Great! Glad you got it solved, and thanks for updating the forum with your solution in case anyone runs into this in the future 🙂 Let us know if there is anything else!

Hi Elfving,

Thanks for your time! I’ve configured the CPU clock to 520 MHz and set the SPI to 16 MHz. But that wasn’t the issue. I didn’t use NCS(2.9.1) because it’s still based on Zephyr 3.0.0(not sure), and the NXP drivers aren’t up to date there. So I switched to Zephyr 4.1.0, and now everything’s working fine.

You can go ahead and close the ticket.

Sorry about the wait Gokul,

The bustest logs show SPI freq as 9MHz while the system logs show 8MHz. Could you confirm what is being used?

And can you set the host HOST CPU freq to 128MHz and try the bustest again and share the logs?

Note that we would recommend using native Zephyr for this, our Wi-Fi support is upstreamed to enable this usecase.

Regards,

Elfving

Any updates??

Hi Håkon,
I actually already tried that. If CONFIG_WIFI_NRF70 is not enabled (which it isn't enabled /tests/boards/nrf/nrf70/bustest), it just skips the rpu_validate_comms() function.
I also tested the system bus and peripheral bus, but those tests failed as well.

Wops. My mistake.

You can find the test in zephyr/tests/boards/nrf/nrf70/bustest. Build it the way you normally would for your board.

Hi Hakon, thanks for your time! I'm unable to access the link.

 "mail_id" doesn't have access to Confluence on nordicsemi.atlassian.net.

Hi,

Can you try this bustest, to rule out faulty interfacing between the host and nRF70?

Håkon
