I think there’s some UEFI values missing to inform grub on what’s needed to load the driver.
Booting same image on AML-S905X-CC-V2 gives me proper grub menu. (literally swapping sdcards around)
- Using kernel
6.7.0-rc7 - have same behavior with grub packages on debian bookworm and debian sid.
- using uboot aml-a311d-cc-spiflash Dec 14 2023 build
relevant grub voodoo:
function load_video {
if [ x$feature_all_video_module = xy ]; then
insmod all_video
else
insmod efi_gop
insmod efi_uga
insmod ieee1275_fb
insmod vbe
insmod vga
insmod video_bochs
insmod video_cirrus
fi
}
insmod part_gpt
insmod ext2
search --no-floppy --fs-uuid --set=root f4c95414-9778-4eb5-9184-8aa6ed77a22d
if loadfont /usr/share/grub/unicode.pf2 ; then
set gfxmode=auto
load_video
insmod gfxterm
set locale_dir=$prefix/locale
set lang=en_US
insmod gettext
fi
terminal_input gfxterm
terminal_output gfxterm
On AML-A311D-CC_V1.0C
