Buildroot for uboot+kernel+rfs

ts1234 — Tue, 22 Dec 2020 09:09:47 GMT

How do I use LSDK's (flexbuild_lsdk2012.tgz) buildroot package for building uboot+kernel+rfs images.

Currently buildroot is only used for rootfs (rfs). Uboot and Kernel are built separately.

I am looking for the changes required for moving the kernel+uboot build from flex-builder script to buildroot. I also want to create the install images as well through buildroot.

Can I use openil instead of the LSDK?

What is the relationship between OpenIL Linux and the LSDK Linux? Which one should be preferred for LS1043A or LS1023A?

You could generate firmware image with the following command in LSDK.

$ flex-builder -i mkfw -m ls1043ardb -b nor

The firmware image includes atf, Kernel image, dtb and rootfs filesystem.

You could use openil instead of LSDK.

Linux Kernel in Openil 1.9 or 1.10 is based on Linux Kernel in LSDK 20.04.

The applications in Openil are different from LSDK. Both LSDK and Openil support LS1043.
