Hello

Hello,

In fact I am using a PAN9026 wifi module on my IMX8 card.
with ubunto 4.14.78.
I have correctly configured the linux kernel and I created an image based on this configuration but I still have this message when inserting my wifi module.

Hello @Amine_Ferchichi ,

It means there is no 88W8977 driver (PAN9026 module) in your system.

It's driver can be downloaded from our website if you have signed NDA and been authorized.

---About the pan9026(88w8977 chip) driver, you can also ask for help from Panasonic FAE.

---On how to compile it and integrate it to i.MX8 + linux bsp

you can refer to the link:

Have a good day!

Hello,
Thanks for your feedback.
But in fact my problem is in version 4.14 ....
on the other hand in version 5.4.21_2.1.0 I manage to integrate the driver of my divice PAN9026.
By that in version 4.14 I find in the build lo folder of my driver.
under build-x11-pico-imx8 / tmp / work / imx8qxpc0mek-poky-linux / linux-imx / 4.14.98-r0 / build / drivers / net / wireless / marvell / mwifiex

I have correctly configured the linux kernel and I created an image based on this configuration but I still have this message when inserting my wifi module.

Hi Amine_Ferchichi ,

Even if your kerenl is 4.14.98, compiling and loading driver are the same as that of L5.4.21.

Assume you are using imx-yocto-bsp and linux host it ubuntu 18.04.

1. compiling your board board bsp in yocto.

2. export cross-compiling toolchain from yocto and install it to /opt directory

On how to export the toolchain, refer to i.MX_Linux_User's_Guide.pdf.

4.5.12 How to build U-Boot and Kernel in standalone environment

3. downloading 8977 driver from our website if you have been authorized

after decompressing it, you will get 5 .tgz file and FwImage directory.

SD-BT-8977-U16-MMC-16.26.10.p98-C4X14114_V2-GPL-src.tgz
SD-BT-CHAR-8977-U16-MMC-16.26.10.p98-C4X14114_V2-GPL-src.tgz
SD-UAPSTA-8977-U16-MMC-W16.68.10.p98-C4X16679_V2-app-src.tgz
SD-UAPSTA-8977-U16-MMC-W16.68.10.p98-C4X16679_V2-MGPL-src.tgz
SD-UAPSTA-8977-U16-MMC-W16.68.10.p98-C4X16679_V2-mlan-src.tgz

Using these commands to decompress them at the current path.

# tar zxf SD-UAPSTA-8977-U16-MMC-W16.68.10.p98-C4X16679_V2-app-src.tgz

# tar zxf SD-UAPSTA-8977-U16-MMC-W16.68.10.p98-C4X16679_V2-MGPL-src.tgz

#tar zxf SD-UAPSTA-8977-U16-MMC-W16.68.10.p98-C4X16679_V2-mlan-src.tgz

#tar zxf SD-BT-8977-U16-MMC-16.26.10.p98-C4X14114_V2-GPL-src.tgz

# tar zxf SD-BT-8977-U16-MMC-16.26.10.p98-C4X14114_V2-GPL-src.tgz

SD-UAPSTA-BT-8977-U16-MMC-W16.68.10.p98-16.26.10.p98-C4X16679_V2-MGPL will be created.

# cd SD-UAPSTA-BT-8977-U16-MMC-W16.68.10.p98-16.26.10.p98-C4X16679_V2-MGPL

# ls

mbtc_src mbt_src wlan_src

Three directories can be found. mbt_src is for bluetooth, and wlan_src is for wifi

4. entering into wlan_src directory of driver.

# cd wlan_src

#source /opt/fsl-imx-xwayland/4.14-sumo/environment-setup-aarch64-poky-linux

#export KERNELDIR=/home/weidong/imx-yocto-bsp-4.14.98/build-xwayland/tmp/work/imx8mmevk-poky-linux/linux-imx/4.14.98-r0/build

(this is the directory of mine, for yours, you should check and change it to yours)

# unset LDFLAGS

# make

you will get 2 .ko files: mlan.ko & sd8xxx.ko .

copy these 2 files and firmware( sd8977_ble_v2.bin sd8977_bt_v2.bin sd8977_wlan_v2.bin sdsd8977_combo_v2.bin) to board ( /home/root)

5. On board

# cd ~/

# mkdir /lib/firmware/nxp

# cp ./*.bin /lib/firmware/nxp

# insmod mlan.ko

# insmod sd8xxx.ko 'drv_mode=7 ps_mode=2 auto_ds=2 cfg80211_wext=0xf fw_name=nxp/sdsd8977_combo_v2.bin cal_data_cfg=none'

Then use ifconfig -a to check wifi interface.

up to now, loading driver is done.

Try it, please!

Have a good day!

regards,

weidong

Hello

The insertion of PAN9026 driver in the image based on 4.14.98.2.3.0 is done.

Here is the log when i insert drivers:

root@imx8qxpc0mek:~# insmod mlan.ko

The probleme is that after the insertion of drivers, we got an error on the configuration of the board as an access point :

step1)root@8qxpc0mek:~# ifconfig mlan0 up

step2)update /etc/wpa_supplicant.conf with the AP parametres.

step3)root@8qxpc0mek:~# sudo wpa_supplicant -B -i mlan0 -c /etc/wpa_supplicant.conf -D wext

Successfully initialized wpa_supplicant

rfkill: Cannot open RFKILL control device

and when i brone up my mlan0 interface

root@imx8qxpc0mek:~# ifconfig mlan0 up

[ 242.099918] IPv6: ADDRCONF(NETDEV_UP): mlan0: link is not ready

and i see that the rfkill device is missing, when i try to execute rfkill list, this error message appaire

rfkill: /dev/rfkill: No such file or directory.
