Add OS Build for Khadas VIM4

Description

I am currently looking for future proof SBC hardware I can run Home Assistant on. In the past ODROID N2+ was the best option regarding HA support and performance. However it is already pretty old. This year (2022) some impressive new SBCs are being released. One contender is Khadas VIM4. It would be great if the HA team could add an official HAOS build for this platform. Since they support VIM3, some groundwork has probably already been done.

Odroid N2+ has an image because it’s the underlying hardware behind Home Assistant Blue.

No idea why the “ASUS tikerboard” has its own image, but generally speaking, it’s pretty unrealistic to expect an HAOS image for the hardware of the day, at least until Nabu Casa has become a mega-corpo :smiley:

The supported action plan would be to manage to have Debian 11 running on that board, then install Supervised, or to use a VM.

I agree. However the N2+ is not getting any younger. I think it is time for Nabu Casa to start looking for new, next-gen, easy-to-recommend hardware. And as I said, since they have a HAOS build for VIM3, some groundwork has probably already been done for the VIM4.

I would love official support on VIM4 - I have got HA running on Debian10 (with some changes to removed the unsupported messages) - I have no idea what is comtainined in the VIM3 as I dont have one - surely it must be the same Debian buster from Fenix

I did notice that Fenix has got some Debian 11/VIM4 code… I built it and flashed - booted up. Its hot off the press for me, so no idea in detail what works/doesnt.

hi all,

Any updates about HAOS for VIM4?

7

I cant speak about HAOS , but I have debian11 running on VIM4 with HomeAssistant. It has some problems though - still working through them. It works as a base - just doesnt play nice with Coral and NVR features.

Can you share the image?

Thank you,
AP

So. i’ve build Debian 11 image, and able to install hassio.

Small script for Cassio installation:

#!/bin/bash

cat <<-EOF >> /etc/sysctl.conf
net.ipv6.conf.all.disable_ipv6 = 1
net.ipv6.conf.lo.disable_ipv6 = 1
net.ipv6.conf.eth0.disable_ipv6 = 1

# kernel.dmesg_restrict=0
EOF

sed -i '/boot_user_args/d'  /boot/uEnv.txt

cat <<-EOF >> /boot/uEnv.txt
boot_user_args='cgroup_enable=cpuset cgroup_memory=1 cgroup_enable=memory systemd.unified_cgroup_hierarchy=0 apparmor=1 security=apparmor'
cgroup_enable=cpuset
cgroup_memory=1
cgroup_enable=memory
systemd.unified_cgroup_hierarchy=0
apparmor=1
security=apparmor
EOF

apt install apparmor jq wget curl udisks2 libglib2.0-bin network-manager dbus lsb-release systemd-journal-remote -y
apt install gparted xfsprogs mc vim

systemctl status systemd-journal-gatewayd.socket
systemctl enable --now systemd-journal-gatewayd.socket
systemctl restart  systemd-journal-gatewayd.socket
systemctl status systemd-journal-gatewayd.socket

curl -fsSL get.docker.com | sudo sh

wget https://github.com/home-assistant/os-agent/releases/download/1.4.1/os-agent_1.4.1_linux_aarch64.deb && \
    dpkg -i os-agent_1.4.1_linux_aarch64.deb &&\
    rm os-agent_1.4.1_linux_aarch64.deb

wget https://github.com/home-assistant/supervised-installer/releases/latest/download/homeassistant-supervised.deb && \
    dpkg -i  ./homeassistant-supervised.deb && \
    rm ./homeassistant-supervised.deb

Enjoy.

PS still waiting for official Cassio installation and official debian 11 image.

Nice! … I am making an image - will upload shortly -

just a note that ipv6 is needed for Thread/Matter to work :smiley:

UPDATE: I wont be uploading … 28GB image for a OOWOW emmc backup!
