Dear Elena,

I'm glad to hear that it worked. I'm not sure why I didn't get a build error when trying to delete the 'nrf7002' node, but looking at the board file again it is the nrf700x node I should have deleted, same as you already did.

Dear Vidar,

Thank you very much for your patience and help. We have tried a little bit based on your idea and it works fine!

Here is the important part of the overlay-file:

Dear Elena,

I'm surprised you get an error when you try to delete the 'nrf7002' node as this node is defined in the original board file. Please try to build the attached sample and see if you get the same build errors. It built against SDK 2.4.0 without errors here.

devzone.nordicsemi.com/.../shell_5F00_spi.zip

Kind regards,

Vidar

Dear Elena,

The problem appears to be that your build does not include the 'spi_if.c' file located in /v2.4.0/nrf/drivers/wifi/nrf700x/zephyr/src/qspi/src. This file should be included automatically when you have the compatible 'nordic,nrf7002-spi' selected in your DT and not 'nordic,nrf7002-qspi'.

Please try with the overlay below and see if you get the same result. Main difference is that I deleted the 'nrf7002' first.

// To get started, press Ctrl+Space to bring up the completion menu and view the available nodes.

// You can also use the buttons in the sidebar to perform actions on nodes.
// Actions currently available include:

// * Enabling / disabling the node
// * Adding the bus to a bus
// * Removing the node
// * Connecting ADC channels
