1.13.0

📈 Added

• FreeRTOS:

  • The SDK now has a config to control whether to split CPU usage per core when
    building for a multi-core device. Enable this setting by adding
    #define MEMFAULT_FREERTOS_RUNTIME_STATS_MULTI_CORE_SPLIT 1 to
    memfault_platform_config.h. This setting is disabled by default.

• ESP-IDF:

  • Added a Kconfig, CONFIG_MEMFAULT_FREERTOS_RUNTIME_STATS_MULTI_CORE_SPLIT,
    to control MEMFAULT_FREERTOS_RUNTIME_STATS_MULTI_CORE_SPLIT. This Kconfig
    is enabled by default for multi-core devices.

🛠️ Changed

• FreeRTOS:

  • Changed previous idle task run time percent metrics to measure CPU usage
    (i.e. the complement of the idle task run time)
  • Renamed the following metrics:
    • Single-Core + Multi-Core Default:
      • idle_task_run_time_percent -> cpu_usage_pct
    • Multi-Core Split:
      • idle0_task_run_time_percent -> cpu_usage_pct
      • idle1_task_run_time_percent -> cpu1_usage_pct

• ESP-IDF:

  • Unknown or unclassified reboot reason codes returned by get_reset_reason()
    are now correctly recorded as kMfltRebootReason_Unknown instead of
    kMfltRebootReason_UnknownError (UnknownError is reserved for an
    "unexpected" reboot path, where Unknown is used when the reboot reason
    cannot be determined).
