esp wroom 32 interface with external flash(winbond 1 mega byte)

[kamesh]

hi,

Can anyone worked on espwroom 32 interface with external flash (1 MB). I need to write and read the string on it by using SPI.

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?

hi,

I want to write and read data from flash. can you give suggestion on that.

[ESP_Sprite]

...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.
