For legacy compatibility it will be very useful to have the equivalent of Esp8266 EEPROM.h library available.
Idf Nvs provide a very powerful tool to write and read data's from Flash memory but do not replace easily Arduino or Esp8266 code written for EEPROM .
Looking to EEPROM.cpp I have seen that , there , all flash related calls are a flash_spi_write and a flash_spi_read call that exist identical in Esp32 IDF. From my ignorant standpoint it should be possible ,having a flash sector address available for that , compile EEPROM library with no modification!
Is this feasible? Any flash sector that could be used without impacting/overlapping other flash utilization?
