ODROID-C1-FreeBSD

Prerequisites

You need a working FreeBSD installation with an installed source-tree

Clone this repo: git clone https://github.com/KizzyCode/ODROID-C1-FreeBSD ~/odroidc1

Create our root partition

# Become root and change into our working dir
su
cd ~/odroidc1/build

# Create an image for the root partition and attach it to `/dev/md0`
truncate -s 1024M root.img
mdconfig -f root.img -u0

# Create a new FS in the image and mount it
# ! Make sure that `/dev/md0` is your image !
newfs /dev/md0
mount /dev/md0 /mnt

# PATCH: Install older meson.dtsi-version (see http://freebsd.1045724.x6.nabble.com/odroidc1-build-kernel-fails-td6318210.html)
fetch -o /usr/src/sys/gnu/dts/arm/meson.dtsi "https://svnweb.freebsd.org/base/releng/11.1/sys/gnu/dts/arm/meson.dtsi?revision=320486&view=co&pathrev=324819"

# Build FreeBSD for ARMv6 and install it into the root image
cd /usr/src
make clean
make -j8 TARGET=arm TARGET_ARCH=armv7 kernel-toolchain
make -j8 TARGET=arm TARGET_ARCH=armv7 KERNCONF=ODROIDC1 buildkernel
make -j8 TARGET=arm TARGET_ARCH=armv7 buildworld
make -j8 TARGET=arm TARGET_ARCH=armv7 DESTDIR=/mnt installworld distribution

# Copy the `fstab` to the root image
cd ~/odroidc1/build
cp fstab /mnt/etc/

# Unmount and detach the root image
umount /mnt
mdconfig -d -u0

Create and attach our SD-card image

# Create the SD-card image and attach it to `/dev/md0`
truncate -s 2048M sd.img
mdconfig -f sd.img -u0

Install our bootloader and prepare the SD card

You need to either download my precompiled bootloader or compile it yourself.

For now I assume that you use the precompiled version:

cd ~/odroidc1/build/sd_fuse

# ! Make sure that `/dev/md0` is your image !
bash ./sd_fusing.sh /dev/md0

Prepare the boot partition

cd ~/odroidc1/build

# ! Make sure that `/dev/md0` is your image !
mount -t msdosfs /dev/md0s1 /mnt

# Copy the boot files
cp /usr/obj/arm.armv6/usr/src/sys/ODROIDC1/kernel.bin /mnt/
cp boot.ini /mnt/
umount /mnt

Copy our root partition to the SD-card image

# ! Make sure that `/dev/md0` is your image !
dd if=root.img of=/dev/md0s2 bs=4096k

# Adjust the partition size
# ! Make sure that `/dev/md0` is your image !
growfs /dev/md0s2

# Detach SD-card image
mdconfig -d -u0

Now your SD-card image should be ready 🎉

Post-install steps (can be performed on the ODROID itself)

Set a root password (currently an empty password is set) and configure /etc/rc.conf:

# General
clear_tmp_enable="YES"
dumpdev="NO"
syslogd_flags="-ss"
hostname="Kizzys-ODROID"
keymap="de.acc"

# Services
sshd_enable="YES"
sendmail_enable="NONE"
ntpd_enable="YES"
ntpdate_enable="YES"
geom_eli_load="YES"
jail_enable="YES"

# Time and date
ntpd_enable="YES"
ntpdate_enable="YES"

# Network
rtsold_enable="YES"
ifconfig_dwc0="DHCP"
ifconfig_dwc0_ipv6="inet6 accept_rtadv"
