Ok Thank you.

In this sample, before main application, it initialise all the kernal config in z_sys_init_run function, It is working in DK board because all configuration satisfy but In our custom board we don't have SPI - external flash(mx25r6435f) connection, so it is stuck in configuring SPI. Hence we Disable mx25r6435f device. After that ble provisioning is working fine in our custom board.

Hi,

mx25r6435f is external flash but since you do not have external flash your device never gets ready, and you get devicetree errors.

Regarding your issue with provisioning, can you verify that you used correct COM port/ttyACM device? In addition, can you provide build command which you used? Please note that according to requirements, on the nrf7002-dk sample should be built for nrf7002_nrf5340_cpuapp (no _ns) build target.

These all working fine.

Please check into this.
Why the pointer not exit from z_sys_init_run? Are we missing any configuration?
Is Ble provisioning using external flash for storing WiFi credentials?

Furthermore debugging, it stuck into spi_nor_wait_untill_ready function. Please see the attached image for more details.

Hence we check the zephyr/spi_flash sample (nrf5340DK configuration). Got below output

While build with nrf7002dk-nrf5340dk facing issue

Are we missing SPI/Flash related configuration?Please provide your suggestion on this.

FYI, In our board we don't have external flash.

Hi Lavanya_Manohar ,

Did you make any progress regarding the reported issue?

Your problem does not seem to happen due to shared antenna.

Hi dario

1. If posible, Please chcek your board host + nrf7002ek. (isolate custom board nrf7002).

2. And check above(nrf7002dk schmatics) showing IC session in your board.(A1 and A2).

RE: Wifi initialisation fails nrf7002-nrf5340

dario.sortino — Mon, 08 Jul 2024 08:21:57 GMT

The whole custom board is powered at 3.3V

- Buck en fails to go to VDD

- I can' access directly IOVDD EN, but I can access the VDDIO pin of nRF7002 and it stays weirldy at 1.1V (IOVDD EN and VDDIO are related by the same Load Switch of the nRF7002DK)

In the dts:

&qspi {
    status = "okay";
    pinctrl-0 = <&qspi_default>;
    nrf700x: nrf7002@1 {
        status = "okay";
        compatible = "nordic,nrf700x-qspi";
        reg = <1>;

Hi dario,

1.Please check voltage in below points.
1. Buck En
2. Host IRQ
3. IOVDD En

2.Then check the QSPI configuration and pin for above mentioned in dts file.

Can you please explain the issue little bit more?

Hi dejans,

In our custom board, we don't have external flash. We suspect this could be the reason for the provisioning issue.

[quote userid="132929" url="~/f/nordic-q-a/112171/wifi-initialisation-fails-nrf7002-nrf5340/491963"]Now we can able to get terminal log. In that wifi error ocurring but ble is able to pair with mobile. here i share log[/quote]

After resolving the Wi-Fi issue, we noticed that we can no longer retrieve terminal logs for the provisioning code.

During debugging, we found that the pointer does not exit from the z_sys_init_run_level(INIT_LEVEL_POST_KERNEL) function, which prevents it from entering our main application. Consequently, no debug logs appear in the terminal. Please see the attached image for more details.

Since we are not using external flash, is there any specific configuration we need for internal flash to address this issue?

RE: Wifi initialisation fails nrf7002-nrf5340

dario.sortino — Fri, 05 Jul 2024 14:34:43 GMT

I am experiencing the same problem in my custom board. By any chance, can you share what are the changes you made in the custom board?

RE: Wifi initialisation fails nrf7002-nrf5340

dejans — Thu, 04 Jul 2024 09:15:15 GMT

Hi,

The first line in provided log shows Jedec ID mismatch. This could happen for a number of reasons ranging from configuration to hardware. You could start checking by using jedec SPI-NOR flash sample to test your external flash. If this works fine, you could compare the contents of .config and zephyr.dts files of your custom board with the ones provided for nrf7002-dk. For other possible causes, you could look at this jedec-id discussion.

Best regards,
Dejan

on our custom board, which has a single antenna shared between both BLE and Wi-Fi. We suspect that this might be the root cause of the problem, as the sample code utilizes both BLE and Wi-Fi simultaneously.

Could you please confirm if the shared antenna setup is indeed causing the provisioning issue? If so, are there any specific configurations or settings that we need to adjust to ensure proper functionality?

Now we can able to get terminal log. In that wifi error ocurring but ble is able to pair with mobile. here i share log

After some changes in our custom board, we are now able to initialize WiFi, and it works fine. However, we are facing the following issues:

1. WiFi Provisioning Not Working: The sample provisioning code is not working.Not even seeing the log.

2. MAC Address Not Programmed in OTP: In all our WiFi modules, we are encountering the "MAC addr not programmed in OTP" issue. For testing purposes, we use the CONFIG_WIFI_FIXED_MAC_ADDRESS="22:22:22:44:44:44" configuration. However, we need to use the actual MAC addresses of the modules for production.
It is essential for all modules to have unique MAC addresses. How can we include the MAC address into the module?
Do we want to create builds by config mac addr locally for all wifi modules individually?

It would be helpful if the modules had the MAC addresses programmed into their OTP instead of using a fixed MAC address configuration.

Hi,

Looking at your 4 questions asked previously, it seems that your problem might be hardware related. I suggest that you open a new private ticket where you would provide your schematic and PCB layout files and ask for a hardware review. After this is done and it is verified that the hardware is functional, you can return here with additional questions if you still have them.

RE: Wifi initialisation fails nrf7002-nrf5340

Lavanya_Manohar — Mon, 24 Jun 2024 09:54:29 GMT

Hi,

I will check on that. However, these transitioning steps are performed on the Wi-Fi code before initialization, which takes place in the sample code itself and is also needed for the DK.

So, how could it be different from our custom board?

RE: Wifi initialisation fails nrf7002-nrf5340

dejans — Mon, 24 Jun 2024 08:59:44 GMT

Hi,

You could look at the power state operation in the nrf7002 product specification which shows transitioning steps to Active state.

Yes, Dejan. We also suspect this point. so we tested voltage at pin wise (QSPI, BUCK en and power points).

As you mentioned that 2 points have no voltage. here I share the measured voltage at corresponding points. please check the table.

we are looking for suggestions on how to properly power up the nrf7002 module. We are currently using a sample project with the pin configuration identical to the Development Kit (DK).

Is there any specific pin configuration or additional settings that we might be missing to properly power up the nrf7002?
Are there any specific sequences or initialization steps required in the firmware to ensure proper power-up of the nrf7002?
Are there any external components or connections, such as capacitors or voltage regulators, that we need to double-check or verify?
Could you suggest any diagnostic steps or tools we can use to further isolate the issue and confirm if it’s indeed a power-up problem?
