Hi,

Thank you for your interest in NXP Semiconductor products,

Easiest way is to RM_OLD_IMAGE or clean the bakes so the images are built with your customization,

If this is not desired, you can refer to chapter 4 from Linux Users Guide.

You can flash u-boot directly at the address with the memory map (chapter 4.4.1.4, 4.4.1.5 and 4.6).

For dtb and kernel image, chapter 4.4.1.3.

And for rootfs you should be able to secure copy the generated files or serve them through NFS.

Regards
