ESP32 Forum

Hi, I'd like to know if its possible to use the flash API to connect an external flash(not shared with main flash) in dual mode and not use WP and HOLD, I have left only 4 pins and I don't wanna use an SD card beacuse of the vibration environment.

thanks

This should be possible, you can connect unused pins (WP and HD) according to the datasheet of the flash chip.

To see how to set this up in ESP-IDF, please check this example: https://github.com/espressif/esp-idf/tr ... lash_fatfs
