How to Read & Write onto the External Flash integrated in nRF7002dk

[Obaid Mufiz]

I have an nRF7002dk & its datasheet mentions that there is a 64 Mb external flash memory. The memory is connected through a regular highspeed
Serial Peripheral Interface (SPI) .
The memory is connected to the chip using the following General-Purpose Input/Output (GPIO)s:
P0.11 CS
P0.08 SCLK
P0.09 MOSI
P0.10 MISO

I am trying to run a basic test using the spi_flash sample but looks like it only works with nRF5340 & other nRF5 series boards, nothing about the 7002 dk is mentioned.

What changes do I make in the boards files or create an overlay or conf file ?

You're looking at fairly beginner level developer here, so not much aware of the nrf stuff.

Hi,

You should wait for official reply from Nordic team but I have the same kit and looked at the documentation for the DK.

There it seems you need not change anything in the hardware to get the External chip working it is connected on SPI interface. You only need to do some modifications in case you want to change power domain and measure the current consumption by the Chip as well.

Thanks for the input.

That's exactly what my question is.

I need to know what changes I need to be making in the configuration files in order to test this out.
