Murata 1ZM in Android

[esqui2002]

Hi, 

We have the Murata 1ZM Wifi and Bluetooth module and we are trying to work in Android Automotive 12. 

We have followed the guide to use 88w8987 based modules in imx8 but no results. 

What's more, after loading the driver we don't see any records related to the module in the log.

Does anyone have any idea how to make it work on Android or can give us a guide to follow?

Our board is imx8QXP mek with the baseboard. 

Thanks

Hello @esqui2002 

see schematic , please!  M.2 connector doesn't support SDIO signals on BB board. so this is the root cause.

Hi @esqui2002 ,

I checked I.MX8QXP design files,  there is no usdhc signals from CPU board to BB board.  because the BB board is shared with i.MX8QM-mek, and sd socket is for i.mx8qm, not for 8QXP CPU board.

so please use usdhc1 interface on CPU board !

Try it, please!

Hi @weidong_sun 

Thanks for your reply.

Our 1ZM module is the m2 version, so, we are using the m2 socket included in the I.MX8QXP, not the sdcard slot. 

We need to modify the dtb to enable m2 module?
