# Changelog
## v2.12.1
This is a security/bug fix patch release. It should be safe to update for
everyone.
* Updated dependencies
* [nerves_system_br v1.17.1](https://github.com/nerves-project/nerves_system_br/releases/tag/v1.17.1)
* [Buildroot 2021.08.1](http://lists.busybox.net/pipermail/buildroot/2021-October/625642.html)
* [Erlang/OTP 24.1.2](https://erlang.org/download/OTP-24.1.2.README)
* Improvements
* Include software versioning and licensing info (see legal-info directory in
artifact)
## v2.12.0
This release updates to Buildroot 2021.08 and OTP 24.1. If you have made a
custom system off this one, please review the `nerves_system_br v1.17.0` release
notes.
* Updated dependencies
* [nerves_system_br v1.17.0](https://github.com/nerves-project/nerves_system_br/releases/tag/v1.17.0)
* [Buildroot 2021.08](http://lists.busybox.net/pipermail/buildroot/2021-September/622072.html)
* [Erlang/OTP 24.1](https://erlang.org/download/OTP-24.1.README)
## v2.11.2
This release updates Erlang/OTP from 24.0.3 to 24.0.5 and Buildroot from 2021.05
to 2021.05.1. Both of these are security/bug fix updates. This is expected to be
a safe upgrade from v1.16.1 for all users.
* Updated dependencies
* [nerves_system_br v1.16.4](https://github.com/nerves-project/nerves_system_br/releases/tag/v1.16.1)
* [Erlang/OTP 24.0.5](https://erlang.org/download/OTP-24.0.5.README)
* Improvements
* Beta support for using a `runtime.exs` script for runtime configuration.
* Added a `provision` task to the `fwup.config` to enable re-provisioning a
MicroSD card without changing its contents.
* Adds a default `/etc/sysctl.conf` that enables use of ICMP in Erlang. This
requires `nerves_runtime v0.11.5` or later to automatically load the sysctl
variables. With it using `:gen_udp` to send/receive ICMP will "just work".
It also makes it easier to add other sysctl variables if needed.
## v2.11.1
This release updates Nerves Toolchains to v1.4.3 and OTP 24.0.3. It should be safe for everyone to apply.
* Updated dependencies
* [nerves_system_br v1.16.1](https://github.com/nerves-project/nerves_system_br/releases/tag/v1.16.1)
* [Erlang/OTP 24.0.3](https://erlang.org/download/OTP-24.0.3.README)
* [nerves toolchains v1.4.3](https://github.com/nerves-project/toolchains/releases/tag/v1.4.3)
* Improvements
* bborg-overlays: bump to latest SHA (device tree updates for BBB)
## v2.11.0
This release updates to Buildroot 2021.05 and OTP 24.0.2. If you have made a
custom system off this one, please review the `nerves_system_br v1.16.0` release
notes.
* Updated dependencies
* [nerves_system_br v1.16.0](https://github.com/nerves-project/nerves_system_br/releases/tag/v1.16.0)
* [Buildroot 2021.05](http://lists.busybox.net/pipermail/buildroot/2021-June/311946.html)
* [Erlang/OTP 24.0.2](https://erlang.org/download/OTP-24.0.2.README)
* Improvements
* This release now contains debug symbols and includes the Build-ID in the
ELF headers. This makes it easier to get stack traces from C programs. As
before, the Nerves tooling strips all symbols from firmware images, so this
won't make programs bigger.
* Enable compile-time `wpa_supplicant` options to support WPA3, mesh
networking, WPS and autoscan.
## v2.10.1
This is a security/bug fix release that updates to Buildroot 2021.02.1 and OTP
23.3.1. It should be safe for everyone to apply.
* Updated dependencies
* [nerves_system_br v1.15.1](https://github.com/nerves-project/nerves_system_br/releases/tag/v1.15.1)
* [Buildroot 2021.02](http://lists.busybox.net/pipermail/buildroot/2021-April/307970.html)
* [Erlang/OTP 23.3.1](https://erlang.org/download/OTP-23.3.1.README)
## v2.10.0
This release updates to Buildroot 2021.02 and OTP 23.2.7. If you have made a
custom system off this one, please review the `nerves_system_br v1.15.0` release
notes.
The Nerves toolchain has also been updated to v1.4.2. This brings in Linux 4.14
headers to enable use of cdev and eBPF. This won't affect most users.
