Can you expand a bit on what you're trying to do? Is the 1MByte flash separate from the flash containing your code? What are you trying to save, and why does it need to be on an external flash? If you only need to save some data, maybe the nvs subsystem in esp-idf can help you?

...Yes, I got that from your first post. Can you also try to see if you can answer the other questions I asked? If not, I'm afraid helping you is going to be pretty hard.
