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

The link you posted leads to the same NAND flash I linked to the datasheet of, which shows no mention of SPI/QSPI. We need to know which kind of NAND device (with SPI/QSPI) and see its datasheet to find out whether using it as a block device or similar will be possible. Please link to the datasheet of the NAND flash you're using, as there seems to be no mention of SPI in the datasheets I have found.

Best regards,

Simon
