External flash memory

[PeWosT]

Hi, I have some nor flash memory like micron M25P80-VMW6TG, how can I connect them to my esp32?

Hi PeWosT,
You can look up the ESP32 datasheet. We use HSPI to connect external flash. You need to follow the protocol of HSPI.

Thanks

Dear Sir,

I am interested in using ESP-WROOM-32D. I would like to connect an external SPI Flash.

I have made some research on various forums related to above mentioned topic. I have learnt the following alternatives:

1. Connecting to HSPI interface (as mentioned in this post)

2. Connecting to the same SPI Lines as the internal flash, but using a different gpio as a chip select line and using efuse.

I would like to know if there is any configuration steps required to connect external HSPI Flash, do we need to use efuse.

It would be helpful if espressif can release a step by step guide related to interfacing external flash.

Does Espressif provide higher capacity flash in ESP-WROOM -32D modules

Thanks in advance

#2 is if you want to replace internal flash and boot from external flash. #1 is if you want to keep internal flash and add external flash for data. No efuse settings required for using hspi.

Thank you for the reply.
