Support for nRF7002 EK with nRF54L15 (SPI interface) - workspace configuration and missing driver issue

[Maulik Sojitra]

Content:
I’m working on integrating the nRF7002 EK over SPI with an nRF54L15 using nRF Connect SDK v3.1.1.
While setting up the workspace, I noticed that the Wi-Fi driver path nrf/drivers/wifi/nrf700x/ and the header nrf/include/net/wifi_nrf700x.h are missing in this version. Additionally, Kconfig options like CONFIG_NRF700X_ON_SPI and CONFIG_WIFI_NRF700X show as not directly user-configurable during build.

Could you please confirm:

1. Whether SPI connectivity between nRF54L15 and nRF7002 officially supported in NCS v3.1.1?

2. If so, which workspace, overlay, or configuration files should be used to enable Wi-Fi with this setup?

3. If driver sources were moved or deprecated, where can I find the correct references for this configuration?

Many Thanks :)

Hi,

Please contact your regional sales manager to obtain an nRF7002 EBII with an interposer board made for nRF54-devices, which makes it much easier to physically connect the two devices. See the Developing with nRF7002-EB II documentation. 

The nRF70 Series driver namespace has been renamed from NRF700X to NRF70. See Migration guide for nRF Connect SDK v2.8.0/ nRF70 Series

In v3.1.1, nRF Wi-Fi driver: 

• When using Sysbuild (System build) to build your application, set the SB_CONFIG_WIFI_NRF70 Kconfig option to y in your sysbuild.conf file.`

• When not using Sysbuild (System build), set the CONFIG_WIFI_NRF70 Kconfig option to y in your application’s prj.conf file.

CONFIG_NRF700X_ON_SPI is enabled by the devicetree. See https://github.com/nrfconnect/sdk-zephyr/blob/ncs-v3.1.1/modules/nrf_wifi/bus/Kconfig#L28-L32 

You can take a look at Wi-Fi samples and refer to the sample.yaml file under the sample to build for nRF54L15, such as this example.
