creating Initramfs in Yocto

1
votes

I wanted to create initramfs in yocto. Therefore I created a custom recipe, added following lines; require recipes-core/images/core-image-minimal.bb IMAGE_FSTYPES = "${INITRAMFS_FSTYPES}"

It built successfully. I am not sure if all works properly. I guess kernel and u-boot also need to be configured.

My question is, does yocto configure kernel and u-boot automatically after seeing IMAGE_FSTYPES = "${INITRAMFS_FSTYPES}" or I should configure them myself?

Thank you. Best regards

creating a new image-initramfs.bb image, and adding

include original-image.bb



IMAGE_FSTYPES = "${INITRAMFS_FSTYPES}"

PACKAGE_INSTALL = "${IMAGE_INSTALL}"

And then in conf/local.conf

INITRAMFS_IMAGE = "image-initramfs"   ### < image-initramfs is the .bb file above

INITRAMFS_IMAGE_BUNDLE = "1"
