🔥 Removed

  • Removed support for Zephyr < 2.7.0
  • Removed support for nRF-Connect SDK < 1.9.2
  • Removed support for ESP-IDF < 4.4.0

Please contact us if you need support for
earlier versions!

🐛 Fixed

  • General:

    • Correct an issue where eMemfaultRebootReason is expressed as a 4-byte type
      instead of 2-bytes when compiling with Clang with high optimization, when
      targeting ARM. This results in Coredumps tagged as Unknown instead of the
      correct reason code.

📈 Added

  • General:

    • Add a pair of optional user-provided functions,
      memfault_reboot_tracking_load() / memfault_reboot_tracking_save(), to
      allow users to provide their own implementations for saving and loading
      reboot tracking data. This is useful when the default implementation is not
      suitable for the platform or when the user wants to store the data in a
      different location.

    • The
      Stable Sessions Device Vital
      added in SDK version 1.15.0 is fully available and no longer considered
      experimental.

    • Add an optional memfault_port_coredump_save_begin() callback, for use by
      Memfault ports. This allows memfault_platform_coredump_save_begin() to be
      implemented by the platform instead, for custom pre-coredump operations.
      Thanks to @finger563 for reporting this issue in
      #77!

    • Improved API docs for events and data packetizer components by noting
      restrictions for use in ISR contexts

  • Zephyr:

    • Update the Qemu app to support the nucleo_l496zg board, with support for
      the Zephyr bbram subsystem, and implement the new
      memfault_reboot_tracking_load() / memfault_reboot_tracking_save()
      functions to demonstrate the functionality.

  • ESP-IDF:

    • New Kconfig setting, CONFIG_MEMFAULT_ENABLE_REBOOT_DIAG_DUMP, to print the
      ESP-IDF reboot reason code on system boot, for debugging purposes. This
      feature is disabled by default.

🛠️ Changed

  • General:

    • Update support links to refer to the preferred site
      https://mflt.io/contact-support instead of the Memfault support email.
      This link will redirect to a form where questions can be sent to the
      Memfault support team.

  • nRF-Connect SDK:

    • Changed the Kconfig symbol MEMFAULT_REBOOT_REASON_GET_CUSTOM to be imply
      instead of select when the nRF-Connect SDK is enabled. This permits users
      to disable the nrfx-based reboot reason tracking if needed.
