The pins are still connected to the flash, and putting random levels on these pins may still affect what the flash does. I read on a Russian forum that for ESP8266 (in DIO mode) there is such a solution as to tell flash memory not to use WP, but to use a software WP. I.e. the memory will ignore the...

According to the C3's datasheet: For ESP32-C3FH4AZ, pins within the frame (namely pin 19 ∼ pin 24) are not bonded, and are labelled as ”not connected” These pins are the flash SPI and correspond to GPIO12-17. So no, GPIO12-17 cannot be used on the ESP32-C3FN4 because they are not electrically conne...

Hi For ECP32-C3 pins 12,13 are used as SPIHD and SPIWP (flash). However, in some descriptions of the boards on this chip, and in some other places, I find mention that pins 12,13 can be used as standard user GPIOs if switched to DIO mode. Does this correspond to the truth? I'm using Arduino, DIO mod...
