There is no wifi after .hddimg is installed

likku

My device is https://www.aaeon.com/en/p/iot-gateway-ups-gws01 and I follow https://github.com/AAEONAEU-SW/meta-up-board/tree/sumo to build a .hddimg.
However, there is no wifi interface in ifconfig and "iwlist wlan0 scan" is not working.

Thanks.

You'll need a custom kernel config to compile the ath10k drivers, and then add the firmware to your image for the 10k chipset, the package name is: linux-firmware-ath10k

You can add it by editing whatever image definition you are using with the a line like this:

IMAGE_INSTALL += " linux-firmware-ath10k"

Kernel config lines can be added to the this file locally if you don't have your own bbappend file setup for custom kernel configurations . https://github.com/AAEONAEU-SW/meta-up-board/blob/sumo/recipes-kernel/linux/files/up-board-user-config.cfg

You can find the kernel config lines here
https://wireless.wiki.kernel.org/en/users/drivers/ath10k/configuration

DV01D

I did forget you will need to clean the sstate of your kernel first to pick up the change to your kernel config, then rebuild your image. This command should do it for you:

MACHINE=up-squared bitbake -c cleansstate virtual/kernel

DCleri

the wifi on that product is optional.

Are you sure you got the one with the WiFi module installed?

Hi DCleri,

Thanks for your reply.
I use a bootable USB stick to boot "ubuntu" for USB and there is a wifi interface (wlp4s0) in ifconfig.

can you please identify the type of wifi card using dmesg?

likku

Hi DCleri,

Thanks for your help.
The dmesg of yocto and ubuntu are attached.
In ubuntu_demesg.txt, the log listed below may be related to wifi.

[ 32.303272] ath10k_pci 0000:04:00.0: qca6174 hw3.2 target 0x05030000 chip_id 0x00340aff sub 11ad:0808

BTW, the model of my device is "UPS-VKIT01-GWS01X7-A20-0464".

Cheers,

Thanks @likku

So the WiFi is working correctly on Ubuntu? Can you confirm?

We will review why with the Yocto image the WiFi firmware is not loaded and we will come back to you asap
