1.22.0

📈 Added

• General

  • Enable building the SDK on aarch64. Note that this only adds support for
    building the SDK on that target, full end-to-end support is not yet
    available.

• Zephyr:

  • For SOC's with a data cache, flush the cache prior to performing a system
    reboot, to ensure data integrity of the RAM-backed reboot tracking data.
    This is added to the memfault_platform_reboot() default implementation,
    which can be overridden by the user if needed.

    SOC's without a cache will have no effect from this change.

🛠️ Changed

• General:

  • MEMFAULT_LOG_TIMESTAMPS_ENABLE is now enabled by default. When enabled,
    and memfault_platform_time_get_current() returns a valid timestamp, logs
    will include a second-precision timestamp. This applies to both:

    • logs captured as part of a coredump
    • logs sent to Memfault after invoking memfault_log_trigger_collection()

  • Remove some 64-bit integer divides used when computing the built-in
    uptime_s metric, and in the FreeRTOS
    memfault_platform_get_time_since_boot_ms() implementation.

• ESP-IDF:

  • Log lines that are only a single '\n' character are no longer recorded in
    the Memfault Log Buffer.

🚩 Deprecated

🔥 Removed

🐛 Fixed

• Zephyr:

  • The hwinfo-based Reset Reason implementation did not clear the reset
    reason register after reading the data. Updated to properly call
    hwinfo_clear_reset_cause() after reading the reset reason.
