Closing this case, we'll continue in the private ticket.

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

Hi again

Can you confirm/deny that this is the datasheet of the Flash device you're using? From what I can see here, this device does not have a QSPI or an SPI interface at all, and in that case, it will not be able to function as a SPI block device.

Best regards,

Simon

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

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
