Inquiry on STM32H747 + nRF7002 Wi-Fi Development with Zephyr

[Joey Wang]

Hi Nordic team,

We are planning to use the STM32H747 as the host MCU to control the nRF7002 for Wi-Fi functionality. Based on reference materials and existing use cases, it seems that the STM32H747 should be developed using the Zephyr RTOS and communicate with the nRF7002 via its provided APIs.

However, we are uncertain about how to get started. Should we use the Zephyr extension in VS Code, and download specific drivers or SDKs for STM32 and nRF7002 integration?

Could you kindly provide us with more detailed information on the recommended development setup (including IDE, SDK, configuration steps), as well as any application examples or reference designs?

Best regards,
Joey

Hi Amanda,

I’ve been following this GitHub thread:GitHub - chshzh/nrf7002ek-diff-hosts: Run Zephyr Wi-Fi samples using nRF7002EK with STM32/NXP chips as host. 
to set up the nRF7002 driver in the Zephyr SDK.

Currently, we’re trying to switch from SPI mode to QSPI (with DMA), but it seems we’re running into some configuration issues.

Could you help review or provide guidance?

Regards,

Try to enable CONFIG_NRF70_BUSLIB for the error. You can run this https://github.com/nrfconnect/sdk-zephyr/tree/ncs-v3.1.1/tests/boards/nrf/nrf70/bustest for the bust test.

nRF7002 is connected via QSPI with nRF5340 on nRF7002DK. You can take a look at this example https://github.com/nrfconnect/sdk-zephyr/blob/main/boards/nordic/nrf7002dk/nrf7002dk_nrf5340_cpuapp.dts
