Hi,
I want to enable SDIO (WiFi) interface from menuconfig but don’t see the option as given in Toradex help page as:
[user@host linux-toradex]$ make menuconfig
Device Drivers --->
[*] Network device support --->
[*] Wireless LAN --->
<*> Marvell WiFi-Ex Driver
<*> Marvell WiFi-Ex Driver for SD8786/SD8787/SD8797/SD8887/SD8897
(4 times)
Do you wish to save your new configuration?
What i get is below:
[*] Network device support --->
[*] Wireless
and there is no Marvell options.
I use Linux2.8B
The Angstrom Distribution colibri-imx7-emmc ttymxc0
Angstrom v2017.12 - Kernel
Colibri-iMX7-eMMC_Console-Image 2.8b6 20190801

Thank you

Hi @neeraj.verma
Which Kernel branch are you compiling?
Best regards,
Jaski
Hi @jaski.tx ,
I use below branch:
repo init -u Index of /toradex-bsp-platform.git -b LinuxImageV2.8
I pulled 3.0 even though I don’t see option as described in support link.

Could you please help me if I am missing something?
You need to get the kernel sources and enable the wifi driver there and not in the Open embedded Environment.
Hi @jaski.tx
I pulled git clone -b toradex_4.14-2.0.x-imx git://git.toradex.com/linux-toradex.git branch and check ‘make menuconfig’ but I don’t see option to enable SDIO.
if I remember correctly I see exactly same options as I was getting in case of bitbake when pulling code using repo init -u Index of /toradex-bsp-platform.git -b LinuxImage3.0 -m default.xml
Could you please help?
Thank You
Neeraj
First of all, you are comparing two different things. The Wifi drivers are backports drivers in our kernel which were dropped in Bsp 3.0. So you won’t see them in the regular 4.1 or 4.9 branch.
So for Bsp 2.8, you would need to follow the instructions of backports integration.
Best regards,
Jaski
I am sorry for the confusion. I followed the steps as Kernel Driver Backports Integration
I have pulled code “git clone git://git.toradex.com/backports-toradex.git” and can see the options in make menuconfig for enable/disable WiFi what I need.
Which path is this? export KLIB_BUILD=~/linux-toradex
but I am seeing build failure and not sure what is the reason. I set env as below:
export ARCH=arm
export PATH=~/gcc-linaro/bin/:$PATH
export CROSS_COMPILE=arm-linux-gnueabihf-
export KLIB=/build/build_wifi

Hi Neeraj
Which path is this? export KLIB_BUILD=~/linux-toradex
This is where you downloaded the sources of the downstream kernel ( 4. x).
export KLIB_BUILD=/build/linux-toradex
Are you sure that this kernel path is correct?
You should correct the path above and then the compilation should work.
Best regards,
Jaski
Hi @jaski.tx
Thank you for your help.
I am able to proceed but now getting another errors.

HI @neeraj.verma
First of all, you don’t need backports for Bsp 3.0 (kernel 4.14).
export KLIB=/build/build_wifi
export KLIB_BUILD=/build/linux-toradex
As already said before, this path might not work as a regular user, you are not allowed to write to this path. You should rather use /home/username/...
Regarding the error, did you setup the Toolchain and exported the variables correctly. You should check this by echo $ARCH.
I tested this on my side and the compilation worked perfectly.
Best regards,
Jaski
Hi @jaski.tx ,
when I built 2.8 kernel, build was okay and I am able to find .ko files below:

Hi Neeraj
According to the dmesg.log the Ethernet and Wireless is present and connected. I don’t get it what is your issue?
Best regards,

Hi @jaski.tx ,
Issues is, I am not able to see interface mlan0 which is Marvell SDIO. Ethernet and wlan0 is known working interfaces in board.
actually I get below error which I noticed when used serial/debug port to see console message. (I was using ssh earlier).

Could you check the output of lsmod? If cfg80211 is not present, then you should load ( insmod) it before.

Hi @neeraj.verma
You have to bring up the Wifi as described here. The device-tree changes are just needed if you have fast SDIO Wifi card. We treated the question about Sdio Wifi Speed here.
