Hi system-devl team,
Nice to meet you.
I am having trouble to boot the unified-kernel image when using systemd's EFI
stub loader, I wanted to check in this community if I can get some help to fix
this problem.
Here are steps I followed:
I am using Debian package versions while checking this.
Systemd: 251~rc1
Bintutils(objcopy): 2.38
Kernel versio: 5.10
I built the kernel image for arm64:
kernel_image_file= linux_src/arch/arm64/boot/Image
Created unified kernel image using objcopy as below
(on arm64 machine)
```
objcopy \
--add-section .osrel="${os_release_file}" --change-section-vma
.osrel=0x20000 \
--add-section .cmdline="${kernel_cmd_line_file}" --change-section-vma
.cmdline=0x30000 \
--add-section .linux="${kernel_image_file}" --change-section-vma
.linux=0x2000000 \
--add-section .initrd="${initrd_image_file}" --change-section-vma
.initrd=0x3000000 \
/usr/lib/systemd/boot/efi/linuxaa64.efi.stub unified-kernel.efi ```
I tried to boot this unified-kernel image in EFI Shell environment and got the
below error ``` EFI shell> fs0:
FS0:\> unified-kernel.efi
call the kernel
EFI stub: Booting Linux Kernel...
EFI stub: Generating empty DTB
EFI stub: Loaded initrd from LINUX_EFI_INITRD_MEDIA_GUID device path EFI stub:
Exiting boot services and installing virtual address map...
```
Looks like the kernel image file (Image) is loaded and went through kernel EFI
stub and then stuck, I didn’t any clue why this is stuck.
When I use uncompressed version of linux image (vmlinux) in objcopy, then it
got the error much earlier probably at EFI stub loader ``` EFI shell> fs0:
FS0:\> unified-kernel.efi
Command Error Status: Load Error
```
Can anyone suggest me how can I solve this?
Thanks,
Venkata.
