Cannot bring up Murata wifi module on MYD-JX8MPQ having iMX8MPLUS chipset

[sanum19]

Im trying to interface murata(SDIW612) wifi module in n mydjx8mpq. The wifi interface is SDIO alone on the board.Kernel is 5.10.9...

I tried following the steps in nxp's bringup documents:

 |

 |

 \/

root@imx8mqevk:~# nano /lib/firmware/nxp/wifi_mod_para.conf
Content of the configuration file:

SDIW612 = {
cfg80211_wext=0xf
wfd_name=p2p
max_vir_bss=1
cal_data_cfg=none
drv_mode=7
fw_name=nxp/sduart_nw61x_v1.bin.se
}
• Load the modules in the kernel
root@imx8mqevk:~# modprobe moal mod_para=nxp/wifi_mod_para.conf

<>

Couldnt find sduart_nw61x_v1.bin.se - this particular file inside /lib/firmware/nxp. Where can i get it for kernel 5.10.9?

expected loglog fom my device

shaun_wu THanks for the reply.

Even after i tried adding these files. Couldnt laod wlan in my setup.

when i does - modprobe moal mod_para=nxp/wifi_mod_para.conf : The above SS is what  the expected log as per the documentation and dmesg log that, i get.

The kernel im using is 5.10.9. In the link you shared me the req file is found under branch 6.1.36 .Does that mean IW612 doesnt have support on kernel 5.10?

Hello @sanum19 

You could use 

ifconfig -a

 to check if mlan0 are enabled successfully.

mlan0 or wlan0 interfaces are not coming up on "ifconfig -a". Also the dmesg log shows no error. This is were i'm troubled with.

The module is inserted and are loaded in mmc0. Here is the log :
