iMX8QM MEK (imx-automotive-11) WiFi is not working with 1 YM M2 module.

[Jose1985]

Dear Team,

I connected a Murata 1YM M2 module for enabling Wifi and Bluetooth in iMX8QM MEK board.

https://www.embeddedartists.com/products/1ym-m-2-module/

However, when I am rebooting it seems that the WiFi module is not coming up.

The error log is as below.

Could you help me solve this issue? I think the pcie*.ko doesnt exists at

vendor/nxp-opensource/kernel_imx

Do you have a patch to make this work?

Best regards

Jose

Dear NXP Team,

I update the source to Android Automotive 11.0.0 2.3.0 and WiFi is working. However, there is a problem with Bluetooth. I shall report another issue

wlan: version = PCIE8997--16.92.10.p213.2-MM5X16266-GPL-(FP92)

Thanks and regards

Hi Team,

Kernel version seems to be 5.4
