Greetings !
ProcessorĀ  : i.MX8MM
Yocto : 2.7.1 (warrior)
I am trying to crate a "initramfs image" bundling with the "Kernel image".
Below mentioned is the link andĀ  which I am following .
https://www.yoctoproject.org/docs/3.1/dev-manual/dev-manual.html#building-an-initramfs-image
Below is the steps which I followed :
1. Added INITRAMFS_IMAGE_BUNDLE variable to "1" in local.conf
2. Added INITRAMFS_IMAGE = "phytec-initramfs-image" in your local.conf
3. And tried building the image using bitbake.
But when I am compiling the image, I am getting the following mentioned "Circular dependency error". Kindly Requesting solution/suggestions for the same .
initramfs images are a bit special. it should say

IMAGE_FSTYPES = "${INITRAMFS_FSTYPES}"

and perhaps then you should be able to build your full image which is not this image but this image will be bundled in the final full image
