Does not work. This is just a documentation of my results, what I found out and what might be a good starting point for someone else, trying the same thing. Hope it helps.

Zero the beginning of the SD card:
dd if=/dev/zero of=/dev/sdX bs=1M count=32
Start parted to partition the SD card:
parted /dev/sdX
At the parted prompt, create 5 new partitions:
- Type
unit sto use sectors as unit. - Type
mklabel gptto create the partition table. - Type
mkpart logical ext2 64 8063to create the first partition. It will tell you thatThe resulting partition is not properly aligned for best performance..Ignorethis warning. - Type
mkpart logical ext2 16384 24575to create the second partition. - Type
mkpart logical ext2 24576 32767to create the third partition. - Type
mkpart logical fat32 32768 262143to create the EFI boot partition. - Type
mkpart logical ext2 262144 100%to create the linux filesystem partition. - Type
set 4 boot onto set the filesystem type for partition 4 to EF00
As a result you should get the following partition table (this output is the partition table of the official Ubuntu server image for Rock Pi 4):
Disk /dev/sdh: 29.7 GiB, 31914983424 bytes, 62333952 sectors
Disk model: STORAGE DEVICE
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disklabel type: gpt
Disk identifier: 992DF2C2-0170-4F66-9492-FBF320673EEF
Device Start End Sectors Size Type
/dev/sdh1 64 8063 8000 3.9M Linux filesystem
/dev/sdh2 16384 24575 8192 4M Linux filesystem
/dev/sdh3 24576 32767 8192 4M Linux filesystem
/dev/sdh4 32768 262143 229376 112M EFI System
/dev/sdh5 262144 62333918 62071775 29.6G Linux filesystem
Create the filesystems for the EFI and the linux partition:
mkfs.fat -F32 /dev/sdX4
mkfs.ext4 /dev/sdX5
Write the data for the three other partitions:
wget http://os.archlinuxarm.org/os/rockchip/boot/rock64/idbloader.img
wget http://os.archlinuxarm.org/os/rockchip/boot/rock64/uboot.img
wget http://os.archlinuxarm.org/os/rockchip/boot/rock64/trust.img
dd if=idbloader.img of=/dev/sdX seek=64
dd if=uboot.img of=/dev/sdX seek=16384
dd if=trust.img of=/dev/sdX seek=24576
Mount the partitions:
mkdir root
mount /dev/sdX5 root
mkdir boot
mount /dev/sdX4 boot
Download and install the ArchLinuxARM base:
wget http://os.archlinuxarm.org/os/ArchLinuxARM-aarch64-latest.tar.gz
bsdtar -xpf ArchLinuxARM-aarch64-latest.tar.gz -C root
Move the boot data to the boot partition and register this new partition in
the fstab:
mv root/boot/* boot/
echo "/dev/mmcblk0p4 /boot vfat defaults 0 1" >> root/etc/fstab
Ensure that everything is written to the SD card:
sync
This is how far I got. It does not boot. I guess, one issue is, that the boot partition does not really contain the EFI data. But I also guess, that there are more issues.
If you get further than me, update this guide and let me now!
Appears the link does not exist anymore^^...
@benhubert any further updates to this?
Did you try to flash the official Ubuntu Server version, keep or analyze the boot partitions?
