nRF52840: How to set If use Nand Flash GD5F4GQ4RB to make USB MSC?

[WenLiYong]

Hello, All:

             Now I'm making a project that it should save mass data to NAND FLASH GD5F4GQ4RB by FATFS, then extract data to Windows by USB MSC.

I use the SDK 15.2.0 examples\peripheral\usbd_msc to develop,   The Nand flash of example  is W25Q64M,  and I have tested W25Q128M and it works normal too.

But it's fail if changing GD5F4GQ4RB chip.   I have test the  communication by QSPI, It can write and read data well.

            Please advise how to set in \usdb_msc\ directory? and Let Nand Flash GD5F4GQ4RB work normal. Thank You!

Hello, may I have a copy of your w25q128m routine? I'm in usbd_ MSc routine debugging, always can not identify the storage device on the windows computer. Thank you very much
