[Bastelschlumpf]

This definition is part of the M5Paper library
In my case in the folder
c:\Users\xxx\Documents\Arduino\libraries\M5EPD\src\utility\BM8563.h
Either you have not yet installed the whole M5Stack library via the Board Manager or you have not yet selected the M5Paper board in your Arduino environment.
Tools/Boards/M5Stack Arduino/M5StackPaper

[IR4TE]

Everything is installed and the M5Paper is selected in the whole list of M5 Boards

[Bastelschlumpf]

The definition is in my case in the file
c:\Users[user]\Documents\Arduino\libraries\M5EPD\src\utility\BM8563.h
I used Arduino IDE 2.3.1 with the
M5Stack Arduino Library 1.0.7
No idea, what the problem could be.
Search the BM8563.h file and check if the "rtc_date_t" definition is in the file.

Same issue as well.
Compilation error: 'rtc_date_t' was not declared in this scope

[designdevy]

Ok I was able to fix it by deleting arduino ide completely and installing IDE 2.3.1 m5stack board and libraries from scratch.
