Initramfs with OpenSBI for a RISCV SoC

Initramfs with OpenSBI for a RISCV SoC

Hi,

i pulled openembedded-core, meta-openembedded, meta-riscv layers
In build/local/auto.conf, added INITRAMFS_IMAGE = "core-image-minimal-initramfs" and INITRAMFS_IMAGE_BUNDLE = "1"
I created core-image-minimal-initramfs.bbappend with adding riscv to COMPATIBLE_HOST

trying to build with "bitbake riscv-initramfs-image"

(without adding INITRAMFS_IMAGE in build/local/auto.conf, able to get successfully the kernel Image files, dtbs, riscv-initramfs-image-mach1-???????.rootfs.cpio.gz, except initramfs is NOT bundled along with the kernel Image which i want)

getting the following circular dependency error

Identifying dependency loops (this may take a short while)...

ERROR:

you can try to build just the kernel which should build the initramfs
image too or build any other image than 'core-image-minimal-initramfs.

bitbake core-image-minimal

e.g.

I found the issue.
The issue was that i have added "opensbi" using EXTRA_IMAGEDEPENDS through conf/machine/<machine>.conf file and that has made "opensbi" as dependency for initramfs image also.
This has created the circular dependency.

I added a EXTRA_IMAGEDEPENDS = "" to the core-image-minimal-initramfs.bb

This fixed the circular dependency issue.

good, I think this could be a patch for
core-image-minimal-initramfs.bb that you can submit to oe-core ml.
Since we use opensbi in qemu machines its highly likely to be copied
into BSPs
would you mind submitting such a patch?

Khem,

Thanks. I have submitted the patch https://lists.openembedded.org/g/openembedded-core/message/150584
