Can only be enabled if there is no SPIRAM configured. This option will power down flash under a strict but relatively safe condition. Also, it is possible to power down flash under a relaxed condition by using esp_sleep_pd_config() to set ESP_PD_DOMAIN_VDDSDIO to ESP_PD_OPTION_OFF. It should be noted that there is a risk in powering down flash, you can refer `ESP-IDF Programming Guide/API Reference/System API/Sleep Modes/Power-down of Flash` for more details. config ESP_SLEEP_FLASH_LEAKAGE_WORKAROUND bool "Pull-up Flash CS pin in light sleep" depends on !APP_BUILD_TYPE_PURE_RAM_APP && !ESP_SLEEP_POWER_DOWN_FLASH default y help All IOs will be set to isolate(floating) state by default during sleep. Since the power supply of SPI Flash is not lost during lightsleep, if its CS pin is recognized as low level(selected state) in the floating state, there will be a large current leakage, and the data in Flash may be corrupted by random signals on other SPI pins. Select this option will set the CS pin of Flash to PULL-UP state during sleep, but this will increase the sleep current about 10 uA. If you are developing with esp32xx modules, you must select this option, but if you are developing with chips, you can also pull up the CS pin of SPI Flash in the external circuit to save power consumption caused by internal pull-up during sleep. (!!! Don't deselect this option if you don't have external SPI Flash CS pin pullups.) config ESP_SLEEP_PSRAM_LEAKAGE_WORKAROUND bool "Pull-up PSRAM CS pin in light sleep" depends on SPIRAM default y help All IOs will be set to isolate(floating) state by default during sleep. Since the power supply of PSRAM is not lost during lightsleep, if its CS pin is recognized as low level(selected state) in the floating state, there will be a large current leakage, and the data in PSRAM may be corrupted by random signals on other SPI pins.

CPU will run rom code (deepsleep) or ram code (lightsleep) first, and then load or execute code from flash. Some flash chips need sufficient time to pass between power on and first read operation. By default, without any extra delay, this time is approximately 900us, although some flash chip types need more than that. (!!! Please adjust this value according to the Data Sheet of SPI Flash used in your project.) In Flash Data Sheet, the parameters that define the Flash ready timing after power-up (minimum time from Vcc(min) to CS activeare) usually named tVSL in ELECTRICAL CHARACTERISTICS chapter, and the configuration value here should be: ESP_SLEEP_WAIT_FLASH_READY_EXTRA_DELAY = tVSL - 900 For esp32 and esp32s3, the default extra delay is set to 2000us. When optimizing startup time for applications which require it, this value may be reduced. If you are seeing "flash read err, 1000" message printed to the console after deep sleep reset on esp32, or triggered RTC_WDT/LP_WDT after lightsleep wakeup, try increasing this value. (For esp32, the delay will be executed in both deep sleep and light sleep wake up flow. For chips after esp32, the delay will be executed only in light sleep flow, the delay controlled by the EFUSE_FLASH_TPUW in ROM will be executed in deepsleep wake up flow.) config ESP_SLEEP_DEBUG bool "esp sleep debug" default n help Enable esp sleep debug. config ESP_SLEEP_GPIO_ENABLE_INTERNAL_RESISTORS bool "Allow to enable internal pull-up/downs for the Deep-Sleep wakeup IOs" default y help When using rtc gpio wakeup source during deepsleep without external pull-up/downs, you may want to make use of the internal ones. config ESP_SLEEP_EVENT_CALLBACKS bool "Enable registration of sleep event callbacks" depends on FREERTOS_USE_TICKLESS_IDLE default n help If enabled, it allows user to register sleep event callbacks. It is primarily designed for internal developers and customers can use PM_LIGHT_SLEEP_CALLBACKS as an alternative. NOTE: These callbacks are executed from the IDLE task context hence you cannot have any blocking calls in your callbacks. NOTE: Enabling these callbacks may change sleep duration calculations based on time spent in callback and hence it is highly recommended to keep them as short as possible. config ESP_SLEEP_CACHE_SAFE_ASSERTION bool "Check the cache safety of the sleep wakeup code in sleep process" default n select ESP_PANIC_HANDLER_IRAM help Enabling it will check the cache safety of the code before the flash power is ready after light sleep wakeup, and check PM_SLP_IRAM_OPT related code cache safety.

However, this feature is only supported on the ESP32. The ESP32 uses the internal 8MHZ as a reference when estimating.
