RE: [nRF5340 + nRF7002] MbedTLS + WiFi BLE Provisioning

Hi Sagar,

Thanks for checking with us.Let me explain you questions one by one.

[quote user=""]my question is that can we successfully build and run the mentioned sample application for nrf7002dk_nrf5340_cpuapp_ns board or in general _ns board type ?[/quote]

It should work with most Wi-Fi samples when built with ns, but this option is not fully tested, and as you can see, it may not always work.

The SECURE FAULT likely means that code from the non-secure domain is attempting to access secure memory.

This is probably caused by memory restrictions since nrf7002dk/nrf5340/cpuapp already consumes a significant amount of resources, as noted in the Memory requirements for Bluetooth LE-based provisioning.

So, another question is can we build the project for secure board configuration (nrf7002dk_nrf5340_cpuapp) when MbedTLS is enabled ?

In short what i want to ask is that can these two functionalities work together or not ?

You can refer to the sample Cellular: nRF Cloud multi-service, it also support nRF7002DK. Here the combination of nrf7002dk/nrf5340/cpuapp/ns and MbedTLS are enabled, which are more commenly used due to all the crypto operations are run on the secure side of the device. nrf7002dk/nrf5340/cpuapp and MbedTLS may be possible but we do not have much reference to share.

Best regards,
Charlie
