Requisitos
Gentoo
crossdev -P -v -t aarch64-unknown-linux-gnu
PYTHON=python2 emerge u-boot-tools
ArchLinux
pacman -S uboot-tools aarch64-linux-gnu-binutils aarch64-linux-gnu-gcc aarch64-linux-gnu-glibc aarch64-linux-gnu-linux-api-headers
Preparar o cartão
Limpar
Escrever zeros no inicio do cartão para ter a certeza que não tem restos de outro bootloader.
dd if=/dev/zero of=/dev/sdX bs=1M count=8
Criar Partição
Criar a partição com o inicio a partir do sector 4096.
fdisk /dev/sdX
Filesystem
Criar o filesystem com esta opção hacker que ripei de outro artigo.
mkfs.ext4 -O ^metadata_csum /dev/sdX1
mkswap /dev/sdX2
Copiar o Userland
mkdir /mnt/opipc2
mount /dev/sdX1 /mnt/opipc2
mkdir ~/opipc2
cd ~/opipc2

wget http://archlinuxarm.org/os/ArchLinuxARM-aarch64-latest.tar.gz
bsdtar -xpf ArchLinuxARM-aarch64-latest.tar.gz -C /mnt/opipc2
Gentoo
Sacar o mais recente de http://distfiles.gentoo.org/releases/arm/autobuilds/current-stage3-arm64/
wget http://distfiles.gentoo.org/releases/arm/autobuilds/current-stage3-arm64/stage3-arm64-????????.tar.bz2
tar xfa stage3-arm64-????????.tar.bz2 -C /mnt/opipc2
fstab
Editar o /mnt/opipc2/etc/fstab e usar o seguinte.
<file system> <dir> <type> <options> <dump> <pass> /dev/mmcblk0p1 / ext4 defaults,noatime 0 1 /dev/mmcblk0p2 none swap defaults 0 0
boot.scr
Criar o ficheiro /mnt/opipc2/boot/boot.cmd com o seguinte conteúdo:
part uuid ${devtype} ${devnum}:${bootpart} uuid
#setenv console tty0
setenv bootargs console=${console} root=PARTUUID=${uuid} rw rootwait
setenv fdtfile allwinner/sun50i-h5-orangepi-pc2.dtb
if load ${devtype} ${devnum}:${bootpart} ${kernel_addr_r} /boot/Image; then
if load ${devtype} ${devnum}:${bootpart} ${fdt_addr_r} /boot/dtbs/${fdtfile}; then
if load ${devtype} ${devnum}:${bootpart} ${ramdisk_addr_r} /boot/initramfs-linux.img; then
booti ${kernel_addr_r} ${ramdisk_addr_r}:${filesize} ${fdt_addr_r};
else
booti ${kernel_addr_r} - ${fdt_addr_r};

# Generate with:
# mkimage -A arm -O linux -T script -C none -a 0 -e 0 -n "Orange Pi PC 2 boot script" -d boot.cmd boot.scr
E correr o mkimage para criar o boot.scr.
cd /mnt/opipc2/boot
mkimage -A arm -O linux -T script -C none -a 0 -e 0 -n "Orange Pi PC 2 boot script" -d boot.cmd boot.scr
