Hello,
Why bootmenu command is not used atm? Are there any reasons?
You mean ansi bootmenu? If yes, ac100 community member tried to enable
it for our board,
but extlinux.conf was proposed as better solution, here is link
http://patchwork.ozlabs.org/patch/450122/
I tried to use extlinux.conf with openSUSE on Chromebook Snow,
because its support already enabled there, and it work flawlessly and
very flexible,
take a look at README.distro in u-boot repo, also as it is same as pxe
config file kiwi probably already have
support for it.
Here is example of my test extlinux.conf:
TIMEOUT 1000
ONTIMEOUT localboot
DEFAULT default
MENU TITLE Boot menu
PROMPT 0
LABEL default
MENU LABEL Default
LINUX /boot/zImage
FDT /boot/dtb/exynos5250-snow.dtb
INITRD /boot/initrd
APPEND root=/dev/disk/by-id/mmc-SL08G_0x01978580-part3

LOCALBOOT 1
Nice. I cannot understand is it uboot who runs extlinux or just support
of extlinux configuration file syntax inside uboot?
I think nobody worked on it until now.
Oh, I see.
But first I am going to introduce additional env variable to simplify
selection of the kernel version from u-boot command line.
After then, I would highly want to have fallback possibility like the
following:
https://www.gnu.org/software/grub/manual/legacy/Booting-fallback-systems.html
which can be implemented using u-boot uEnv.txt file
