nRF52840, QSPI, FATFS, NAND flash

[pact]

Hi,

We are using Micron NAND flash MT29F8G01ADBFD12 with QSPI.
We are referring qspi, usb_msd example in sdk 17.0\examples\peripheral\usbd_msc. Able to read device ID of NAND flash.
But when configured QSPI as block device in usb_msc example getting "mount failed" with FR_NO_FILESYSTEM error.

1.Does nrf52 sdk 17.0 supports QSPI for NAND flash.
2.If not, does custom instructions work with qspi nand flash.
3.Can we modify QSPI pins as SPI blockdevice and communicate with NAND flash.

Hi

1. I'm afraid our SDK does not support QSPI for NAND flash as some instructions are hard-coded for NOR flash.

2. Yes, custom instructions should work, but this will be up to you to implement.

3. I will have to come back to you on that, as I am not sure and need to ask the developers of the QSPI peripheral about this.

Best regards,

Simon

Thankyou for your response. Let us know as soon as possible, whether we can do with QSPI pins as SPI blockdevice .
