@memfault-bot memfault-bot released this 27 Oct 16:10
1.30.3
67244e0

This is a patch release, fixing build errors and one bug.

🛠️ Changed

  • Zephyr:

    • Update the RRAM coredump storage backend implementation to support the
      Nordic nRF54LM20 (and other Nordic nRF54L series chips) when not using
      partition manager to assign flash regions (i.e. using device tree fixed
      partitions). See
      ports/zephyr/common/memfault_rram_backed_coredump.c
      for details, and how to enable the coredump storage backend.

    • Fix a compilation error when CONFIG_MEMFAULT_METRICS_THREADS_DEFAULTS=n.

    • Remove an error log statement from
      memfault_platform_thread_metrics.c.
      Previously this would log as
      <err> mflt: No thread name registered for 0x2000eae8, for example, but was
      not useful in many cases, and is not an error in any case.

🐛 Fixed

  • ESP-IDF:

    • Fix a compilation issue when building the ESP32 sample app
      for an ESP32-C6 with MEMFAULT_DISABLE= set (i.e.
      MEMFAULT_DISABLE=1 idf.py set-target esp32c6 build). This only impacts the
      sample application.

  • Zephyr:

    • Disable invoking LOG_PANIC() during fault handling by default. When
      deferred logging is used (CONFIG_LOG_MODE_DEFERRED=y), triggering a panic
      flush from fault context may result in some log backends
      (CONFIG_SHELL_LOG_BACKEND for example) to double-fault, which results in
      failed coredump captures. This specifically can happen when running a
      non-secure application with TF-M, and passing back from a secure fault
      handler using CONFIG_TFM_ALLOW_NON_SECURE_FAULT_HANDLING=y. Users who are
      comfortable enabling this can re-enable LOG_PANIC() with
      CONFIG_MEMFAULT_FAULT_HANDLER_LOG_PANIC=y.

    • Remove an unnecessary depends on PARTITION_MANAGER_ENABLED in the
      MEMFAULT_COREDUMP_STORAGE_RRAM Kconfig setting. This feature only requires
      a partition labeled memfault_coredump_partition, but does not require
      partition manager specifically (which is a Nordic nRF-Connect SDK feature,
      not a Zephyr feature). Thanks to
      @JordanYates for reporting this issue in
      #96!
