nRF7002 WIFI performance based on the nrf7002 PDK

[paul zhang]

Hi:

     We want to test the nrf7002 WIFI performance based on the nrf7002 PDK.Do we have relevant test firmware?

     We noticed that the sdk document of V2.1.2 has a description of the radio test,  but the SDK of V2.1.2 does not contain the source code of the radio_test example. this path contains only shell examples. Have you updated the sdk version to support this function. Or whether to update the hex firmware for us to test.

Hi Paul,

You can find the radio_test sample documentation and source code in the new NCS v.2.2.0, which released on GitHub a few hours ago. It will show up in the Toolchain Manager soon!

From what I can see, this sample wasn't present yet in v2.1.2.

Best regards,

Raoul

We encountered some problems when compiling and running.

This is compiling log,Does this mean the code is lost?

Did you test the example of shell or radio_test,I can't run these examples on nRF7002-PDK.

The 7002 build code is N7002QFAAAA.

The 5340 build code is N5340QKAAD02042AA

PCA10143 version is 0.2.1 2022.36

this is  uart log when we run shell example in the SDK V2.2.0:

Hi Paul,

It seems that your last two replies are related to the same issue, of the WiFi device driver not being found.

I am out of office and don't currently have access to nRF7002 hardware, so another colleague will take a look at your case and get back to you soon.

Thanks for your patience.

Best regards,

Raoul

Hi Raoul,

Is there any update on this issue?

This samples of shell has no problem when running in sdk v2.1.2, but it has this issue when running in sdk v2.2.0. I has this issue too.

Best regards,

Pany

Hi Pony and Paul!

So, the nRF7002-PDK has had a revision A and revision B release. It turns out that NCS v2.2.0 configures the firmware for revision B by default, and it is not backwards compatible with revision A.

To fix this issue, set the following Kconfig flag to configure the revision A firmware:

CONFIG_NRF700X_REV_A=y

That should do it.

Best regards,

Raoul
