The wifi driver will work like any other network driver that you have for the compute module. Have you tried compiling the fmac driver and insmoded it into the system.

Could you attach a error log if you are facing any issue while insmoding the fmac driver for the kernel that you are using?

I tried like that for raspberrypi by using this kernel

https://www.raspberrypi.org/documentation/linux/kernel/building.md

but its telling kernel is not configured with backports. I tried configuring kernel with backports but its not successful.

which version of backports to use with this kernel?

will Murata 1mw module directly work with raspbian?

Hi,

What is the kernel version that you are using ? <uname -a>

what is the specific error that you are getting.

Do you have an IO board for the compute module? Is the firmware for 1mw present in /lib/frimware/brcm/.

Hi ,

Kernel version i am using is 4.19.66-v7+

in /lib/firmware/brcm/ ,i found

brcmfmac43455-sdio.bin

brcmfmac43455-sdio.clm_blob

brcmfmac43455-sdio.txt

I have IO board for compute module,when i started compiling module for 1mw module by using backports ,raspbian kernel is not configured with backports,later i found that in forums they are using module directly.

So does 1mw module directly works with computemodule in raspbian?

I am also creating yocto image ,even in that kernel backports is not there.How to compile for that?

Hi, we are getting this error.

SDIO frequency set at 50MH

Do we have to configure pins on uSD-M2 module?
we pulled up WL_REG_ON pin with 1k resistor
