Changelog

v1.7.2

  • Bux fixes
    • Add TAR option --no-same-owner to fix errors when untarring artifacts as the root user.
  • Updated dependencies

v1.7.1

  • Improvements

    • Bump C compiler options to -O2 from -Os. This provides a small, but measurable performance improvement (500ms at boot in a trivial project tested on nerves_system_rpi0).

  • Updated dependencies

v1.7.0

v1.6.3

v1.6.2

v1.6.1

  • Updated dependencies

  • Enhancements

    • Moved boardid config from inside erlinit.config to /etc/boardid.config

v1.6.0

This pulls in a pending patch in Buildroot to update the version of OpenSSL from 1.0.2 to 1.1.0h. This fixes what appears to be issues with Erlang using OpenSSL engines. It also enables Erlang crypto algorithms such as ed25519 that have been added in recent Erlang releases.

v1.5.1

v1.5.0

This release updates the Linux kernel from 4.13 to 4.18.9.

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.

v1.3.0

This release upgrades gcc from version 6.3.0 to 7.3.0. See the toolchain release notes for more information.

v1.2.1

v1.2.0

This release updates Erlang to OTP 21.0

v1.1.1

This release fixes some issues and adds firmware UUID support. This support can be used to unambiguously know what's running on a device.

  • Updated dependencies

  • Bug fixes

    • Empty serial numbers stored in the U-Boot environment would be used instead of reverting to devices IDs built into the CPU or board.
    • It wasn't possible to enable QtWebEngine (needed for kiosk apps)

v1.1.0

This release adds official support for provisioning serial numbers to devices. Other information can be provisioned in a similar manner. See the README.md for details.

Buildroot was also updated to 2018.05. Be sure to review the nerves_system_br link for the changes in the embedded Linux components.

v1.0.0

This release is nearly identical to rc.1 except with the deps bump to 1.0 and documentation/comment updates.

v1.0.0-rc.1

This release contains updates to Erlang and heart from nerves_system_br and mostly cosmetic changes to this project. 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.

v1.0.0-rc.0

v0.5.0

v0.4.1

  • Updated dependencies

  • Changes

    • Temporarily disable the system linter since it fails and the fix requires some time.

v0.4.0

  • Updated dependencies

  • Enhancements

    • Increased memory in qemu script to 1 GB. 128 MB works, but can cause some apps to reboot with out of memory errors.

    • Start running nerves_system_linter to check for configuration errors.

    • Automount the boot partition readonly at /boot

    • Support for reverting firmware.

      See Reverting Firmware for more info on reverting firmware.

      See fwup-revert.conf for more information on how fwup handles reverting.

v0.3.2

v0.3.1

v0.3.0

  • Updated dependencies
  • Enhancements
    • erlinit added aliased /dev/rootdisk* for referencing the boot disk. See the readme for more info.
    • Updated nerves to 0.8. Move nerves.exs into mix.exs

v0.2.1

v0.2.0

v0.1.0

  • Initial release
