@@ -193,7 +193,7 @@ The following options will reduce IRAM usage of some ESP-IDF features:
- Refer to the sdkconfig menu ``Auto-detect Flash chips``, and you can disable flash drivers which you do not need to save some IRAM.
:SOC_GPSPI_SUPPORTED: - Enable :ref:`CONFIG_HEAP_PLACE_FUNCTION_INTO_FLASH`. Provided that :ref:`CONFIG_SPI_MASTER_ISR_IN_IRAM` is not enabled and the heap functions are not incorrectly used from ISRs, this option is safe to enable in all configurations.
:esp32c2: - Enable :ref:`CONFIG_BT_RELEASE_IRAM`. Release BT text section and merge BT data, bss & text into a large free heap region when ``esp_bt_mem_release`` is called. This makes Bluetooth unavailable until the next restart, but saving ~22 KB or more of IRAM.
- Disable :ref:`CONFIG_LIBC_LOCKS_PLACE_IN_IRAM` if no ISRs that run while cache is disable (i.e. IRAM ISRs) are using libc lock APIs.
- Disable :ref:`CONFIG_LIBC_LOCKS_PLACE_IN_IRAM` if no ISRs that run while cache is disabled (i.e. IRAM ISRs) use libc lock APIs.

- 要禁用不需要的 flash 驱动程序，节省 IRAM 空间，请参阅 sdkconfig 菜单中的 ``Auto-detect Flash chips`` 选项。
:SOC_GPSPI_SUPPORTED: - 启用 :ref:`CONFIG_HEAP_PLACE_FUNCTION_INTO_FLASH`。只要未启用 :ref:`CONFIG_SPI_MASTER_ISR_IN_IRAM` 选项，且没有从 ISR 中错误地调用堆函数，就可以在所有配置中安全启用此选项。
:esp32c2: - 启用 :ref:`CONFIG_BT_RELEASE_IRAM`。 蓝牙所使用的 data，bss 和 text 段已经被分配在连续的RAM区间。当调用 ``esp_bt_mem_release`` 时，这些段都会被添加到 Heap 中。 这将节省约 22 KB 的 RAM。但要再次使用蓝牙功能，需要重启程序。
- 禁用 :ref:`CONFIG_LIBC_LOCKS_PLACE_IN_IRAM`。若在缓存禁用的情况下，运行中的中断服务程序（即 IRAM ISR）没有使用 libc 锁 API，那么禁用该配置可以节省 IRAM 空间。
