Hello,
Tried to take on this challenge with very moderate success. That is not surprising being a
complete NOOB in regards to UEFI and never doing more than the usual-user stuff with GRUB.
(So bear with me and have a little patients..)
I am working with FC29 (Kernel 4.18.16-300) now, if it is better to work with FC28 please
comment on that.
Did not dive in detail into the necessary bootloaders and additions (fib/create ??) to
main-line uboot because I nicked two apparently working boot-loading stacks from other
distros. One originates from a (UEFI) booting Suse image and one from a Arch Linux ARM
package (2). Cross checked the Alarm bootloaders with the Suse image which booted with it.
Looking at the PKGBUILD it is a pristine as you can gat and decided to go with it for the
time being.
The autoboot was unsuccessful with both bootloader-stacks with more or less the same
errors:
## Starting EFI application at 01080000 ...
System BootOrder not found. Initializing defaults.
Could not read \EFI\: Invalid Parameter
Error: could not find boot options: Invalid Parameter
start_image() returned Invalid Parameter
## Application terminated, r = 2
EFI LOAD FAILED: continuing...
See autoboot ‘alarm-mainline-uboot’ and ‘autoboot suse-uboot’ (1) for full logs
After stopping autoboot and loading grub manual form the u-boot shell:
(see ‘manual booteufi’ (1))
=> load mmc 0:2 ${fdt_addr_r} /dtb/amlogic/meson-gxbb-odroidc2.dtb
=> load mmc 0:1 ${kernel_addr_r} /EFI/fedora/grubaa64.efi
=> bootefi ${kernel_addr_r} ${fdt_addr_r}
The kernel does boot and starts system (PID 1) to stop there.
see also (1) ‘kernel boot’
Meanwhile I added :
console=ttyAML0,115200n8 earlycon
to the kernel cmdline and removed Plymouth entirely to see as much as possible on the
serial-monitor.
First things first:
How do I get the EUFI autoboot playing along without compiling a u-boot script with the
above commands which led to load grub ?
And to be frank I am a bit stuck right now..
- Is system unable to (re)mount the initrootfs ?
- Does my serial monitor die on me?
All suggestion are welcome!
Thaks and greeting Mark
