Void Linux provides packages and images for several ARM devices. Installing Void on such devices can be done in several ways:
- Pre-built images: images that can be flashed directly onto an SD card or other storage medium, but which give you a limited partition layout, and require manual expansion if you wish to increase the size of the partitions;
- Tarball installation: PLATFORMFS and ROOTFS tarballs that can be extracted to a previously prepared partition scheme; and
- Chroot installation: follows most of the steps outlined in the chroot guide.
This guide also outlines configuration steps that are mostly specific to such devices.
Since most of the commands in this guide will be run on external storage, it is important to run sync(1) before removing the device.
If you are installing Void Linux on one of the ARM devices covered in the "Supported platforms" page, make sure to read its section thoroughly.
# dd if=<image>.img of=/dev/mmcblk0 bs=4M status=progress
Customizing an installation - for example, with a custom partition layout - requires a more involved process. Two available options are:
To prepare the storage for these installation methods, it is necessary to partition the storage medium and then mount the partitions at the correct mount points.
The usual partitioning scheme for ARM devices requires at least two partitions, on a drive formatted with an MS-DOS partition table:
- one formatted as FAT32 with partition type
0c, which will be mounted on
- one that can be formatted as any file system that Linux can boot from, such as
ext4, which will be mounted on
/. If you're using an SD card, you can create the ext4 file system with the
^has_journaloption - this disables journaling, which might increase the drive's life, at the cost of a higher chance of data loss.
There are a variety of tools available for partitioning, e.g. cfdisk(8).
To access the newly created file systems, it is necessary to mount them. This
guide will assume that the second partition will be mounted on
/mnt, but you
may mount it elsewhere. To mount these filesystems, you can use the commands
below, replacing the device names with the appropriate ones for your setup:
# mount /dev/mmcblk0p2 /mnt
# mkdir /mnt/boot
# mount /dev/mmcblk0p1 /mnt/boot
# tar xvfp <image>.tar.xz -C /mnt
It is also possible to perform a chroot installation using the appropriate architecture and base packages, some of which are listed in the "Supported Platforms" section. Make sure to prepare your storage medium properly for the device.
If doing this from a computer with an incompatible archtecture (such as x86_64),
binfmt-support packages and enable the
binfmt-support service before installing.
Some additional configuration steps need to be followed to guarantee a working system. Configuring a graphical session should work as normal.
For the pre-built images and tarball installations, the
root user password is
/boot partition should be added to
/etc/fstab, with an entry similar to
the one below. It is possible to boot without that entry, but updating the
kernel package in that situation can lead to breakage, such as being unable to
find kernel modules, which are essential for functionality such as wireless
connectivity. If you aren't using an SD card, replace
/dev/mmcblk0p1 with the
appropriate device path.
/dev/mmcblk0p1 /boot vfat defaults 0 0
Several of the ARM devices supported by Void Linux don't have battery powered
real time clocks (RTCs), which means they won't keep track of time once powered
off. This issue can present itself as HTTPS errors when browsing the Web or
using the package manager. It is possible to set the time manually using the
date(1) utility. In order to fix this issue
for subsequent boots, install and enable an NTP
client. Furthermore, it is possible to
fake-hwclock package, which provides the
fake-hwclock(8) periodically stores
the current time in a configuration file and restores it at boot, leading to a
better initial approximation of the current time, even without a network
Warning: Images from before 2020-03-16 might have an issue where the
installation of the
chrony package, the default NTP daemon, is incomplete, and
the system will be missing the
chrony user. This can be checked in the output
of the getent(1) command, which will be
empty if it doesn't exist:
$ getent group chrony
In order to fix this, it is necessary to reconfigure the
chrony package using
xf86-video-fbturbo package ships a modified version of the DDX Xorg
driver found in the
xf86-video-fbdev package, which is optimized for ARM devices. This can be used
for devices which lack more specific drivers.
