Can you tell which file I should copy? should I copy all the files?
BTW here is my lib/firmware now:
ls /lib/firmware/brcm
BCM43430A1.hcd brcmfmac43430-sdio.bin brcmfmac43456-sdio.bin
BCM4345C5.hcd brcmfmac43430-sdio.txt brcmfmac43456-sdio.txt
Zero cannot connect to wifi
I have not changed anything yet but wifi is back after rebooting. it seems it load fmac43456-sdio if it cannot find fmac43456-sdio.radxa,zero.txt , but this does not happen consistently.
Here is new dsmeg:

I change fmac43456-sdio.* to fmac43456-sdio.radxa,zero.* now it can load the firmware. hopefully it can work consistently.
still not stable…
Can you be more specific on “not stable”? Did it disconnect? Was the device gone? Can you restore functionality after ifupdown or you need to reboot? Hard to tell what’s the problem here.
Every time I power the board, there is 40% chance system can load the firmware so I will have wifi working. Other 60% time the board cannot load the firmware so I have to reboot system.
Even after renaming the file?
yes, I actually copied them instead of renaming them. Here is the firmware folder:
ls /lib/firmware/brcm
BCM43430A1.hcd

BCM4345C5.hcd

brcmfmac43456-sdio.radxa,zero.txt

Can you try rmmod brcmfmac && modprobe brcmfmac a few times to see if that can bring wifi back?
Hi, after run the command wifi works. Here are the outputs:

BTW, I noticed there is new image released in github. Do I need to reinstall the latest image to get the latest update or just run apt update && apt upgrade?
I also have following message pops up for several times:
[ 6360.535400] mmc2: tuning execution failed: -5
Could you tell me what is going wrong?
Thanks
Currently our apt repo is having some technical issue. After we clear it you can update with apt.
@Jing_Guo @spikerguy @stuartiannaylor To build Radxa mraa on Manjaro, you need to apply the following patch before building: curl https://github.com/eclipse/mraa/commit/aaa0a5cd4e401bde4fb3691dd4e6c70a5c61e031.patch | git apply
That repo is maintained by @Stephen and @ken so I’m not touching it for now. I’ll make sure Zero 2’s mraa is merged upstream though (just realized I need to write this piece as well 
).

The eclipse one seems a better bet as all brands I guess can contribute to that and maybe we might just get distro binaries.
Thanks for the patch though as we can compile the Radxa one.
Did you mention Zero2… 
fingers crossed soon.
Hope @Jing_Guo is sorted one way or another now think it was just dtbo availability for other distro’s?
I have added it to the PKGBUILD
Users can get it using the following:
git clone https://github.com/spikerguy/mraa
cd mraa
makepkg -scri
Test it out and let me know.

Hello, I have a radxa zero (512MB ram, no emmc) with AP6212. Is it possible that it is restricted to wifi channels 1-11?
The plain “mraa” AUR package is long out of date and doesn’t contain recent RADXA source, So I created a version that does. I also added support for aarch64, armv6h and armv7h, so it will work on raspberry pi’s etc.
Tested and confirmed working on Rock Pi 4b + Manjaro, will test ZERO once mine arrives…
