Qspi NAND Driver

[RonT]

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.

We will be replacing our eMMC with this Nand memory. It is used to store logged data and config data, the data is transmitted at certain intervals over cellular for our backend online software. We also incorporate BLE, GPS, and Wifi in this device. This is a tracking/monitoring device we use at FedEx and it is used world wide. Currently tracking and monitoring all Covid vaccine shipments we deliver. 

We will not be running code from this memory. 

Thank you for your reply, too.

Hi 

Thanks for the added information. I will make some inquiries internally if we are planning to add NAND driver support, but I doubt we will be able to provide anything in the short term. If you need something immediately you might need to roll a driver of your own, or port a driver from another platform. 

Best regards
