help
|
||||
If enabled, chip will try to power down flash as part of esp_light_sleep_start(), which costs
|
||||
more time when chip wakes up. 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.
|
||||
|
||||
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.
