IIRC, grub2.04 requires a recent armv7 kernel because it needs a proper EFI boot.
So, Leap 15.1 will probably not boot with grub2.04 from Tumbleweed. So, I would suggest to
use grub2.02 from Leap 15.1, if you want to boot multiple distros. Then, os-prober should
be able to detect other OS.
If your plan is to use Tumbleweed and Leap 15.2, grub2.04 will be fine.

Subject: [opensuse-arm] Multiple distro system
I have been running a cubox-i with Leap since several years, booting it from an
eSATA HD (at the moment I have a Tumbleweed SD in my cubox-i with the only
task to launch uBoot that, in turn launches GRUB on the HD).
My HD contains an EFI primary partition, a / primary partition, an extended
partition (that in turn contains a SWAP logical partition, an empty ext4 logical
partition and some spare space), and finally a primary /home partition.
I would like to install (onto logical partitions) other distros tailored for cubox-i
by side with Leap, which should remain the default OS.
Can you suggest the best approach to accomplish that?
Thank you in advance.
