WIFI driver issue IOCTL issue

masateesh

Hi Team,

I am facing an issue wifi driver using marvell driver. driver -> marvell,sd8978

sdiouartiw416_combo_v0.bin wifi_mod_para.conf

root@ST-CUSTOMBOARD :/lib/firmware/nxp# cat wifi_mod_para.conf
SDIW416 = {
cfg80211_wext=0xf
max_vir_bss=1
cal_data_cfg=none
ps_mode=1
auto_ds=1
host_mlme=1
fw_name=nxp/sdiouartiw416_combo_v0.bin
}

kernel version - 5.15.67

Below I have attached full dmeg log.

[ 103.844811] CMD_RESP: cmd 0x6b error, result=0x1

sub_id -> changing 0x10003 & 0x1000b

status code -> 0x3 , 0x80000007

I am loading this wifi module using systemd service during bootup time.

ExecStart=sudo modprobe moal mod_para=nxp/wifi_mod_para.conf

Hello Christine,

I have created systemd servcie. As I mentioned below. once I login I have observed this issue. Previosly I have attached dmesg log

[Unit]
Description="Start WIFI"

[Service]
ExecStart=sudo modprobe moal mod_para=nxp/wifi_mod_para.conf

[Install]
WantedBy=multi-user.target

In my yocto environment I have created linux-firmware directory.

SDIW416 = {
cfg80211_wext=0xf
max_vir_bss=1
cal_data_cfg=none
ps_mode=1
auto_ds=1
host_mlme=1
fw_name=nxp/sdiouartiw416_combo_v0.bin
}

Additionally I not modified.

Hi， @masateesh

Thanks for your reply.

But your previous dmesg log is cut off.

It only has 418 lines, and after below line, there is no anything.

=======

[ 77.670774] wlan: mlan0 START SCAN
[ 82.814630] wlan: SCAN COMPLETED: scanned AP count=24

=========

Please help to check again and share me your full dmesg logs.

Best regards,

Christine.

Hi Christine,

I have attached complete log could you please check it.

Hi, @masateesh

Thanks for your reply.

From your given logs, I think you have loaded Wi-Fi driver and FW successfully and also Wi-Fi has been working properly.

I think the ioctl failed logs doesn't influence Wi-Fi function. It can scan and can connect with AP successfully.

But you can have a try with below commands to see whether can avoid these ioctl failed prints:

=========

root@imx8mnevk:~# systemctl stop connman.service //To stop this service

After stop connman.service, please do not use connmanctl to connect AP.

Please do not hesitate to reply me if have any other concerns.

Best regards,

Hi Christine,

I see wifi is working.

But below issue's I have observed. I am guessing moal driver some patch may required. I see same issue in this forum IOCTL failed somebody mentioned he have corrected DRAM configuration then issue fixed mentioned. I just want to know the clear on this.

Is their any patch is required please provide I will add those changes locally and built mlan, moal kernel modules.

Hi, @masateesh

Thanks for your reply.

From the given logs, I think IW416 is working as a STA and has been connected successfully with your AP.

I don't think there is issue during connection.

And can you please let me know whether my previous comment mentioned that disable connman service is helpful or not?

Besides, you can also update to our latest driver + FW combinations to see whether is helpful. I believe there must some fixes in our latest release.

Your current

wlan: version = SDIW416---16.92.21.p55.3-MM5X16366.p5-GPL-(FP92)

driver version:MM5X16366.p5

FW version:16.92.21.p55.3

Our latest

driver version: MM6X16437.P3

FW version: 16.92.21.p119.2

Best regards,

Christine.

Hi Christine,

Actually I am using wpa_supplicant & iw , I am not using connman.

Can you share me latest binary available link.

Regards,

Sateesh

Christine_Li

Hi, @masateesh

Thanks for your reply.

Connman service might be started automatically in Linux OS.

Our latest open source

driver link:

https://github.com/nxp-imx/mwifiex/tree/lf-6.6.3_1.0.0

FW link:

https://github.com/nxp-imx/imx-firmware/tree/lf-6.6.3_1.0.0/nxp/FwImage_IW416_SD

Please let me know if you have another queries.

Best regards,

Christine.

masateesh · Our kernel verison 5.15.67. is this lf-lf-6.6.3_1.0.0 will work ?

Hi, @masateesh

Sure, this driver supports Linux kernel from 2.6.32 to 6.6.2.

Hi Christine,

I have successfully compiled and generated moal.ko & mlan.ko

these modules I have placed /lib/modules/5.15.67/extra/

& /lib/firmware/nxp/sdiouartiw416_combo_v0.bin placed wifi_mod_para.conf

after I used modprobe moal mod_para=nxp/wifi_mod_para.conf to load module But I have observed an issue.

modprobe: ERROR: could not insert 'moal': Invalid argument

Even I tried insmod moal.ko mod_para=nxp/wifi_mod_para.conf

insmod: ERROR: could not load module moal.ko: No such file or directory.

Regards,

Sateesh

Christine_Li

Hi, @masateesh

Please make sure you are using the correct Linux kernel 5.15.67 tool chain and related source environment path when you compile Wi-Fi driver.

Also the KERNELDIR should be correct.(With Linux kernel 5.15.67 after compiled kernel Image).

For example:

KERNELDIR ?= ~/linux-source-code/L5.15.67_1.0.0/linux-imx

source /opt/fsl-imx-xwayland/5.4-zeus/environment-setup-aarch64-poky-linux

make

One of above info is incorrect, it will cause this error.

You can also use:

file mlan.ko

this command to check what is the mlan.ko file type to see whether is correct.

Best regards,

Christine.

masateesh

Thank you Christine for quick response.

Actually previous my binary not fully copied. due to this reason I have faced problem.

I have updated latest binaries but still I see this above issue.

Christine_Li

Hi, @masateesh

Did you only update the FW to latest one? or also update the driver to latest one?

Can you please help to provide me your full dmesg logs like before?

And, as I mentioned before, I don't think these IOCTL prints have influence to Wi-Fi function.

Also, in your previous comments, I checked your logs, it show that connection has been successfully created.

These IOCTL prints means there are some commands which sent from upper application layer, our FW side doesn't support to response. But actually it doesn't effect Wi-Fi function.

Before we also received similar cases from other customers, and customers also accepted our ideas.

Best regards,

Christine.

masateesh

I have updated both kernel module & firmware binary. Still I have observed same problem.

Hi, @masateesh

Please provide me your full dmesg log, Thanks.
