Hi,
I would like to allocate some variables in the ROM memory address of the Espressif, so I can acess to them, change it's value and keep its value constant between each turn off-on process.
I know I can do it with an EEPROM memory, but I would prefer not using this peripheral.
How do I allocate those variables?<br/>
I'm coding in C and using ESP-IDF Eclipse and CMAKE to build the project.<br/>
Thanks,
Pablo

Re: ESP32 fixed variables in ROM
The ROM in ESP chips is Mask ROM not EEPROM. So it is literally Read Only Memory.

Re: ESP32 fixed variables in ROM
As an alternative, nvs probably approximates what you want (although you still need to save your values manually)