* Updated dependencies
* [nerves_system_br v1.15.0](https://github.com/nerves-project/nerves_system_br/releases/tag/v1.15.0)
* [Buildroot 2021.02](http://lists.busybox.net/pipermail/buildroot/2021-March/305168.html)
* [Erlang/OTP 23.2.7](https://erlang.org/download/OTP-23.2.7.README)
* [nerves toolchains v1.4.2](https://github.com/nerves-project/toolchains/releases/tag/v1.4.2)
## v2.9.0
This release updates to Buildroot 2020.11.2, GCC 10.2 and OTP 23.2.4.
When migrating custom systems based, please be aware of the following important
changes:
* There's a new `getrandom` syscall that is made early in BEAM startup. This has
the potential to block the BEAM before Nerves can start `rngd` to provide
entropy. We have not seen this issue here, but have updated `erlinit.config`
for the time being as a precaution.
* The GCC 10.2.0 toolchain has a different name that calls out "nerves" as the
vendor and the naming is now more consistent with other toolchain providers.
* Experimental support for tooling that requires more information about the
target has been added. The initial support focuses on zigler.
* Updated dependencies
* [nerves_system_br: bump to v1.14.4](https://github.com/nerves-project/nerves_system_br/releases/tag/v1.14.4)
* [Buildroot 2020.11.2](http://lists.busybox.net/pipermail/buildroot/2021-January/302574.html)
* [Erlang/OTP 23.2.4](https://erlang.org/download/OTP-23.2.4.README)
* [Nerves toolchains 1.4.1](https://github.com/nerves-project/toolchains/releases/tag/v1.4.1)
## v2.8.3
This is a bug fix release with no major changes.
* Updated dependencies

2020.08.2](http://lists.busybox.net/pipermail/buildroot/2020-November/296830.html).
* Updated dependencies
* [nerves_system_br: bump to v1.13.5](https://github.com/nerves-project/nerves_system_br/releases/tag/v1.13.5)
* [erlinit 1.9.0](https://github.com/nerves-project/erlinit/releases/tag/v1.9.0)
## v2.8.1
The main change in this release is to bump the Linux kernel to 5.4.
If you have based a custom system off of this one, please inspect the
`linux-5.4.defconfig` for changes. There were only a few changes, but
if you are modifying the kernel configuration, please review first.
* Updated dependencies
* [nerves_system_br: bump to v1.13.4](https://github.com/nerves-project/nerves_system_br/releases/tag/v1.13.4)
* [Erlang/OTP 23.1.4](https://erlang.org/download/OTP-23.1.4.README)
* [boardid 1.10.0](https://github.com/nerves-project/boardid/releases/tag/v1.10.0)
* Improvements
* Enabled reproducible builds in Buildroot to remove some timestamp and build
path differences in firmware images. This helps delta firmware updates.
## v2.8.0
This release updates to [Buildroot
2020.08](http://lists.busybox.net/pipermail/buildroot/2020-September/290797.html) and OTP 23.1.1.
* Updated dependencies
* [nerves_system_br: bump to v1.13.2](https://github.com/nerves-project/nerves_system_br/releases/tag/v1.13.2)

* New features
* Added support for updating the root filesystem using firmware patches.
See the [firmware patch docs](https://hexdocs.pm/nerves/experimental-features.html#content) for more information.
## v2.7.2
This release updates to [Buildroot
2020.05.1](http://lists.busybox.net/pipermail/buildroot/2020-July/287824.html)
and OTP 23.0.3 which are both bug fix releases.
* Updated dependencies
* [nerves_system_br: bump to v1.12.4](https://github.com/nerves-project/nerves_system_br/releases/tag/v1.12.4)
* [Erlang/OTP 23.0.3](https://erlang.org/download/OTP-23.0.3.README)
* [nerves_heart v0.3.0](https://github.com/nerves-project/nerves_heart/releases/tag/v0.3.0)
* New features
* The `/data` directory now exists for storing application-specific data. It
is currently a symlink to `/root`. Using `/data` will eventually be
encouraged over `/root` even though currently there is no advantage. This
change makes it possible to start migrating paths in applications and
libraries.
* Fixes
* Fixed old references to the `-Os` compiler flag. All C/C++ code will default
to using `-O2` now.
## v2.7.1
* Fixes
* Remove `nerves_system_linter` from hex package. This fixes mix dependency
errors in projects that reference systems with different
`nerves_system_linter` dependency specs.
## v2.7.0
This release updates the system to use Buildroot 2020.05 and Erlang/OTP 23.
Please see the respective release notes for updates and deprecations in both
projects for changes that may affect your application.
