Hi
I am working on an Apalis iMX6 Quad 2GB board and I am unable to connect a wifi dongle to the board.
The wifi dongle is the Edimax N150.
How do I install the driver for the Edimax N150 in the Apalix iMX6 board?
Regards
Jy.Teh
hi @jy.teh
Welcome to the Toradex Community!
Could you provide the version of the hardware and software of your module? Which carrier board are you using?
Did you try the dongle on a regular Bsp Image (for example 2.8b6) and check if the dongle is working? If it is not working, then please share the complete dmesg log in a file?
Thanks and best regards,
Jaski
I am using a Toradex Apalis iMX6 Quad 2GB attached to an Apalix Evaluation Board.
I tried the stable built downloaded from here
When i tried the latest built i got the following error:
" reading uImage
** Unable to read file uImage **"
Please find the log trace from the start of the board with the stable built.
The dmesg starts from line 592
When i tried the latest built i got the following error: " reading uImage Unable to read file uImage "
Could you stop in U-Boot during booting sequence and do the following command:
env default -a
saveenv
and then reboot the module.
I tried the stable built downloaded from here https://developer.toradex.com/knowledge-base/flashing-linux-on-imx6-modules#Flashing_from_Scratch
As an alternative to this, we recommend you to use the Toradex Easy Installer to install the Image on the module.
Thanks and best regards,

Hi Jaski
Please find the logs attached.
The logs are collected with the latest build. (Apalis-iMX6_LXDE-Image 2.8b6.184 20190401)
When i plug the wifi dongle it detect as a bluetooth device, in connmanctl there is no wifi visible.
How do i enable the wifi?
The firmware of your dongle is not included in the regular bsp image, you need to copy this from the host to your module.
Best regards,
Jaski
how do I do this?
Where could i find the firmware for my dongle?
I tried following the how to build the kernel backport here ( Kernel Driver Backports Integration)
But still could not get the wifi to work.
Where could i get the firmware for my dongle?
If you insert the dongle in the usb port of your host, then you should see, where the file is located on your host. You can just copy this.
What file type is the firmware for the dongle?
Which location do i copy the firmware in my module
You should look for this file on your host: rtl8723b_fw.bin. This file should be copied to the folder /lib/firmware/rtl_bt/rtl8723b_fw.bin on the module.
i mange to copy over the firmware files of the modules.
Currently the bluetooth part of the dongle is working, but the wifi is still not working.
Once i plug in the dongle, the BT firmware is loaded but nothing is being done for the wifi.
Attached is the log file.

Thanks for this Information.
Could you provide the output of lsusb on the module with Wifi Dongle connected to the module?
Additionally please share the complete dmesg log in a file ( dmesg > dmesg.txt ) after connecting the Wifi Dongle to your host?
lsusb shows the dongle have been connected.

please find the log files attached.
There are 3 files : full.txt, dmesg.txt and lsusb.txt
From the logs you could see that I plug in the Edimax Dongle (the one that i would like to use with the board) to the Apalis board and immediately the bluetooth is enable. We could see that some bluetooth files are being called. But there is nothing on the wifi portion.
Next i removed the Edimax Dongle and try it with another wifi dongle (line 1140), but nothing wifi related happened. When i see the technologies from “connmanctl” i could only see ethernet.
hi @jaski.tx
Hope you find something in the logs given. 
Are there any more logs that you require that might help you with your investigation?
hi @jy.teh
Thanks for the files. Regarding the dmesg.txt, I would need the dmesg log for your Host and not the module.
Further, our FAE ( @alvaro.tx ) for South Asia is working on this topic.
