Installing Arch Linux ARM

  1. Download the Arch Linux ARM tarball:

     wget http://os.archlinuxarm.org/os/ArchLinuxARM-aarch64-latest.tar.gz

  2. Install Archive Tools:

     sudo apt install libarchive-tools

  3. Mount the target drive:

     sudo mkdir /mnt/chroot
 sudo mount /dev/sdXy /mnt/chroot
 sudo mount /dev/sdXz /mnt/chroot/boot/efi
 cd /mnt/chroot/
 sudo mount -t proc /proc proc
 sudo mount --make-rslave --rbind /sys sys
 sudo mount --make-rslave --rbind /dev dev
 sudo mount --make-rslave --rbind /run run

  4. Extract the tarball to the mounted drive:

     bsdtar -xpf ArchLinuxARM-aarch64-latest.tar.gz -C /mnt/chroot

  5. Chroot into Arch Linux install:

     sudo chroot /mnt/chroot /bin/bash

  6. Initiate Pacman:

     pacman-key --init
 pacman-key --populate archlinuxarm

  7. Download and extract the kernel: [Non-SolidRun kernel; Need to Update] [Modify to your needs]

     mkdir /home/alarm/build/kernel && cd /home/alarm/build/kernel
 wget https://cdn.kernel.org/pub/linux/kernel/v5.x/linux-5.14.6.tar.xz
 tar -xvf linux-5.14.6.tar.xz
 cd linux-5.14.6.tar.xz

  8. Copy host linux running kernel config:

     exit
 cp /boot/config-<version> /mnt/chroot/home/alarm/build/kernel/linux-5.14.6/.config   [Select the one reflecting current kernel (uname -a)]
 sudo chroot /mnt/chroot /bin/bash
 cd /home/alarm/build/kernel

  9. Modify .config file: [Modify the following lines...] [Use CTRL+W to search for values, CTRL+W again to find the next instance]

     nano .config

 CONFIG_LOCALVERSION="-1-ARCH"
 #CONFIG_MODULE_SIG_KEY=""
 #CONFIG_SYSTEM_TRUSTED_KEYS=""
 #CONFIG_CRYPTO_AEGIS128

  10. Run the build:

     make -j12 && make modules -j12 && make modules_install

  11. Copy "bzImage/Image" to boot directory:

     cp arch/arm64/boot/Image /boot/vmlinuz-linux514

  12. Generate initramfs:

     pacman -Sy cpio mkinitcpio-nfs-util mkinitcpio-archiso
 mkinitcpio -k 5.14.6-1-ARCH -g /boot/initramfs-linux514.img

  13. Install Grub:

     grub-install --target=arm64-efi --efi-directory=/boot/efi --bootloader-id=GRUB
 grub-mkconfig -o /boot/efi/EFI/grub/grub.cfg

  14. Configure Grub Linux defaults:

     nano /etc/default/grub

   GRUB_CMDLINE_LINUX_DEFAULT="nomodeset loglevel=4 arm-smmu.disable_bypass=0 amdgpu.pcie_gen_cap=0x4 amdgpu.noretry=1"

  15. Set root permissions:

     chmod 755 /
 chmod 755 /bin
 chmod 755 /lib

  16. Reboot LX2K and boot into your new install using the BIOS.

  17. Log into your new install with root/root.

  18. Set new root password:

     passwd root

  19. Edit resolv.conf:

     nano /etc/resolv.conf

 nameserver 8.8.8.8

  20. Update system:

     pacman -Syyu

  21. Install Gnome: [At time of writing, still working on Mesa GNOME driver patch]

     pacman -Sy gnome-desktop
 sytemctl enable gdm

NOTES:

  1. If Terminal doesnt launch under Gnome, install Terminator, it works fine. Currently troubleshooting.
  2. Graphical issues abound. Currently troubleshooting.
