Hi,
I tried to boot latest debian and fedora rootfs via distro boot and getting errors. I have tried to run just one command and it is failing.
ZynqMP> bootefi bootmgr ${fdtcontroladdr} BootOrder not defined EFI boot manager: Cannot load any image
How to define BootOrder?
Thanks, Michal
# Booting via boot manager
U-Boot currently has no runtime support for variables. But Linaro is working on it. So update-grub cannot set the variables for you.
Who from Linaro is working on it? Akashi?
You can use the efidebug command to prepare for booting via the boot manager:
=> efidebug boot add 0001 Debian mmc 0:1 \ efi/debian/grubarm.efi console=${console}
There seems to be a bug with communication lines in U-Boot. So you actually have to put this into a single line.
=> efidebug boot order 0001
Use saveenv if you want to save the settings.
If you do not want to use the internal device tree load the proper device tree, e.g.
=> load mmc 0:2 $fdt_addr_r dtb
Now you are ready to boot via the boot manager:
=> bootefi bootmgr $fdt_addr_r
# Booting via distro defaults
DISTRO_DEFAULTS tries to load the devicetree from ${fdtfile} and the UEFI binary from efi/boot/bootaa64.efi on ARM64. See ./include/config_distro_bootcmd.h.
OpenBSD and FreeBSD follow the distro boot convention, Debian GRUB does not.
Fedora is the same case. I got it working based on your guidance but would be IMHO better to extend distroboot to cover one of the major distribution even through workaround till variable support is done.
# Booting via boot script.
On Debian I use package flash-kernel to keep /boot/dtb in sync with the kernel and have a u-boot.scr.uimg script with something like the following lines:
setenv bootargs console=${console} load mmc 2:1 ${kernel_addr_r} EFI/debian/grubarm.efi load mmc 2:2 ${fdt_addr_r} dtb bootefi ${kernel_addr_r} ${fdt_addr_r}
flash-kernel is interesting. It generates u-boot script but if extX partition has no bootable flag u-boot distroboot ignores it completely. What's your default partition setup?
Alternatively you could use package flash-kernel and implement the /etc/flash-kernel/preboot.d/ hook to start GRUB, cf. /etc/flash-kernel/bootscript/bootscr.uboot-generic
I currently have no Fedora system in use.
you can take a look. https://alt.fedoraproject.org/alt/
