You can download the uuu document and tools from: Release Release uuu_1.5.165 · nxp-imx/mfgtools · GitHub

or refer to <4.2 Universal update utility> in Linux User guide. https://www.nxp.com/docs/en/user-guide/IMX_LINUX_USERS_GUIDE.pdf

Command for your reference:  uuu -b emmc_all <bootloader> <rootfs.wic.zst/*> 

rootfs: imx-image-full-imx6qpsabresd-20240108113535.rootfs.wic.zst

I can find nothing about dtb version with command  uuu -b emmc_all <bootloader> <rootfs.wic.zst/*> .

which dtb is used?

[Harvey021]

I don't have the Yocto one but should be one as imx6qp-sabresd.dtb by default. 

You can try pri fdtfile in uboot console to confirm it.
