ODROID-HC1: Arch Linux ARM

Wed, 08 May 2019 21:02:30 +0200

Steps for installing Arch Linux on separate boot and root disk.

Preparation

Set variable to the name of your SD card.
```
BOOTDEV=/dev/sdX
```
Set variable to the name of your SATA drive.
```
ROOTDEV=/dev/sdY
```

Partitioning & formatting

Create 128 MB boot partition on SD card

parted -s $BOOTDEV mklabel msdos
parted -s $BOOTDEV mkpart primary fat32 4096s 128MiB

Create 10 GB root partition on SATA drive

parted -s $ROOTDEV mklabel msdos
parted -s $ROOTDEV mkpart primary ext4 4096s 10GiB

Create corresponding filesystems

mkfs.vfat -F 32 -n BOOT ${BOOTDEV}1
mkfs.ext4 -L rootfs ${ROOTDEV}1

Mount boot inside of root filesystem

mkdir /mnt/a
mount ${ROOTDEV}1 /mnt/a
mkdir /mnt/a/boot
mount ${BOOTDEV}1 /mnt/a/boot

Installation

Download and extract Arch base system

bsdtar -xpf ArchLinuxARM-odroid-xu3-latest.tar.gz -C /mnt/a

Configuration

Set hostname, localization, time zone, network configuration and filesystem mounting

cd /mnt/a
echo server > etc/hostname
echo LANG=de_DE.UTF-8 > etc/locale.conf
sed -i '/^#de_DE/ s/^#//g' etc/locale.gen
ln -sf /usr/share/zoneinfo/Europe/Berlin etc/localtime
echo -e "127.0.0.1\tlocalhost.localdomain\tlocalhost" >> etc/hosts
echo -e "::1\t\tlocalhost.localdomain\tlocalhost" >> etc/hosts
sed -i '/^DHCP=/ s/=.*/=ipv6/' etc/systemd/network/eth0.network
echo Address=192.168.1.2/24 >> etc/systemd/network/eth0.network
echo Gateway=192.168.1.1 >> etc/systemd/network/eth0.network
echo DNS=192.168.1.1 >> etc/systemd/network/eth0.network
echo NTP=192.168.1.1 >> etc/systemd/network/eth0.network
echo -e "LABEL=BOOT\t\t/boot\t\tvfat\t\tdefaults\t0 2" >> etc/fstab
echo -e "LABEL=rootfs\t\t/\t\text4\t\tdefaults,noatime\t0 1" >> etc/fstab

Update bootloader files

cd boot
sed -i '/^part uuid/ s/^/#/' boot.txt
sed -i '/^setenv bootargs/ s/PARTUUID=${uuid}/LABEL=rootfs/' boot.txt
sed -i '/load/ s/\/boot\//\//g' boot.txt
bash mkscr
bash sd_fusing.sh ${BOOTDEV}

Clean up

Unmount filesystems

cd ~
umount /mnt/a/boot /mnt/a
rmdir /mnt/a

First boot

Connect both disks to your HC1 and fire it up.
