nRF5340 NAND FLASH

[Hannibalhz]

Dear Nordic Engineer

  I currently have a project that requires 5340 to act as an MCU. I also need to plug in a FLASH, which is 4GBIT NAND FLASH. Is there an example of supporting NAND FLASH in NRF CONNECT SDK?

   Looking forward for your reply, thank you!

Hi,

 

Is there an example of supporting NAND FLASH in NRF CONNECT SDK?

 No, unfortunately not.

Hi Sigurd

    Thank you for your reply ! The hardware interface of NANA FLASH is QSPI. Can I use QSPI routines to write the NAND FLASH driver by myself?

 I think this will be difficult with the lack of NAND Flash protocol support in the QSPI peripheral.

Maybe find an external flash that uses regular SPI instead? or find a NOR Flash device if you need to use QSPI.

Hi Sigurd

    Thanks for your reply, I will try to use NOR FLASH for my project.
