Hi! Trying http://download.opensuse.org/ports/aarch64/tumbleweed/appliances/openSUSE-Mi... on an rpi400 (after adding necessary boot files). The u-boot there does not seem to support writing UEFI variables. That's rather crucial to systemd-boot to eg. specify what to boot next. Is that a generally missing feature of u-boot, or is it possible somehow to make u-boot store uefi variables eg in the efi partition? cu Ludwig -- (o_ Ludwig Nussel //\ V_/_ http://www.suse.com/ SUSE Software Solutions Germany GmbH; GF: Ivo Totev, Andrew McDonald, Werner Knoblich; HRB 36809 (AG Nürnberg)

RPi’s don’t have where to store these variables, like no separate flash or so. Using main uSD as storage for this variables is hazardous operation, think for concurrent access from UEFI services and OS itself. Regards, Ivan
Thanks for sharing more information! The fact that Raspberry Pi does not have a separate storage area for UEFI variables but only uses the main microSD card, https://1v1lolonline.io/, and using SD cards for multiple purposes can create risks such as conflicts or concurrent access. This is an important note when configuring the boot system and managing UEFI variables on these devices. If you have any further questions or need support, please feel free to share!
