Configure Yocto Output zip extension type

I previously had yocto images being generated with .gz zip types

core-image-imx8mn-var-som-20240426072843.rootfs.tar.gz
core-image-imx8mn-var-som-20240426070451.rootfs.wic.gz

but ever since I updated my yocto flavour I am now producing .zst zip types for the image output. Is there a way to configure the zip type that is used?

core-image-imx8mn-var-som-20240426072843.rootfs.tar.zst
core-image-imx8mn-var-som-20240426072843.rootfs.wic.zst

My Yocto Flavor is Mickledore 4.2

Solution

  • Add the following line in local.conf to generate wic.gz compressed image.

    IMAGE_FSTYPES += " wic.gz"

    You can also add other image types that you want to build here like wic.bz2, wic, ext4 etc
