Unable to get the wifi working on IMX8M-EVKB using Android OS

[thomas_anderson_]

Hello,

I was trying to get my IMX8M-EVK board up and running by flashing the

android OS (version : Android 12.1.0_1.0.0 (L5.15.52_2.1.0 BSP)).

The issue I am currently facing is that I am not able to turn on the wifi network after the board boots up. In the UI when I toggle the wifi button to on, the UI freezes for a while and then crashes, and resets to default home screen.

Has anyone else faced this issue? how do I fix this?

I have attached a log file along.

Any help is appreciated.

Thank you.

Hi @thomas_anderson_ ,

I tried this using iMX8M Plus using a prebuilt image
Android 12.0.0_2.0.0 (L5.15.32_2.0.0 BSP) is working fine, I can set up a wifi network and use the internet.

Could you try this version on your own board?

Also, I will attach Android Quick Start Guide to help with the correct operation.

Best regards, Brian.

Hello Brian,

I think I should have provided you with some more information about my connections, hope this gives you more context about my hardware setup, and what I'm trying to do.

I have connected a MIPI display based on RM67199, on the MIPI DSI port of the board, and while flashing the android os, I have also flashed the "dtbo-imx8mq-mipi-panel.img" along with it, the command I used for the flashing process is:

sudo ./uuu_imx_android_flash.sh -f imx8mq -a -e -u trusty-dual -d mipi-panel

The issue I am facing with this setup is with the WiFi, I am unable to scan for any APs and the android UI freezes for a few seconds then crashes and resets to the home screen, as I have already mentioned in my original post.

I hope this extra information helps you in assisting my case.

The other thing I have tried is to bring up the board with HDMI output, in this case I have flashed the android OS with the default options using the command:

sudo ./uuu_imx_android_flash.sh -f imx8mq -a -e -u trusty-dual

But even in this case with the HDMI as output, the WiFi still fails to scan for any APs and is unresponsive, but in this case the android UI does not crash as it does with the MIPI DSI output.

I hope this helped you understand my setup, and what I've been trying to do.

Regards,

thomas.

Hi @thomas_anderson_,

Thank you for the extra information.
It seems the problem is related to a Wi-Fi Driver.
To continue with the case, could you please share your iMX8M EVKB version?
With this information, we can know the Wi-Fi module included in your EVKB and support this module specifically with the correct driver.

Also, you can review in the Android OS > Build Sources and Documentation > NXP Wi-Fi Driver Feature and Release Notes. To get more information about Wi-Fi module drivers.

Finally, thank you again and I look forward to your answer.

Best regards, Brian.

Hi Brian,
The iMX8M EVKB version is "700-38820 REV A", in the mean time I will gather info about the Wi-Fi module drivers as you mentioned.
Regards,
Thomas

Hi @thomas_anderson_ ,

Thank you for your reply.

Based on your iMX8M EVKB version "700-38820 REV A" the WiFi module is LBEH5UL1CX and is manufactured by Murata with chipset CYW4356 from Infineon.
Please contact Murata to update this module drivers in Android.

I hope this information will be helpful.
Have a great day.

Hi Brian,

Thank you for your response,

I tried the Android 12.0.0_2.0.0 (L5.15.32_2.0.0 BSP) version as you suggested.

But the same issue still persists, the UI keeps crashing as it did before and I am not able to see any scan results.

Regards, Thomas.
