There is gpio-utils which is in repo.
Zero cannot connect to wifi
Nothing returned on:
dmesg | grep wlan0
Yeah it was just an example of how to grep what is relevant to make a copy & paste a little more concise.
I would have a look through dmesg to see if you can see anything that might look relevant and use grep just to grab a copy & paste to here than a complete dmesg.
Dunno even if wlan0 might be the name it assigns as forgot what the naming convention is.
OK. I had to store the messages to a file and then get them off my sd card.
Hereâs the results of - sudo dmesg | grep brcm

Device-2: dwmac driver: N/A
And, the Radxa Zero doesnât have emmc.
This is not the chip which is advertised.
Bit confusing.
While 43430 = ap6212
I cannot find Zeroâs SKU list to understand the difference in Wifi Chip.
Found it here: Zero SKU
So non-emmc (512mb/1gb RAM) version have AP6212 wifi chip. I will add it to the package.
Thank you for coordinating with us otherwise I wouldnât have known this fact.
I have ap6256 which is 43456
To get ap6212 firmware please do this.
sudo pacman -R ap6256-firmware
sudo pacman -S kvim1-firmware
Once it is installed then run this command.
sudo cp /usr/lib/firmware/brcm/brcmfmac43430-sdio.txt /usr/lib/firmware/brcm/brcmfmac43430-sdio.radxa,zero.txt
sudo reboot now
Hopefully you should have wifi with this.
Good Luck.
Youâre welcome. Thank you for your patience and help.
This is what happened. I go the same kind of error trying to do a system upgrade earlier via wifi dongle.

Lol thats a lazy maintainers key 
its renewed but you seem to have old pkg.
Please do this.
sudo pacman -Syyu kvim1-firmware
Got the same error.
2mins let me check.
Ok it is indeed updated, should have updated local keyring but it didnât
run this please
sudo pacman-key --refresh-keys
this will take some time.
then
sudo pacman -S kvim1-firmware
and follow the copy command.
After the Proceed with installation? [Y/n] it finds the same Furkan Kardame trust error. It asks Do you want to delete it [Y/n] and either Y or n says Erros occured, no packages were upgraded.
did you run this ?
maybe update gpg files too.
gpg --refresh-keys then try sudo pacman-key --refresh-keys command
I tested it myself as I had the same error but after getting the updated keys I was able to install the pkg.
Did the gpg --refresh-keys.
On doing sudo pacman-key --refresh-keys, every name had the same error. This is just the tail end. Signing off for today. Thanks for the help. Iâll check back tomorrow.

@jack Can you help me on the Ubuntu wifi issue? I tired ubuntu 20220207 server version again, the wifi still donât work. Yet Manjaro works fine. I really need mraa on zero some of my projects reply on mraa.
Do you happen to run the above configuration? Also can you post your dmesg after boot.
Hi,
My question is not related to Manjaro, Manjaro works great with wifi. The problem is the latest Ubuntu from radxa repo cannot detect wifi hardware. I will reinstall ubuntu and update dmesg output.
Yes I understand but those questions still apply. I need to know your hardware configuration and the kernel message before making further judgement. Also make sure to install from https://github.com/radxa/debos-radxa/releases/latest
The board is powered by 5V pin Here is the dmesg:

This seems to be your issue. Can you try download the file from here and place it in your firmware folder, and check if that fixes your issue? If that works Iâll check if that was missing from our build system.
