RT-1050 lpspi with SLC NAND Flash Driver

greg_nowak — Wed, 11 Mar 2020 20:28:23 GMT

Does the RT-1050 support an Serial SLC NAND flash chip on the lpsi interface?

If so, are there any libraries out there provided by NXP?

The reference manual seems to reference NAND Flash in the SEMC section, but not in the lspi section. The NAND flash example drivers all seem to point to SEMC based SDRAM type applications, not just external storage in NAND flash that doesn't use the SEMC interface.

I'm using a Winbond 1 G-bit external NAND flash for data storage. Currently it is hooked up to my lpspi pins on the RT-1050 since I have SDRAM on the SEMC pins and program flash on the QSPI interface.

I'm not very familiar with the RT-1050 so I might be over complicating it and getting lost in the plethora of examples provided.

Note: I'm not looking to "boot" from this chip, I'm just looking to read/write to it to store temporary files.

The specific flash chip is this: W25N01GVZEIG TR

Hi,

Unfortunately, we don't have related lpspi driver for W25N01GVZEIG.

Have a great day,
Mike

Mike,

If I were to move the W25N01GVZEIG to the QSPI interface, is there a QSPI driver for interacting with NAND flash devices?

Hi Greg,

Yes, please check MCUXpresso SDK for RT1050 mcu-boot folder with below path:

\SDK_2.7.0_EVKB-IMXRT1050\middleware\mcu-boot\src\drivers\flexspi_nand

I also attached a [Flexspi access serial NAND Flash] demo for your reference.

Wish it helps.

best regards,

Mike
