- Bug fixes
- Fixes an issue where query parameters would be percent-encoded twice.
Packages that use
query_params
argument option toartifact_sites
could be impacted. For example, packages storing build artifacts in AWS S3 require theX-Amz-Credential
query parameter key whose value includes the reserved character/
. This symbol is double encoded to%252F
. This failed on systems with Erlang OTP-23.2 and above. See nerves-project#604 for additional context.

- Documentation and docker improvements for Windows Subsystem for Linux 2
Nerves 1.7.0 removes support for creating OTP releases using Distillery and only supports using Elixir releases. As a result, the minimum supported version of Elixir is now version 1.9.
Official Nerves systems now support applying firmware using patches. This greatly reduces the amount of data that required to push firmware updates to devices. The minimum requirement for fwup has been updated to 1.8 to enable support for this feature.

- Pass all unspecified erlinit args to the generator instead of silently ignoring them.
- Use host CC when compiling the port.
- Bug fixes
- Fix issues with executing system commands on non mac hosts.
-
Experimental features
-
Added
mix firmware.patch
to locally create firmware patch files for feature testing. This feature is under development. See the experimental features doc for more info. -
Added
:mksquashfs_flags
to the nerves firmware config to allow passing additional flags to themksquashfs
call that produces the final rootfs. If you are experimenting with creating patchable firmware, you should use this feature to disable squashfs compression.config :nerves, :firmware mksquashfs_flags: ["-noI", "-noD", "-noF", "-noX"]

Bug fixes
- Replace calls to
System.cmd
with aNerves.Port.cmd
. This code was provided bymuontrap
and is used to clean up spawned system processes when the vm exits. This fixes issues with the docker build runner executing multiple times and multiple calls tomix firmware
after breaking out of the VM before the first call finishes. - Fix issue where SD card detection may fail while calling
mix burn
whenfwup
returns additional fields. - Clean the release directory when calling
mix firmware
. This prevents OTP releases from accumulating unnecessary libraries and OTP applications over time.
- Replace calls to

-
Bug fixes
-
Improve error message returned when calling
mix firmware
when the local system artifact cannot be found and possibly needs to be built. -
GitHub API artifact resolver will no longer raise if missing required opts.
The GitHub API artifact resolver is useful when you want to enable access to artifacts added to GitHub releases in private GitHub repositories. Fetching an artifact from a private GitHub repo requires the passing
username, token, tag
as options. If any of these options were omitted, the resolver would raise and prevent compilation from continuing. This is problematic when you are trying to actually compile the system in CI. Artifact resolvers should make a best effort on downloading the artifacts, and return{:error, reason}
if they are unsuccessful. This will allow the system to fall back to performing a compile. -

Nerves 1.6.0 adds support for Elixir 1.10.
As part of the update to Elixir 1.10, it became more difficult to support old
Elixir and Erlang versions. Therefore, Nerves 1.6.0 requires at least Elixir
v1.7.0 and Erlang/OTP 21. If your project requires an older version of Elixir or
Erlang/OTP you can pin the version of nerves
to an older version.
For example, set your nerves dependency in your mix.exs to:
{:nerves, "~> 1.5.0", runtime: false},
- Enhancements
- Add support for aarch64 host architecture.
- Add
mix firmware.metadata
for listing firmware metadata values.

- Always generate
erlinit.config
, even if there are no config override in mix config. This fixes an issue where removing overrides from mix config would not update the erlinit.config.
- Invoke
- Bug fixes
- Fix various erlinit option parsing/formatting issues.
-
Enhancements
-
erlinit.config options can be overridden using the application config now. For example, in your config.exs you can now add:
config :nerves, :erlinit, ctty: "ttyAMA0"
-
Nerves tooling now supports setting the SOURCE_DATE_EPOCH environment variable for reproducible builds during compilation via
:source_date_epoch
in your application config. This removes timestamp differences between builds. See reproducible-builds.org for more information. -
Windows Subsystem for Linux improvements
-
Support XDG_DATA_HOME. If XDG_DATA_HOME is set, Nerves will now store its data under that directory.
-
-
Bug fixes
- Do not require sudo on
mix burn
if already privileged. - Keep all boot scripts. Previously, extraneous boot scripts from the OTP release process were removed. Keeping them makes it possible to start Erlang slave nodes and support use cases where triggers at device boot time launch different scripts.
- Do not require sudo on

- Improve error message when artifacts can't be found
Version v1.4.0 adds support for Elixir 1.8's new built-in support for mix
targets. In Nerves, the MIX_TARGET
was used to select the appropriate set of
dependencies for a device. This lets you switch between building for different
boards and your host. Elixir 1.8 pulls this support into mix
and lets you
annotate dependencies for which targets they should be used.

