Package: grub-efi-arm64
Version: 2.14-2
Severity: normal
X-Debbugs-Cc: mh+debian-bugs at zugschlus.de
Hi,
I'm running Debian unstable on a Raspberry PI 4. The firmwware loads
u-boot, u-boot loads grub-efi-arm64, grub-efi-arm64 drops me on a grub
rescue shell with "error: symbol `grub_memcpy' not found.". Going back
to grub-efi 2.12-9+deb13u1 from trixie works without other changes to
the system.
The information given below originates from the system after doing the
downgrade.
Boot log on bottom.
Greetings
Marc
