■ Question
Does imx-6.1.55-2.2.0 support the bluetooth and wi-fi function(driver/firmware) in IW611 module?

■background
bluetooth and wi-fi function didn't work.
I would like to check just to be sure because there is a possibility that it is not supported, as the article below.

Hi, @takeshi100 

Yes,  imx-6.1.55-2.2.0 support the bluetooth and wi-fi function(driver/firmware) in IW611 module.

Are you using IW611 uSD module?

If you are using our NXP own I.MX8MM-EVK and IW611 uSD module and connect it through SDIO, please make sure you have changed the default dtb to imx8mm-evk-usd-wifi.dtb. Because on our own I.MX8MM-EVK, there is another default 88W8987 module. If you do not change dtb, it will load 88W8987 driver and FW in default.

And also, if you are using our own I.MX8MM-EVK, you can download our prebuilt image through here:i.MX 8M Mini EVK It is more convenient than building by yourself.

Best regards,

Christine.

Thank you for replying!!

I have another question.

"Firmware Init Failed" is happend, what could be the cause?

Hi, @takeshi100 

Thanks for your feedback and shared us dmesg logs.

From your given logs, I see "cmd53 read error=-84" , this error usually related to SDIO communication.

I suspect the SDIO on your side doesn't work well.

And also if I am correct you are using our I.MX8MM-lpddr4-evk, so can you let me know you are using IW611-EVK or module? which partner's module? Can you let me know the module's name and model?

Are you using M.2 interface or Micro-SD(SDIO) interface?

Besides, please also provide me your full dmesg log so that I check what the SDIO card is detected to.

Best regards,

Christine.

> I use moudule. And, I don't use imx8mm evk board, use custom board. I develop in an imx8mm-evk based environment.

which partner's module? Can you let me know the module's name and model?

Are you using M.2 interface or Micro-SD(SDIO) interface?
> module have M.2 interface. but it convert to sdio interface and connect imx8mm.

[Christine_Li]

Hi, @takeshi100 

When you are using M.2, it converts to sdio interface to connect to 8MM.

So which usdhc interface are you using? usdhc1 or usdhc2?

Can you please provide me your dts file to check?

You can refer to our i.mx8mm-evk.usd-wifi.dts to modify your dts file.

Attach our imx8mm-evk-usd-wifi.dts file for your reference.

And also, please confirm the voltage for your module, it is 1.8v suggested.

Best regards,

Christine.

Hi, @takeshi100 

Any updates on this issue?

Anything else I can do for you?

Best regards,

Christine.

[takeshi100]

Thanks for a lot.

It seemed like the wiring on the custom board was bad.
For example, aerial wiring.

I plugged wifi/bt module directly into the SD slot on the imx8mm-evk board and it worked.

[Christine_Li]

Hi， @takeshi100 

Thanks for your feedback and your test.

Then I will close this case for now.

Please check the customer board, if need anything from our side, please feel free to create a new case to us. 

Have a nice day~

Best regards,

Christine.
