Mike Tango Bravo · Updated 2024-04-18

Add a pisugar user to the PiKVM (Raspberry Pi):

Connect via ssh to the PiKVM device.
Add a pisugar user:

[root@pikvm ~]# rw         
+ mount -o remount,rw /
+ mount -o remount,rw /boot
+ set +x
=== PiKVM is in Read-Write mode ===
useradd --system -s /usr/bin/bash pisugar
usermod -d /opt/pisugar -m pisugar
passwd pisugar

Add pisugar to /etc/sudoers
Download latest pisugar-archlinux_<version>_all.tar.gz from Releases · PiSugar/pisugar-power-manager-rs

su - pisugar
tar -xvf pisugar-archlinux_<version>_all.tar.gz

Edit the PKBUILD to support the RPi Zero 2W:

arch=('arm' 'armhf' 'armv7h' 'aarch64' 'x86_64')

and change the line to say (cd armhf)

Fix the install script sed error

[pisugar@pikvm pisugar-archlinux]$ cat install.sh
#!/bin/sh

set -e

version=$(cat PKGBUILD | grep ^pkgver | awk -F = '{print $2}')

sudo pacman -Sy binutils make gcc pkg-config fakeroot

makepkg -si

echo "PiSugar hardware model:"
select model in "PiSugar 3" "PiSugar 2 Pro" "PiSugar 2 (2-LEDs)" "PiSugar 2 (4-LEDs)"; do
    if [ "x$model" != "x" ]; then
        break;
    fi
done

echo "Model: $model"
sudo sed -e "s/--model.*--/--model '$model' --/" \
    -i /etc/default/pisugar-server/pisugar-server.default  \
    -i /etc/default/pisugar-poweroff/pisugar-poweroff.default  \
    || true

sudo systemctl enable pisugar-server || true
sudo systemctl start pisugar-server || true

then move the files /etc/default/pisugar-server/pisugar-server.default to /etc/default/pisugar-server
Install i2c-tools
pacman -Sy i2c-tools
Enable the i2c kernel module
