[yocto] [rauc] create a rescue image

[jairo]

Hi all,

I want to make a system with a rescue partition.

What is the minimum to make a rescue image? Or how can it be done?

I use a board with a imx6 micro from phytec, and in the meta-yogurt
layer there is a recipe called phytec-initramfs-image.bb that creates
an image or partition with cpio.gz format of 11MB containing rootfs,
can it be used That image as a rescue? If so, how do you copy a cpio
partition in an UBI MTD system?

Thanks in advance