* New features
* Enable WiFi mesh support in the 802.11 stack
* NervesKey support (see README.md for device tree overlay information)
* Updated dependencies
* [nerves_system_br v1.12.0](https://github.com/nerves-project/nerves_system_br/releases/tag/v1.12.0)

* Linux 4.19.120 with Beagleboard kernel patches
## v2.6.2
* Updated dependencies
* [nerves_system_br v1.11.4](https://github.com/nerves-project/nerves_system_br/releases/tag/v1.11.4)
* Erlang 22.3.4.1
* fwup 1.7.0
## v2.6.1
* Updated dependencies
* [nerves_system_br v1.11.2](https://github.com/nerves-project/nerves_system_br/releases/tag/v1.11.2)
* Erlang 22.3.1
* erlinit 1.7.0 - tty initialization support
* fwup 1.6.0 - xdelta3/VCDIFF patch support
* Enable unixodbc so that Erlang's odbc application can be used in projects
## v2.6.0
This release updates Buildroot to 2020.02 and upgrades gcc from 8.3 to 9.2.
While this is a minor version bump due to the Buildroot release update, barring
advanced usage of Nerves, this is a straightforward update from v2.5.2.
* Updated dependencies
* [nerves_system_br v1.11.0](https://github.com/nerves-project/nerves_system_br/releases/tag/v1.11.0)
* linux 4.19.103 with Beagleboard kernel patches(bone40)
* Erlang 22.2.8
## v2.5.2
* Fixes
* This fixes a regression on OSX where the USB gadget Ethernet would
incorrectly try to go into RNDIS mode and not work. Gadget Ethernet works
with this fix on Linux and OSX. It also works on Windows with a driver
installed. See the README.md for details.
* The USB driver uses PIO mode again. It had mistakenly been switched to DMA
mode. DMA mode works for a lot of USB devices, but not all and it's not what
Debian does. See [PR
138](https://github.com/nerves-project/nerves_system_bbb/pull/138) for more
information.
* Updated dependencies
* [nerves_system_br v1.10.2](https://github.com/nerves-project/nerves_system_br/releases/tag/v1.10.2)
* Erlang 22.2.4
## v2.5.1
This release changes the behavior of the gadget port. The gadget driver has been changed to use g_ether. This
provides a more stable network connection at the expense of the virtual serial
port.
* Enhancements
* Set `expand=true` on the application data partition. This will only take
effect for users running the complete task, fwup will not expand application
data partitions that exist during upgrade tasks.
* linux: swap the cdc composite gadget for g_ether
* Updated dependencies
* [nerves_system_br v1.10.1](https://github.com/nerves-project/nerves_system_br/releases/tag/v1.10.1)
* Erlang 22.2.3
## v2.5.0
This release updates Buildroot to 2019.11 with security and bug fix updates
across Linux packages. Enables dnsd, udhcpd and ifconfig in the default
Busybox configuration to support `vintage_net` and `vintage_net_wizard`.
See the `nerves_system_br` notes for details.
* Updated dependencies
* [nerves_system_br v1.10.0](https://github.com/nerves-project/nerves_system_br/releases/tag/v1.10.0)
* Erlang 22.1.8
* Linux 4.19.72 with the Beagleboard Debian kernel patches
## v2.4.2
This release updates Buildroot to 2019.08.2 with security and bug fix updates
across Linux packages. See the `nerves_system_br` notes for details.
Erlang/OTP is now at 22.1.7.
This release also enables the pinmux helper for changing the pin settings on
the PocketBeagle and other boards.
For example:
```bash
iex> cat "/sys/devices/platform/ocp/ocp:P2_30_pinmux/state"
default
iex> File.write("/sys/devices/platform/ocp/ocp:P2_30_pinmux/state", "spi_cs")
:ok
```
For the PocketBeagle, see
https://github.com/beagleboard/linux/blob/4.19/arch/arm/boot/dts/am335x-pocketbeagle.dts#L1186
* Updated dependencies
* [nerves_system_br v1.9.5](https://github.com/nerves-project/nerves_system_br/releases/tag/v1.9.5)
## v2.4.1
This release pulls in security and bug fix updates from `nerves_system_br`.
Erlang/OTP is now at 22.1.1.
* Updated dependencies
* [nerves_system_br v1.9.4](https://github.com/nerves-project/nerves_system_br/releases/tag/v1.9.4)
* bborg-overlays - update to latest to pull in device tree overlay fixes and
additions from upstream
## v2.4.0
This release updates Buildroot to 2019.08 with security and bug fix updates
across Linux packages. See the `nerves_system_br` notes for details.
