how to connnect external flash(w25qxx) to nrf52833dk board and validate that it the spi communication has been enabled

[ALIKHAN]

hi i'm new to developing nrf applications i have practised the sampled examples from https://academy.nordicsemi.com/courses/nrf-connect-sdk-fundamentals/ but i'm unable to connect using the spi interface. I am currently using nrf connect sdk v2.2.0. It would be really helpful if you can help me establish spi communication with my external flash.

Hello,

While looking at your project file, I guess you have configured the device improperly in the overlay file. You haven't mentioned the SPI pins in the overlay and have only declared the CS pin there.

Please refer to this sample in the SDK there you can see how you can configure the overlay file properly.

You can find the overlay file under: C:\ncs\v2.2.0\nrf\samples\bluetooth\central_nfc_pairing

Kind Regards,

Hi Alikhan

i'm struggling with the same issue as you. Could you share your overlay that worked for W25q32 ?

Thanks
