Hi Aidan,

[quote user="Aidan Eglin"]How does Zephyr WIFI Management know that 1/ we're using the nRF7002[/quote]

This is configured through Kconfig options. When you set CONFIG_WIFI_NRF70 to y in your project's configuration, you're telling the system to use the nRF Wi-Fi driver for the nRF70 Series devices. For Sysbuild projects, you would use SB_CONFIG_WIFI_NRF70 instead. See the nRF Wi-Fi driver.

[quote user="Aidan Eglin"]2/ what QPSI configurations we're using?[/quote]

For the nRF7002DK, the nRF5340 host processor communicates over the QSPI bus with the nRF7002. See https://github.com/nrfconnect/sdk-zephyr/blob/v3.7.99-ncs2/boards/nordic/nrf7002dk/nrf7002dk_nrf5340_cpuapp.dts#L26 and Driver to nRF70 Series device communication.

Hope the Wi-Fi Fundamentals would help.

Thanks Amanda, I appreciate the support. I have previously used the custom boards guide & have followed through the Fundamentals & Intermediate course. My question is primarily related specifically to the nrf7002 - for this chip in particular, I'm struggling to find clear hands-on documentation for common functionality in a way that's easy to transfer to a custom board. Do you have any particular tutorials that may be most useful in this case?

For example, let's take a look at this sample: https://github.com/nrfconnect/sdk-nrf/blob/main/samples/wifi/scan/src/main.c. Where can I read more about "how" this works? How does Zephyr WIFI Management know that 1/ we're using the nRF7002 and 2/ what QPSI configurations we're using? I'm probably just missing something in the docs somewhere but right now I feel like I've got a gap in my understanding of how this works, which makes me apprehensive to use it.

Cheers,

Aidan

Hi,

You can refer to this Developing with custom boards guide, which explains how to add your custom board to the nRF Connect SDK. For learning about device tree configuration, the Nordic Developer Academy offers courses that cover this topic: Lesson 3 – Adding custom board support

Here is the nRF7002DK board file: https://github.com/nrfconnect/sdk-zephyr/tree/main/boards/nordic/nrf7002dk , for your reference.

For a more structured approach to learning device tree customization, you can check these courses:
