ESP32 Forum

Hai,

I am not able to configure dedicated spi flash pins (gpio6 to gpio11) as general purpose I/O. Suggest how it can be done and explain the functions of the corresponding pins. I am using sdk v 2.0.


Thanks,

Might that be because your main SPI flash is connected to these pins, and your code is stored on that?

Yes I am flashing my code

In general, esp32 is always using flash pins to reload the cache so you cannot use flash pins as gpio. This is different to other mcus that load the whole program to ram from flash at startup.
