing well

Kindly try with the latest U-boot version lf_v2023.04.

Also, one can refer to section 5.3 Building an image from i.MX Yocto Project User's Guide to build the image using Yocto.

Thanks & Regards,
