nRF52840 : QSPI <--> USB MSC example

[tommy.park]

I want to save data to NAND Flash Memory (W25M02GV) and extract data to USB MSC. If you have an example of this, I want to get help. The SDK is using 15.2.0.
nRF52840 -> QSPI (W25M02GV) -> USB MSC -> Window explorer
Please ask for advice and help.

Importantly, the control of this chip is W25M02GV.

I would like help with the function of orange.

* QSPI(W25M02GV(2Gbit)) --> USB MSC --> window explorer

Thank you.

Hi,

Yes, we have a similar example in the SDK. You can read about it here.

Yeah! I know an example for that.
Thank you.
I would like to control the W25M02GV chip.
Also, I would like to know if NAND Flash works in SDK 15.2.0.

I don't think that it should be a problem as long as the flash supports the QSPI interface, but you would need to modify the code as some of it is written specific for the flash that is on the DK.

EDIT: This is not entirely correct. The example is written to support NOR flash with QSPI interface

Thank you.
I want to know how to fix it and how to control the W25M02GV chip.
Is there a successful case using NAND Flash in SDK15.2.0?
If you have a case, I would like to get some example help for that.

Hi,

I don't know for certain if it will work with the NAND FLASH since we don't use on the DK. Any necessary changes to the code has to be done by yourself as we don't support the W25M02GV. 

Best regards
