Doublecopy swUpdate - IMX8ULPEVK9

[dhruvinrajpura]

I am perfoming swupdate for IMX8ULP-EVK9
For that,
I taken : https://github.com/sbabic/swupdate repo and integrated in our code and I generated .swu file with sw-description and one script that I am attaching here for reference.

With this I am able to perform swupdate successfully and I can change rootfs.ext4 in partition /dev/mmcblk0p2 that you can see in sw-description file.

Now I want to perform swupdate with dualcopy for that what steps/changes I need to do in the above process?

Thanks in Advance.

Thanks @AldoG for response

The document you given I already refered that and in that there is not any explainiation specific to IMX8ULP-EVK9

Like in which partition I need to update copy of image? what needs to be exactly in sw-description file and all ,

I am providing my current partition structure for reference, But I am not able to get that which partiton I need to use to perform dualcopy swupdate?
