How to sign image in yocto, I want to use secure boot

[ljm3721]

Hello
How to sign image in yocto, I want to use secure boot.

This is the firmware I compiled using yocto and the firmware I burned using the uuu tool.

core-image-base-imx6ull14x14evk.wic.bz2

Can you help me

You can find references for recipes and configs for secure boot from Yocto build. But so far we've not provided such support for yocto.

Recommend to refer the link (uboot-imx/doc/imx/habv4/guides/mx6_mx7_secure_boot.txt at lf_v2022.04 · nxp-imx/uboot-imx · GitHub) for secure boot.

Best regards

Harvey
