Your script expects "grub>".
I have been using the GRUB installed by Debian.
I guess you expect the one from:
http://download.opensuse.org/ports/armv7hl/distribution/leap/42.2/repo/oss/suse/armv7hl/grub2-arm-efi-2.02~beta2-87.1.armv7hl.rpm
I suggest that both prompts ("grub>", "grub rescue>") should be
permissible.
grub rescue means that grub is in emergency mode because it could not
find its modules. This is definitely not ok :). It usually indicates a
device path issue.
In your case, I'm slightly puzzled why grub would append ,msdos2 to a
netboot path. But it definitely looks wrong, as it could not find the
real config file (which should also reside at the tftp location).
The Suse copy shows only 'grub>' though I have no grub.cfg on the tftp
server nor did I install any modules.
It probably already embeds the "normal" module then.
On Debian grubarm.efi is only generated when you run grub-install and in
the generation process it adds the the relevant partition (msdos2). The
Debian package itself contains no file with an .efi extension.
Building upstream GRUB does not generate any *.efi file either. Instead
it behaves like Debian generating the *.efi file when installing GRUB on
the user chosen partition.
I wonder if it were not preferable to have the build recipe for GRUB and
the binaries on a denx.de server. Do you know the path to the Suse GRUB
build recipe?
The prebuilt grub.efi is mostly there to help with secure boot. It
allows the distro to ship a self-contained grub binary that does not
require any external modules. The build recipe for that is here:
https://build.opensuse.org/package/view_file/Base:System/grub2/grub2.spec?expand=1
Just search for "grub.efi" in the file to see the command.
Alex
