Does the Linux 5.10.72_2.2.0 Demo Binary include the 88W8987 driver?

[HiroakiOkoshi]

I simply want to set up an evaluation environment for 88W8987 (JODY-W2). The materials I have are as follows. (By the way, in the environment of zeus, YOCTO is built and it works.)

1. i.MX6Qsabresd Board
2. EVK-JODY-W2

The downloaded binary is below.

LF_v5.10.72-2.2.0_images_IMX6QPDLSOLOX.zip

I run to the imx6QsabreSsd board with the following command.

>uuu -b emmc_all u-boot-imx6qsabresd_sd-optee.imx imx-image-full-imx6qpdlsolox.wic
uuu (Universal Update Utility) for nxp imx chips -- libuuu_1.4.165-0-ge10b026

Success 1    Failure 0


1:3      8/ 8 [Done                                  ] FB: done

The first thing that surprised me when I started it was that /lib/modules/5.10.72-lts-5.10.y+ga68e31b63f86 haven't   88W8987 module.
There is a 88W8987 firm in /lib/firmware/nxp/.

I've tried the following just in case, but I don't see any signs that modules or firms are being read.

# modprobe moal mod_para=nxp/wifi_mod_para_sd8987.conf

Does the Linux 5.10.72_2.2.0 Demo Binary include the 88W8987 driver?

According to the document (SCR-5.10.72-2.2.0.txt) included in LF_v5.10.72-2.2.0_images_IMX6QPDLSOLOX.zip, the following notation is given, so it was judged that the driver was included.

I tried to build 5.10.72-lts-5.10 YOCTO simple(repo sync & bitbake), but after all, the Driver of 88W8987 was not included.
Currently, I want to use NXP drivers, so I'd like to somehow create the latest environment for this board.

What should I do?

Hi @HiroakiOkoshi ,

i.MX8MN-EVK board supports 88W8987 hardware, so it's default demo image includes 8987 driver.

for i.mx6q serials, you should select it in linux kernel. 

then use modprobe to load it.

Have a good day!

Regards,

weidong

[HiroakiOkoshi]

Do you mean this selecting?

Thanks.

[weidong_sun]

Hello @HiroakiOkoshi ,

sorry, correct it.

In kernel, it's Marvel driver, not latest one. below is an example for getting driver:

--driver
#git clone http://source.codeaurora.org/external/imx/mwifiex.git
#git tag
#git checkout lf-5.10.72_2.2.0

--firmware
https://github.com/NXP/imx-firmware/tree/lf-5.10.72_2.2.0/nxp

you can select related driver and firmware according to your kernel version. and compile it separately.

Have a good day!

Regards,

weidong

[HiroakiOkoshi]

Thanks.

I knew that this file could be obtained with this command, but I avoided it because it is not a YOCTO recipe.
I tried running it with imx6qsabresd, but the error code was as follows because various environments are different in the first place.

root@imx6qpdlsolox:/usr/src/mwifiex/mxm_wifiex/wlan_src# make build

make: *** [Makefile:565: default] Error 2

In other words, in YOCTO's HOST environment, I have to carefully set the compiler and linux source directory and build them.

understand. I will try it.

I tried it, but it doesn't fit.
Give up and think about other things.

[weidong_sun]

Hello @HiroakiOkoshi ,

See Below steps, please!

1. exporting cross-compiling toolchain using Yocto

open i.MX_Linux_Users_Guide.pdf, and search standalone, you will see how to export the toolchain.

2. installing the toolchain(.sh file) to /opt directory.

3. using source command to configure environment, like below

enter into wifi's wlan_src subdirectory, and run :

#source /opt/fsl-imx-fb/5.4-zeus/environment-setup-cortexa9t2hf-neon-poky-linux-gnueabi

[Note]

above is mine , yours should be a little different.

4. setting KERNELDIR

It is in yocot build(tmp/work....) directory, 

5. run make build or make

after compilation is done, mlan.ko & moal.ko are generated.

these 2 files are drivers.

Have a good day!

Regards,

weidong

[HiroakiOkoshi]

Thanks weidong.

However ...

1. I could build driver.(*1)
2. I can't find sd8987.ko in bin_wlan directory.(*1)
3. Building from mwifiex generated mlan.ko and moal.ko.   mlan.ko and moal.ko were prepared.(*2)
4. If I think about another point of view, I suspect that there is a problem with the device tree selection, not with the driver build.
5. I checked dmesg and it seems that sdio is not found. (*3)
6. If so, which of should I select the dtb file, JODY-W2 (88W8987) is connected to SD3 of imx6qsabresd. (*4)

Hi All.

The problem has been solved.

The root cause was less contact SDIO connector.
Sorry for the misguided discussion

"Does the Linux 5.10.72_2.2.0 Demo Binary include the 88W8987 driver?"

"Yes!!!!"