Nerves.Artifact.BuildRunners.Docker
was running as root and caused file permission issues with thedeps
directory of the rootmix
project. TheDocker
build runner now executes as the same user id and group id as the host.
This version renames the module Nerves.Artifact.Provider
to
Nerves.Artifact.BuildRunner
. This change should only affect custom systems
and host tools that override the defaults in nerves_package
config.
- Enhancements
- Allow specifying multiple rootfs_overlay directories in the config.
- Automatically remove corrupt files from the download directory.
- Updated System documentation.
- Bug Fixes
- Check the download directory before attempting to download the artifact.
- Changed the host tool check to use
System.find_executable("command")
instead of calling out toSystem.cmd("which", ["command"])
. This addressed an issue with NodeJS breaking anything that called intowhich
resulting in an obscure error.
This rc contains documentation cleanup and updates through out.
-
Enhancements
-
Support forwarding the ssh-agent through Docker for the Nerves system shell.
-
Allow headers and query params to be passed to the
:prefix

helper.Example:
{:prefix, "https://my_server.com/", headers: [{"Authorization", "Basic 1234"}]}
{:prefix, "https://my_server.com/", query_params: %{"id" => "1234"}}
-
Added
github_api

Nerves no longer automatically compiles any nerves_package
that is missing its
pre-compiled artifact. This turned out to rarely be desired and caused
unexpectedly long compilation times when things like the Linux kernel or gcc got
compiled.
When a pre-compiled artifact is missing, Nerves will now tell you what your
options are to resolve this. It could be retrying mix deps.get
to download it
again. If you want to force compilation to happen, add a :nerves
option for
the desired package in your top level project:
{:nerves_system_rpi0, "~> 1.0-rc", nerves: [compile: true]}
- Bug Fixes

before trying to link to build path artifacts - raise if artifact_urls are not binaries.
- Update Notes
Starting in Nerves v0.9.0, artifacts will no longer be fetched during mix compile
. Artifact archives are intended to be fetched following mix deps.get
.
To handle this, you will need to update your installed version of
nerves_bootstrap
by calling mix nerves.local
. After updating
nerves_bootstrap
, you should update your mix.exs
file to add the new
required mix aliases found there. A helper function is available named
Nerves.Bootstrap.add_aliases
that you can pipe your existing aliases to like
this:
defp aliases(_target) do
[
# Add custom mix aliases here
]
|> Nerves.Bootstrap.add_aliases()
end
Also, update your nerves dependency to:
{:nerves, "~> 0.9", runtime: false}

-
Added Mix task
nerves.artifact.get
. Use to fetch the artifact archive from anartifact_url
location. Once downloaded its checksum will be checked againstartifact_checksum
from thenerves_package

will recursively callnerves.artifact.get
to fetch archives. -
Added Mix task
nerves.artifact
. This task will produce the artifact archive file which are used when callingnerves.artifact.get
. -
Nerves packages can override the Provider in the
nerves_package
config inmix.exs
using the keysprovider
andprovider_opts
. This is useful to force a package to build using a specific provider likeNerves.Artifact.Providers.Docker
. See the package configuration docs for more information. -
Added
artifact_sites
to thenerves_package
config. Artifact sites are helpers that are useful for cleanly specifying locations where artifacts can be fetched. If you are hosting your artifacts using Github releases you can specify it like this:artifact_sites: [ {:github_releases, "organization/project"} ]
You can also specify your own custom server location by using the
:prefix
helper by passing a url or file path:artifact_sites: [ {:prefix, "/path/to/artifacts"} {:prefix, "https://my_bucket.s3-east.amazonaws.com/artifacts"} ]
Artifact sites will be tried in order until one successfully downloads the artifact.

Revert plugin Nerves in new project generator until the fix can be made in distillery. This issue was causing the release to contain compiled libraries from the host instead of the target. The error would look similar to this
