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_RTC_BUS_ISO_WORKAROUND bool default y if IDF_TARGET_ESP32 || IDF_TARGET_ESP32S2 || IDF_TARGET_ESP32S3 config ESP_SLEEP_GPIO_RESET_WORKAROUND bool "light sleep GPIO reset workaround" default y if IDF_TARGET_ESP32C3 || IDF_TARGET_ESP32S3 || IDF_TARGET_ESP32H2 select PM_SLP_DISABLE_GPIO if FREERTOS_USE_TICKLESS_IDLE help esp32c3, esp32s3 and esp32h2 will reset at wake-up if GPIO is received a small electrostatic pulse during light sleep, with specific condition - GPIO needs to be configured as input-mode only - The pin receives a small electrostatic pulse, and reset occurs when the pulse voltage is higher than 6 V For GPIO set to input mode only, it is not a good practice to leave it open/floating, The hardware design needs to controlled it with determined supply or ground voltage is necessary. This option provides a software workaround for this issue. Configure to isolate all GPIO pins in sleep state. config ESP_SLEEP_PSRAM_LEAKAGE_WORKAROUND bool "PSRAM leakage current workaround in light sleep" depends on SPIRAM default y help When the CS pin of SPIRAM is not pulled up, the sleep current will increase during light sleep. If the CS pin of SPIRAM has an external pull-up, you do not need to select this option, otherwise, you should enable this option. config ESP_SLEEP_FLASH_LEAKAGE_WORKAROUND bool "Flash leakage current workaround in light sleep" default y help When the CS pin of Flash is not pulled up, the sleep current will increase during light sleep. If the CS pin of Flash has an external pull-up, you do not need to select this option, otherwise, you should enable this option. config ESP_SLEEP_MSPI_NEED_ALL_IO_PU bool "All pins of mspi need pull up" depends on ESP_SLEEP_PSRAM_LEAKAGE_WORKAROUND || ESP_SLEEP_FLASH_LEAKAGE_WORKAROUND default y if IDF_TARGET_ESP32S3 help To reduce leakage current, some types of SPI Flash/RAM only need to pull up the CS pin during light sleep. But there are also some kinds of SPI Flash/RAM that need to pull up all pins. It depends on the SPI Flash/RAM chip used. endmenu menu "RTC Clock Config" # This is used for configure the RTC clock. config RTC_CLOCK_BBPLL_POWER_ON_WITH_USB bool "Keep BBPLL clock always work" depends on ESP_CONSOLE_USB_SERIAL_JTAG || ESP_CONSOLE_SECONDARY_USB_SERIAL_JTAG default y help When software switches the CPU clock source from BBPLL clock to XTAL, usually the BBPLL will be switched off. This helps to save some power consumption in sleep modes. However this may also happen during the software reset, resulting in the inactive (disconnected from host) of the USB_SERIAL_JTAG device during software reset. When USB_SERIAL_JTAG is being used, whether to turn off the clock source during software reset and in sleep modes is determined by RTC_CLOCK_BBPLL_POWER_ON_WITH_USB. - When RTC_CLOCK_BBPLL_POWER_ON_WITH_USB is enabled, the clock will be kept, so that the USB_SERIAL_JTAG will keep alive during software reset. The side-effect is the increasing of power consumption during sleep modes, even though USB_SERIAL_JTAG will not work in sleep modes. - When RTC_CLOCK_BBPLL_POWER_ON_WITH_USB is disabled, the clock will be turned off. USB_SERIAL_JTAG will be inactive during software reset and in sleep modes. This saves some power consumption in sleep modes. When USB_SERIAL_JTAG is not being used, software will always turn off BBPLL regardless of RTC_CLOCK_BBPLL_POWER_ON_WITH_USB is set or not. endmenu endmenu