* Updated dependencies
* [nerves_system_br v1.9.2](https://github.com/nerves-project/nerves_system_br/releases/tag/v1.9.2)
* Enhancements
* Support a variety of USB->UART adapters so more devices work out-of-the-box
## v2.3.2
This release fixes an issue where the MAC address for the wired Ethernet port on
many BeagleBone-based boards was not being set. Unfortunately, the fix is with
the U-Boot bootloader configuration and this is not updated when applying
updates over-the-air. Fresh firmware installs will apply the fix, so if you're
burning MicroSD cards, you're fine. It is possible to fix the wired Ethernet MAC
address issue in the field if necessary. Please post to our support channels if
you need to do this and are not sure.
* Updated dependencies

* Updated dependencies
* [nerves_system_br v1.5.3](https://github.com/nerves-project/nerves_system_br/releases/tag/v1.5.3)
## v2.0.0-rc.0
This is a backwards incompatible update to `nerves_system_bbb`. Over-the-air
updates to existing devices will not work. If you're a production user of
`nerves_system_bbb`, please consider supporting efforts to maintain a v1.4.0
branch.
The v2.0.0 support adds the following:
1. Device tree overlays are applied by U-Boot now. Support in Nerves is nearly
identical to Beagleboard.org's Debian distribution. This fixes significant
issues in v1.4.0 and before ever since upstream moved from loading device
tree overlays in Linux to U-Boot.
2. Support for automatic failback of bad new builds. If enabled, your Nerves
application will need to mark a software update as good (for example, it can
contact a server) or else the next reboot will revert.
3. The application partition uses F2FS rather than EXT4. This noticeably
improves startup time on the first boot and has some less obvious advantages
from being a Flash-aware file system.
4. The hardware watchdog is enabled at boot. Your application must enable
`heart` now.
5. The U-Boot environment was increased in size to 128 KB. This was required for
the new device tree overlay support and unfortunately makes migrating devices
from v1.4.0 not possible without significant work.
* Updated dependencies
* [nerves_system_br v1.5.2](https://github.com/nerves-project/nerves_system_br/releases/tag/v1.5.2)
* Linux 4.18.9 + The Beagleboard Debian kernel patches
* Erlang 21.0.9
## v1.4.0
This release contains various updates to provisioning variables and data.
**Host requirements**
Building firmware using this system requires `fwup` to be updated on your
host computer to at least `v1.2.5`. The target minimum version requirement
has not changed from `0.15.0`.
**Serial numbers**
Device serial numbers are now set using `NERVES_SERIAL_NUMBER` instead of
`SERIAL_NUMBER`. This is to reduce ambiguity on the source of the serial
by name spacing it along side other Nerves variables. The U-Boot environment
key has also changed from `serial_number` to `nerves_serial_number`. The
erlinit.config has been updated to provide backwards compatibility for setting
the hostname from the serial number by checking for `nerves_serial_number`
and falling back to `serial_number`.
**Custom provisioning**
Provisioning data is applied at the time of calling the `fwup` task `complete`.
The `complete` task is executed when writing the firmware to the target disk.
During this time, `fwup` will include the contents of a provisioning file
located at `${NERVES_SYSTEM}/images/fwup_include/provisioning.conf`. By default,
this file only sets `nerves_serial_number`. You can add additional provisioning
data by overriding the location of this file to include your own by setting
the environment variable `NERVES_PROVISIONING`. If you override this variable
you will be responsible for also setting `nerves_serial_number`.

also has a configuration change to the Linux kernel that enables scaling the
processor frequency based on workload. This makes the process run much cooler
while still allowing it to increase frequency for heavy computations.
Note that the trivial `.fw` files are no longer created by CI scripts. If you've
forked this project and are building systems using CI, make sure to update your
publish scripts.

## v0.16.1
* Updated dependencies
* nerves_system_br v0.13.7
## v0.16.0
This release contains an updated toolchain with Linux 4.1 Headers.
You will have to clean and compile any c/c++ code in your project and
dependencies. Failure to do so will result in an error when producing firmware.
* nerves_system_br v0.13.5
* fwup 0.15.4
* Nerves toolchain v0.11.0
## v0.15.0
* nerves_system_br v0.13.3
* erlinit 1.1.4
* New features
* Firmware updates verify that they're updating the right target. If the target
doesn't say that it's an `bbb` through the firmware metadata, the update
will fail.
