Support External QSPI Flash

[ran]

Hi, 

We are planning to add an external flash to our nrf52840 based design. 

The flash type is

I'd like to know if anyone have used this memory before with 52840 ? 

I would appriciate if you can verify QSPI controller works well with this flash 

Thanks

Thank you, ran,

 I can't find any customers who have needed support for this before, but that does not mean that no one has used this device.

I would appriciate if you can verify QSPI controller works well with this flash 

 From the datasheet, this looks like it should work (NOR flash). I suggest comparing this to the flash used on the nRF52840 DK.

A simple test using the QSPI sample should give an indication if it works.

Kind regards,
Øyvind

should this one be ok ? Look like it is SPI compatible

Yes, this looks correct as well. 

NOR flash with QSPI. Looks similar to the MX25R6435F available on the nRF52840.
