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

ArchLinux

$ 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};
    fi;
  fi;
fi

# 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
