I’m currently working for a project that uses Gigabyte Brix devices (the GB-BLCE-4000C to be exact, see https://www.gigabyte.com/Mini-PcBarebone/GB-BLCE-4000C-rev-10 ) in combination with Ubuntu Server 19.04. We’ve equipped these systems with 4GB, a 120 GB SSD and a USB 4G dongle for connectivity. T…

[image] PJK: why doesn’t the mender-convert generated image boot through to the active rootfs by itself, without me having to do the trick via the UEFI shell? It might be a setting in the UEFI firmware, that the Ubuntu directory is prioritized before the BOOT folder. Does it help to delete th…

[image] kacf: It might be a setting in the UEFI firmware, that the Ubuntu directory is prioritized before the BOOT folder. Does it help to delete the former from the 1st partition? Ok, removing the Ubuntu subdirectory has resolved the boot to Grub issue. The image now boots through to the cor…

I’ve been doing some experiments with Grub and booting with the 4G USB stick inserted. I see that the internal SSD has been shifted to (hd2) because the stick introduced both an (hd0) and a (hd1) drive in the mix, with (hd0) being presented as a drive with ISO9660 filesystem (basically it imitates a…

Hi @PJK I don’t think we deliberately remove features from the build-time configuration but rather just use the defaults. I’ve been working on a more robust fix for this where grub actually provides a variable specifically for the device grub itself was launched from. We should then be able to bui…

Hi @drewmoseley . I’ve added the regexp command to the grub.cfg script used by mender and I get the message “unknown command” when it tries to execute it. I’ve noticed that other important grub2 commands (like help) also give this message when I try them out on the command line. The list of known com…

This is probably the appropriate location, mendersoftware/mender-convert-integration-scripts/blob/master/grub-efi/docker-create-grub-efi-binaries #!/bin/sh set -e GRUB_VERSION=${GRUB_VERSION:-2.02} GRUB_MODULES="boot linux ext2 fat serial part_msdos part_gpt normal \ efi_go…

@mirzak : Thanks for the links. From the looks of it it seems that the Grub2 used by mender is somewhat slimmed down. I’ll see if I can create a less slim version and integrate that in our current boot image.

@mirzak I’ve tried to change the script to include the required regexp module in the list of GRUB_MODULES, but the resulting BOOTX64.EFI file that created led to a halted Grub2 on startup (just shows a line cursor and nothing happens). Are there any dependent modules that need to be included beside…

Ok, I’ve built the default Grub2 and that one also halts with a bar cursor, so something is wrong in the build scripts (or something extra needs to be done). I’ve also build an x86_64 Grub2 from the sources available at the GNU website and following instructions available on the internet I managed t…

I recently built and used GRUB successfully on ARM, using these build commands: ./bootstrap ./configure --with-platform=efi --host=arm-linux-gnueabihf make grub-mkimage -p /efi/boot -d grub-core -o bootarm.efi -O arm-efi <MODULES> As mentioned, this is ARM, but you can just change or remove the “a…
