Murata 1DX driver issue


Hello all,

We have a custom board with STM32MP157FAC1.
Kernel version is 5.10.153.

I know that Murata 1DX is used on STM32MP157C-DK2 board and that's why we choose it to use in our product.

But in our case, module is waiting in loading state.

The command for probe the module:


modprobe brcmfmac debug=0x1FFFFE


 The output:

From that point, we cannot event reboot the board properly. 

The important part is, we made it work with the kernel version 5.4.

Can anyone please help about this issue?

Also did anyone test Wi-Fi connectivity on STM32MP157C-DK2 board with kernel version 5.10.X?

The problem seems to be that it doesn't detect the platform. Could you check the /lib/firmware directory to make sure the 1DX firmware is present ?
