The expert confirmed my suspicion. This device uses a completely different interface, and will not work...

Thanks for the link, I was able to download the datasheet.

Having a quick look at the specification I got the impression the device is using an 8-bit parallel interface that will not be compatible with the 4-bit QSPI that we support. Unless there is an alternative mode that I didn't find?

I will show the specification to the experts and see if they have some input.

Best regards

Hi, The NAND device is am currently using is the MT29F4G01 4Gb from Micron, datasheet can be obtained from www.micron.com/.../mt29f4g01adagdwb-it, althought I think registration might be required to get it.

I would use a NOR device, however they have a limited capacity. I haven't found one that is > 1Gb and I need 4Gb at least. Due to size and cost constraints I also can't just get multiple of them.

Rgs, Bryan

Hi guys

I need some more time to dig into this, so far I haven't been able to find any NAND devices that we support.

Are you able to share the datasheets of the NAND devices in question?

Best regards

Hi there, I am also looking into using a QSPI NAND Flash as user data with a NRF52840 so this thread is also super relevant to me!

Cheers, Mickael

Sorry for the late reply. Most of the organization is away between Christmas and new years, and I will have to get back to you first week of January.

Best regards
