Resolving WLAN Initialization Error When Connecting Maya-W2 (IW612) SDIO to RT1060-EVKB

[pooisonner]

Hello,

I have built and ported the Matter thermostat example on the RT1060-EVKB board.
The project was built for RT1060 + IW416, and I attempted to connect the Maya-W2 (IW612) to the EVK board by inserting the SDIO of the Maya-W2 EVK into the SD card slot of the 1060 board. However, the following error occurred:

```
[0] [INFO] [DL] Welcome to NXP thermostat Demo App
[5] [INFO] [DL] Sunny Build
[13] [INFO] [DL] Initialize WLAN
[wifi_io] Error: SDIO - FW Ready Registers not set
[wifi] Error: sd_wifi_init failed. status code -1
[wlcm] Error: wifi_init failed. status code -1
[10025] [ERR] [DL] WLAN initialization failed

```

Could you please explain how to properly connect them?
Thank you.

Hello,

Hope you are doing well. Is there a particular reason why you are using the RT1060-EVKB with the IW612?

Could you please share the Matter version you are working with and images of your board setup?

There is also a rework needed for the EVKB to select whether to use the uSD or the M2 interface since they cannot be working in parallel. You can find this information in the following paths: (…\<path-to-SDK>\docs\wireless\Release Notes) and (…\<path-to-SDK>\docs\wireless\Bluetooth), could you confirm that you have this rework done?

Best Regards,

Ricardo

Hello, sorry for the late reply.

I am working on the Matter project and reviewing the optimal solution, and for developing a thermostat, the rt1060 was suggested in the example, so I proceeded with that solution.

I am currently using VSCode as my development environment.

I couldn’t find the path you mentioned, so could you please check it again?

Here is a photo of my board.

Hello,

In the Matter project for NXP platforms guide, it is recommended to use the MIMXRT1060-EVKC since, as mentioned in the IW611/IW612 release notes, the support for these modules is enabled only in MIMXRT1170-EVKB and MIMXRT1060-EVKC.

The path that I mentioned is by downloading the SDK v2.16.100 form the MCUXpresso SDK Builder platform, however you can access the same documentation about the boards in MCUXpresso SDK Documentation.

Regards,

Ricardo

Thank you for your prompt response.
However, I am currently working on the Matter project in the VSCode development environment.
Could you please check if it is possible to develop the Matter project in the MCUXpresso IDE?
Thank you.

Hello,

No, for Matter you should use VSCode or a Linux environment.

I would recommend checking this community post: Getting Started with MCUXpresso for VS Code: Matter on Windows (24.12.71) - NXP Community
