CrashStorage

The CrashStorage class extends the Storage class to log crash information specifically for the ESP8266 platform. It captures reset information and stack traces to aid in debugging and post-mortem analysis.

Constructor and Destructor:

  • CrashStorage(const String &path) Constructs a CrashStorage instance with a specified file path.

  • virtual ~CrashStorage() Destructor that ensures proper cleanup.

Methods:

  • bool store() override Stores the crash data to the specified file.

  • bool clean() override Cleans the crash data by resetting crash information and removing the file.

  • bool printCrashDataIfExists() const Prints the crash data to the serial console if it exists.

Protected Members:

  • CBORObject mCbor (inherited from Storage via CBORStorage): Manages structured CBOR data for crash information.

  • struct rst_info *mResetInfo Pointer to the reset information structure containing details about the crash.

  • uint32_t mStackStart Starting address of the stack trace.

  • uint32_t mStackEnd Ending address of the stack trace.

Private Members:

  • void setCrashInfo(struct rst_info* resetInfo, uint32_t stackStart, uint32_t stackEnd) Sets the crash information for logging.

    • resetInfo (struct rst_info*): Pointer to the reset information structure.

    • stackStart (uint32_t): Starting address of the stack trace.

    • stackEnd (uint32_t): Ending address of the stack trace.

  • Bytes buildDumpData() const Constructs the crash dump data from the reset information and stack trace.
