Environment: ESP32, uPyCraft, MicroPython

Hello,
Has anyone been successful in writing to the RTC user memory area using MircoPython?
There is help using C but not with MircoPython.
The RTC_DATA_ATTR attribute is used with C but is not available with MircoPython.
MircoPython has a “from machine import RTC” where it appears memory can be written but I
do not know the ESP32 memory map.

Thanks,
Scott
