Hi,

I do not know their plans regarding this, but I will register it as a feature request. I cannot comment on the schedule since this needs to be prioritized against other tasks.

Best regards,

Thank you for the answers Marte.
In Future, will there be an example showcasing this firmware update on nRF7002 in the zephyr project?

Regards,

Hi,

[quote user=""]Will these nRF7002 update patches be available in Zephyr driver releases in future?[/quote]

Firmware patches are hosted on sdk-nrfxlib and will need to be manually fetched using west blobs fetch hal_nordic.

[quote user=""]Is there any licensing aspect to note when storing the nRF7002 patch on RT500 MCU's memories?[/quote]

The firmware bins are licensed as Nordic-5-Clause, but they can be downloaded from non-Nordic hosts. For details, see https://github.com/zephyrproject-rtos/hal_nordic/blob/master/zephyr/module.yml and https://github.com/zephyrproject-rtos/hal_nordic/blob/master/zephyr/LICENSE.txt.

Best regards,

I assume it will be available in some form, but as per Binary Blobs, Zephyr does not allow hosting blobs within its repos. I will check this internally.

I will check this internally as well.

[quote user=""]Does nRF7002 need access to external memory for this feature as mentioned here? Or MCU connection to nRF7002 is enough for ensuring this?[/quote]

This is handled by the host MCU, so the nRF7002 does not need access to external memory.

[quote user=""]Are there any example patches available that I can try this on nRF7002 using nRF5340 to understand the flow?[/quote]

The default binary is located in nrfxlib/nrf_wifi/fw_bins/default/nrf70.bin, so you can try this.

I will get back to you when I hear from the team, either later today or early next week.

Best regards,
Marte
