How to use UUU to burn Image

Hi  NXP

How to use UUU to burn Image?

It is wrong to use the following command

uuu.exe -b emmc Image

Hi

Please try:  uuu -b emmc_all **.wic

The kernel image needs to be burned separately.

Hi

There are uuu example scripts in  demo images, you can use it to download kernel.

uuu_version 1.2.39

# Please Replace below items with actually file names
# @_flash.bin			| boot loader
# @_Image			| kernel image, arm64 is Image, arm32 it is zImage
# @_board.dtb			| board dtb file
# @_initramfs.cpio.gz.uboot	| mfgtool init ramfs
# @_rootfs.tar.zst		| rootfs
# @_uTee.tar			| optee image, put dummy _uTee.tar file here if platform is not MX6/MX7*

# This command will be run when i.MX6/7 i.MX8MM, i.MX8MQ
SDP: boot -f _flash.bin

# This command will be run when ROM support stream mode
# i.MX8QXP, i.MX8QM
SDPS: boot -f _flash.bin

# These commands will be run when use SPL and will be skipped if no spl
# SDPU will be deprecated. please use SDPV instead of SDPU
