Porting openEuler system to Allwinner A401

Can the OpenEuler rootfs be integrated into the Allwinner Linux SDK?

And can the kernel configuration be modified and OpenEuler patches be incorporated?

If the Allwinner Linux kernel version matches the OpenEuler kernel version, is this approach feasible?

Is Allwinner’s Linux SDK built using Yocto?

I’m not quite clear on how exactly to integrate the OpenEuler rootfs.

The rootfs involves version dependencies among various packages. Merging two rootfs together might lead to some issues. It’s not recommended to do so.

If the kernel versions are consistent, the problems should be minimal.

If Allwinner’s Linux kernel incorporates OpenEuler’s modifications and gains OpenEuler’s features, can it run OpenEuler’s rootfs, including systemd and the C library?

As long as the kernel version matches, and with openEuler’s modifications applied, it should be possible to run openEuler’s rootfs, since the two are essentially very similar—there are only minor differences in kernel patches.

How do I apply openEuler patches to the Linux kernel? Where can I download these patches?
