Can only be enabled if there is no SPIRAM configured. This option will in fact consider VDD_SDIO auto power value (ESP_PD_OPTION_AUTO) as OFF. Also, it is possible to force a power domain to stay ON during light sleep by using esp_sleep_pd_config() function. 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 select PM_SLP_DISABLE_GPIO if FREERTOS_USE_TICKLESS_IDLE help esp32c3 and esp32s3 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 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" 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. 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 the chip goes sleep or software reset, the clock source would change to XTAL and switch off the BBPLL clock for saving power. However, this might make the USB_SERIAL_JTAG down which depends on BBPLL as its unique clock source. Therefore, this is used for keeping bbpll clock always on when USB_SERIAL_JTAG PORT is using. If you want to use USB_SERIAL_JTAG under sw_reset case or sleep-wakeup case, you shoule select this option. But be aware that this might increase the power consumption. endmenu endmenu