* Added meta-misc and meta-vcs-identifier to the `fwup.conf` metadata for use
by users and for the regression test framework
* Use String.trim instead of String.strip to silence Elixir 1.5 warnings
## v0.14.0
* nerves_system_br v0.13.2
* OTP 20
* erlinit 1.1.3
* fwup 0.15.3
## v0.13.0
This release is NOT backwards compatible with previous releases and will not
upgrade old systems. With work, it is possible to upgrade old systems, but it is
not recommended.
* nerves_system_br v0.12.1
* erlinit 1.1.1
* fwup 0.15.0
* New features
* The application data partition is now `ext4`. This greatly improves its
robustness to corruption. Nerves.Runtime contains code to initialize it on
first boot.
* Firmware images now contain metadata that can be queried at runtime (see
Nerves.Runtime.KV
* The boot partition is managed in an A/B style to support more robust
firmware updates.
* Bug fixes
* The Linux kernel is no longer compiled for SMP. All Beaglebone variants
are single processor.
NOTE: It is possible to support "failback" operation of firmware updates with
the BBB. I.e. if an partition doesn't boot, the system reverts to the previous
one. This is not implemented here, but this system is being made to align more
with implementations that do this to make the transition easier.
## v0.12.0
* nerves_system_br v0.10.0
* Buildroot 2017.02
* Erlang/OTP 19.3
* New features
* Support for BBG Wireless - the BBGW's MAC Address is not automatically set
so support needs to be added. However, one BBGW on a WLAN works.
* Bump Linux kernel to 4.4.60
## v0.11.0
* New Features
* Support for Nerves 0.5.0
## v0.10.0
* New features
* Bump toolchain to use gcc 5.3 (previously using gcc 4.9.3)
* Bump Linux kernel to 4.4.43
## v0.9.0
This version switches to using the `nerves_package` compiler. This will
consolidate overall deps and compilers.
* Nerves.System.BR v0.8.1
* Support for distillery
* Support for nerves_package compiler
## v0.8.0
When upgrading to this version, be sure to review the updates to
nerves_defconfig. BR2_PACKAGE_ERLANG is no longer selected automatically and
must be added.
* nerves_system_br v0.7.0
* Package updates
* Buildroot 2016.08
* Bug fixes
* Many packages were removed. These include Elixir and LFE since neither are
actually used. Both are added as part of the user build step, so no
functionality is lost. The most visible result is that the system images
are smaller and the test .fw file boots to the Erlang prompt.
* Fix false positive from scrubber when checking executable formats due to
C++ template instantiations. Ignores SYSV vs. GNU/Linux ABI difference.
## v0.7.1
* Package versions
* Nerves.System.BR v0.6.1
* New features
* Pull in BeagleBone Green updates (new u-boot, bbg device tree)
## v0.7.0
* Nerves.System.BR v0.6.0
* Package updates
* Erlang OTP 19
* Elixir 1.3.1
* fwup 0.8.0
* erlinit 0.7.3
* bborg-overlays (pull in I2C typo fix from upstream)
* Bug fixes
* Synchronize file system kernel configs across all platforms
## v0.6.2
* Bug Fixes
* Enabled bbborg-overlays for universal device tree
## v0.6.1
* Nerves.System.BR v0.5.1
* Bug Fixes(nerves-env)
* Added include paths to CFLAGS and CXXFLAGS
* Pass sysroot to LDFLAGS
## v0.6.0
* Nerves.System.BR v0.5.0
* New features
* WiFi drivers enabled by default on RPi2 and RPi3
* Include wireless regulatory database in Linux kernel by default
on WiFi-enabled platforms. Since kernel/rootfs are read-only and
coupled together for firmware updates, the normal CRDA/udev approach
isn't necessary.
* Upgraded the default BeagleBone Black kernel from 3.8 to 4.4.9. The
standard BBB device tree overlays are included by default even though the
upstream kernel patches no longer include them.
* Change all fwup configurations from two step upgrades to one step
upgrades. If you used the base fwup.conf files to upgrade, you no
longer need to finalize the upgrade. If not, there's no change.
## v0.5.0
* Nerves.System.BR v0.4.1
* Bug fixes
* syslinux fails to boot when compiled on some gcc 5 systems
* Fixed regression when booting off eMMC on the BBB
* Package updates
* Erlang 18.3
* Elixir 1.2.5
* Enhancements
* Includes config-pin for controlling pin muxing. See [beaglebone-universal-io](https://github.com/cdsteinkuehler/beaglebone-universal-io)
