ESP-IDF esp_partition_read esp_partition_erase_range thread safe flash operation lock concurrent read erase official documentation
💡 Result:
**The flash driver serializes access to the hardware, but that does not make a multi-call read/erase sequence atomic.**
- `esp_partition_read()` and `esp_partition_erase_range()` are partition-bounded wrappers around lower-level flash operations. ([docs.espressif.com](https://docs.espressif.com/projects/esp-idf/en/latest/esp32s31/api-reference/storage/partition.html?utm_source=openai))
- The current SPI Flash guide says flash APIs are **not atomic**: when a write overlaps an in-progress read, the read may return a mixture of old and updated data. ([docs.espressif.com](https://docs.espressif.com/projects/esp-idf/en/stable/esp32/api-reference/peripherals/spi_flash/index.html?utm_source=openai))
- The driver source shows internal locking around flash access, but erase releases/reacquires access between erase chunks. That prevents unsafe simultaneous hardware use; it does **not** guarantee a consistent snapshot across concurrent operations on the same region. ([github.com](https://github.com/espressif/esp-idf/blob/master/components/spi_flash/spi_flash_os_func_app.c?utm_source=openai))
**Practical takeaway:** concurrent calls can use the driver’s internal synchronization, but if one task must not read a region while another task erases or modifies it—or you need an erase-plus-write sequence to be indivisible—coordinate those tasks with your own mutex or other application-level protocol. The docs specifically describe read/write overlap, not a precise read-versus-erase result; treat overlapping access as requiring coordination.
These sources are the current/latest ESP-IDF documentation and `master` source found; behavior can depend on ESP-IDF version and target.

pioarduino platform-espressif32 55.03.311 ESP-IDF version spi_flash erase read locking
💡 Result:
`pioarduino/platform-espressif32` **55.03.311** bundles Arduino-ESP32 **3.3.11**, based on **ESP-IDF 5.5.5**. (GitHub issue 12899 in espressif/arduino-esp32 (link omitted to avoid creating a cross-reference))
For that IDF generation, the usual APIs are `esp_flash_read()` and `esp_flash_erase_region()` (or the higher-level `esp_partition_read()` / `esp_partition_erase_range()` when accessing a partition on the main flash). Reads don’t require alignment; erase start and length must be sector-aligned—typically 4 KiB. ([docs.espressif.com](https://docs.espressif.com/projects/esp-idf/en/release-v5.5/esp32/api-reference/peripherals/spi_flash/index.html?utm_source=openai))
**Locking:** ESP-IDF’s flash API provides internal locking; its documentation describes a mutex protecting flash operations, plus coordination around cache/bus access. Flash calls are **not atomic as a group**: overlapping read and write operations can return mixed old/new data. If you need a multi-call sequence to be indivisible relative to other tasks, the cited API page does not establish that ordinary calls provide such transaction-level locking. ([docs.espressif.com](https://docs.espressif.com/projects/esp-idf/en/release-v5.5/esp32/api-reference/peripherals/spi_flash/index.html?utm_source=openai))
The locking details above are from ESP-IDF’s **release-v5.5** documentation, not a direct inspection of the exact `55.03.311` bundled source, so minor packaging-specific differences remain unverified.

<|OPENAI|analysis 代期特码>読み取り判定と更新開始を同じ同期で保護してください。
readAt() は slotBeingUpdated を確認した後に HalOtaSlot::read() を呼びます。この間に更新タスクがフラグを設定して消去を完了すると、読み取りは消去済みまたは更新途中のデータを成功扱いで取得できます。
ESP-IDF は個々の flash 操作を直列化しますが、読み取りと更新の複数操作を原子的には扱いません。SdCardFont::read() は読み取り失敗時だけ SD にフォールバックするため、不整合なデータを返す読み取りを検出できません。
読み取りの flag 判定から slot.read() 完了までと、更新側の無効化および消去を、同じ同期機構で保護してください。
