Qspi NAND Driver

I've read quite a few threads where people are asking for help getting NAND Flash to work with their devices, only to find out they are not supported. I see that only NOR Flash is supported and it seems like that's not changing anytime soon. 

I wanted to ask if anyone has written their own driver to accomplish this? I am in need of adding the Winbond 25N into our company's design that uses the nrf52840 and was looking for a good starting point, as I'm am new to doing embedded work through an SDK. 

Thanks for any advice.

  • Hi Ron

    Can you give me some details on what you are planning to use the flash device for? 

    Do you have an estimate of how much and how often you have to write/read to the device?

    The main limitation of NAND devices is that they don't support random data access. For general data storage this is usually not a problem, but if you want to run code directly from external flash it is not ideal.
