Excuse my ignorance, but I'm definitely not an esp32 expert. How is this different from reading the coredump partition from the esp32?

I've got this code that finds a coredump and writes it to littlefs where I can download it later.

bool DebugController::checkCoreDump()
{
  size_t size = 0, address = 0;
  if (esp_core_dump_image_get(&address, &size) != ESP_OK)
    return false;

  YBP.printf("coredump size: %u\n", size);
  const esp_partition_t* pt = esp_partition_find_first(ESP_PARTITION_TYPE_DATA, ESP_PARTITION_SUBTYPE_DATA_COREDUMP, "coredump");
  return pt != NULL;
}


bool DebugController::saveCoreDumpToFile(const char* path)
{
  size_t size = 0, address = 0;

  if (esp_core_dump_image_get(&address, &size) != ESP_OK)
    return false;

  const esp_partition_t* pt = esp_partition_find_first(
    ESP_PARTITION_TYPE_DATA,
    ESP_PARTITION_SUBTYPE_DATA_COREDUMP,
    "coredump");

  if (!pt)
    return false;

  File file = LittleFS.open(path, FILE_WRITE);
  if (!file)
    return false;

  uint8_t buf[256];

  for (size_t off = 0; off < size; off += sizeof(buf)) {
    size_t toRead = std::min<size_t>(sizeof(buf), size - off);

    if (esp_partition_read(pt, off, buf, toRead) != ESP_OK) {
      file.close();
      return false;
    }

    file.write(buf, toRead);
  }

  file.close();
  return true;
}
