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,

I am not sure with the configuration you are following because I haven't worked with this external flash and I can't test this here. But have you configured your Chip select pin properly in the overlay file?

Can you share the project? I will try to build it here. Please attach the Zip file using insert tab.

Kind Regards,

Abhijith
