ESP-WROOM-32 Serial Flash

Postby BrettG » Wed Feb 15, 2017 7:55 pm

Hi, I am trying to design a board with the ESP-WROOM-32. I want the ability to load base code and settings onto a serial flash chip and be able to Factory reset back to that code/settings. My confusion comes with the 4 MB serial flash (GD25Q32) within the ESP-WROOM-32 module. Can that serial flash be used for my purposes or does it perform other important function? Will I have to add another serial flash to the PCB to allow my desired functionality?

Also I would like to know if there is any already exiting code etc that does the factory reset that I described above.

Any clarification on this would be greatly helpful.

Thanks,
- BrettG

Yes refer to the factory partition: http://esp-idf.readthedocs.io/en/latest ... ables.html

You would have to write a small function that selects the factory partition and erases your user data to perform a factory reset.
