Hi MHT2020,

It looks like the ESP32 is having some problem talking to the attached flash chip. Can you give some details about exactly which ESP32 hardware (chip, module, etc) you used, or even a schematic (or piece of a schematic) to show how it's wired up?

Is anything connected to the GPIOs which are shared with the ESP32's flash chip?
