Hi

I need more information on what exactly you're having trouble with, how are you writing and reading data from the Winbond device exactly? Are you seeing any error/return codes that could give us an idea as to what is going on in your application? Also there are multiple SPI examples in the nRF5 SDK. Which one is your application based on exactly?

• SPI Master example
• nrfx SPI Master example
• SPI Transaction Manager example

Best regards,

Simon

Please create a new ticket where you describe your issue in detail, as this is an old case at this point and it might not even be you're using the same SDK for development.
