I have some important data that is periodically updated and I want to store it, but I don't want to store them directly on the flash, because this will affect the service life of the flash.
Therefore, I would like to know if esp32 has such a storage area, when the program restarts or crashes, the data is not lost until the device is powered off.
Is there an area in esp32 where data is not lost until the device is powered off？

You should be able to use the RTC_NOINIT_ATTR on a variable to achieve this.
