Is this bug been fixed? Or should we still be using another dummy RTC_DATA_ATTR variable just to keep the memory powered up?

Yes, has been fixed in https://github.com/espressif/esp-idf/co ... 158dbf6b4b for master and release/v3.2, and in https://github.com/espressif/esp-idf/co ... 7143985edc for release/v3.1.

Hi,


RTC_NOINIT_ATTR int waitFlag = 0;

Serial.println((String)waitFlag);

Why do I get this?

...because you tell the compiler not to initialize the variable, and that seemingly takes precedence over the fact that you tell it to initialize the variable.
