How to compile code for 88W8977 (PAN9026 module) to work with i.MX8

[sebonghm]

Hi,

I've managed to finally get a source for compiling drivers

(https://community.nxp.com/t5/Wireless-Connectivity/How-and-where-to-download-wifi-bluetooth-driver-f...)

I have also followed instructions of how to make the driver from post:

https://community.nxp.com/t5/i-MX-Processors/PAN9026/td-p/1319127

The package given by vendor:

SD-WLAN-SD-BT-8977-U16-MMC-W16.68.102.p9-16.26.102.p9-CS4X16710_V2-MGPL.zip

On compile, I had multiple errors, with the chief blocker seeming to come from "wlan_src/mlinux/moal_main.c:4519:57: error: 'struct wireless_dev' has no member named 'current_bss'"

Please advise if there is a required version of kernel to get the driver compiled and or a different version of the driver.

The compile details

Hi, @sebonghm 

From your attached driver version's Readme, I found this driver code supports Linux kernel from 2.6.32 to 5.15.5.

But from your given logs, I think you are using Linux kernel 6.1.y. Am I right?

=====

make
make -C /media/seb/2a164241-f27f-4bad-857d-17f1b5d77a44/imx-yocto-bsp/build/tmp/work/imx8mp_lpddr4_evk-poky-linux/linux-imx/6.1.y+gitAUTOINC+770c5fe2c1-r0/build M=/home/seb/PAN9026_driver/wlan_src modules

====

So the Linux kernel version is out of the Wi-Fi driver support limit.

Please change the Linux kernel version to this limit:  Kernel 2.6.32 to 5.15.5.

I am so sorry about the inconvenience.

Best regards,

Christine.

Hi Christine,

I am trying to get this module to work with the i.MX8 eval board and the default yoctobuild for the i.mx8 is at kernel version 6.1. Is there a version of the driver that is updated to support kernel 6.1? Otherwise is there plans for the update?

Thanks

Regards

Sebastian

Hi, @sebonghm 

I am sorry for the inconvenience.

This is the latest release on our website because 88W8977 is an old Wi-Fi chipset, the release and maintain is not sufficient as the newer products.

You can download our I.MX8 prebuilt image through below link:

https://www.nxp.com/design/design-center/software/embedded-software/i-mx-software/embedded-linux-for...

Choose the Linux kernel version you prefer, and choose the correct product which is in your hand.

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

Best regards,

Christine.
