I'm using new ESP32-S2 for my next design. My main MCU will be communicating with ESP32-S2 via UART using AT Commands. In the hardware design guidelines, it is written that the SPI Flash is Compulsory (PFA). So my question is, since I will be communicating using AT commands and will not be loading c...
