requesting IW416 NXP Driver

[naresh_nakka]

Hi ,

i am working on wifi (iw416 chip -  LBEE5CJ1XK )

Interface : wifi - sdio , BT - uart .

could you please share the wifi-bt driver and firmware ?

also please mention what are changes required to enable it in the kernel ?

Thanks,

Naresh

[naresh_nakka]

Hi Christine , 

Thanks for your quick response. 

now , moal.ko is able to load .

actually the issue with other drivers (rtc/humidity sensor/charger ) .so once i disabled from kernel , moal.ko is able to load .

but bluetooth getting below issue , couldd you pleasee help me on this .

Hi, @naresh_nakka 

Great job!

Is it ok for you to create a new thread to discuss about the Bluetooth failure?

This thread has too long history, and we always suggest customers to track one issue in one thread. It will also be very helpful for our future reference.

Sure, even on the new thread,  I will also still reply you at the first time as this one.

Thanks for your corporation.

Best regards,

Christine.

[naresh_nakka]

Sure , Christine.

But with the below steps i am able to pair a BT device . 

please find below steps .

[Christine_Li]

Hi, @naresh_nakka 

Great job.

It seems like the Bluetooth also works on you side.

So until now, Bluetooth and Wi-Fi driver can work well. 

Before connect command and after pair command, please trust the device to have a try.

Like below:

pair 30:KK:7D:BF:D4:2A

trust 30:KK:7D:BF:D4:2A

connect 30:KK:7D:BF:D4:2A

For other topics please create a new case to us.

Thanks for your corporation.

Best regards,

Christine.

Thanks christine for your support .

i will create new case for file trnasfer issue

Hi, @naresh_nakka 

From your given log, I see that:  "Please add cal_data_cfg for 8887/8977/8997/8987/8978"

So please add cal_data_cfg parameter when you load the Wi-Fi driver, like below in /lib/firmware/nxp/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
}

Or directly load like this:
insmod moal fw_name=nxp/sdiouartiw416_combo_v0.bin cal_data_cfg=none ps_mode=1 auto_ds=1 host_mlme=1

Please have a try with this parameter and if still have problem, share me your full dmesg logs to check further.

Best regards,

Christine.

[Christine_Li]

Hi, @naresh_nakka 

Thanks for your feedback. Can you please help check whether has below configurations in your board /lib/firmware/nxp/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
}

And then try to load Wi-Fi driver like below as our module partner CEL's Ryan's suggestion.

insmod moal.ko mod_para=nxp/wifi_mod_para.conf

 If still have any problem, please share your full dmesg logs for further checking.

Regards,

Christine.

[naresh_nakka]

Hi Christine ,
Thanks for your help.
i have loaded with below command
insmod moal.ko cal_data_cfg=none
then wifi is up.

could you please give steps how to enable bluetooth in the kernel and device tree configuration of node ?

[Christine_Li]

Hi, @naresh_nakka 

For Bluetooth driver, it depends on your Linux kernel version:

Before Linux kernel 6.1.22, we use the default Bluetooth UART driver in Linux Kernel BSP. You can compile it with "make menuconfig" under your Linux kernel BSP directory. Make sure BT_HCIUART is enabled.

After Linux kernel 6.1.22, please see below link for detailed reference:

https://community.nxp.com/t5/i-MX-Processors-Knowledge-Base/Bluetooth-NXP-UART-Driver-Linux-BSP-6-1-...

And also, this thread topic is requesting for IW416 NXP driver, right now I have shared to you our Wi-Fi driver GitHub download link and you have compiled and loaded successfully and also shared above Bluetooth driver information. Can you please help to close this thread and create a new one to discuss new queries? This thread has been closed 2 times because of delay reply. It has been open for too long time.

Thanks for your corporation and have a nice day~

Best regards,

Christine.

[rtwheato]

Naresh,

try:

insmod moal.ko mod_para=nxp/wifi_mod_para.conf

(or whatever the path is to your config file.  it looks first in /lib/firmware/ so the path above is equivalent to /lib/firmware/nxp/wifi_mod_para.conf)

If you're looking for more support or better performance, CEL has a iw416 based module too (CMP9010).

best,

-ryan

[naresh_nakka]

Hi Christine,

Thanks for your quick response,

what might be the flag to select  in menuconfig of kernel  ?

Thanks,

Naresh.

[Christine_Li]

Hi, @naresh_nakka 

For ubuntu, I don't think need to modify any special configurations in menuconfig, but please make sure cfg80211 is chosen as the basic option of Wi-Fi.

Please firstly make with default configurations.

For our I.MX8 series product, I know we have to use  make  imx_v8_defconfig.

Best regards,

Christine.

[naresh_nakka]

Hi Christine,

Thanks for information.

please find below below details.

kernel version :  

VERSION = 6
PATCHLEVEL = 1
SUBLEVEL = 33
platform : 20.04.1-Ubuntu

May i know what is the kernel flag for iw416 in kernel source  code ? as well as what is the compatible name in dts file ?

is it compatible name is sd8978 ?

Thanks,

Naresh.

[Christine_Li]

Hi, @naresh_nakka 

Thanks for your feedback.

For mass market FP92 drivers, it is compatible to our several Wi-Fi chipsets including IW416.

It means, after download from this git hub, compile it with your cross-compile tool chain, you can directly use. The only one point you need to pay attention to is choose correct tag, such as, you are using Linux kernel :6.1.33, you can choose our tag: lf-6.1.36_2.1.0 

Christine_Li_1-1700103011833.png

The differences between different Wi-Fi chips are firmwares.

You need to download IW416 firmware and wifi_mod_para.conf, then put it to your /lib/firmware/nxp/ directory.

Christine_Li_2-1700103195752.png

For compiling driver, you can refer to below my cross-compiling 88W8987 driver method:

====================

编译Driver：

nxf93258@lsv07252:~/wifi-drivers/marvell-sd-uapsta-8987$source /opt/fsl-imx-xwayland/4.14-sumo/environment-setup-aarch64-poky-linux

nxf93258@lsv07252:~/wifi-drivers/marvell-sd-uapsta-8987$ make -j8

===============

Best regards,

Christine.

[Christine_Li]

Hi, @naresh_nakka 

I saw you are using Ubuntu, then I think you can directly compile without configuring cross-compile toolchain.

You can directly use "make -j8" command to compile driver.

Best regards,

Christine.

[Christine_Li]

Hi, @naresh_nakka 

You can download our IW416 driver from our github:

git clone https://github.com/nxp-imx/mwifiex.git 

git tag // to list our tags according to your Linux kernel version.

git checkout -b TAG(the tag you chose)  such as: git checkout -b lf-6.1.1_1.0.0

And I think Firmware is also needed for you, please download Firmware from our github:

 git clone https://github.com/NXP/imx-firmware.git 

git tag  // to list our tags according to your Linux kernel version.

git checkout -b TAG(the tag you chose)  such as: git checkout -b lf-6.1.1_1.0.0

After download, you need to cross compile according to your kernel BSP with your cross compile tool chain.

Please let me know your platform, kernel version and your host MPU/MCU for further support.

Best regards,

Christine.
