Drivers for RTL8812au on ODROID M1

[Nicola Zilio]

Dear all, 

I have recently acquired an ODROID M1 board and flashed Armbian 24.5.3 on it to replace my old XU4 running Armbian 24.5.1. I've managed to port everything from the old XU4 to the new M1 except for two WiFi dongles. They worked just fine on the XU4 but the M1 just doesn't want to recognize them, I can see them when I run `lsusb`

but I get no wifi interfaces. 

 

Does anybody know what the problem could be?

 

Thanks in advance!

Have you tried installing armbian-firmware-full?

[Nicola Zilio]

Yes

 

armbian-firmware-full is already the newest version (24.5.1)

 

though I am not sure whether I need to do something specific after having installed that.

[Nicola Zilio]

Flashing https://armbian.hosthatch.com/archive/odroidm1/archive/Armbian_23.11.2_Odroidm1_jammy_current_6.1.68.img.xz did solve the issue.

 

However, running

 

apt update && apt upgrade

 

reintroduced the problem. Therefore, it would appear that some updated packages breaks compatibility with these WiFi dongles.

https://github.com/armbian/build/blob/main/config/kernel/linux-rockchip64-current.config#L3541
It seems they got disabled here https://github.com/armbian/build/pull/6202

 

Size reason? Perhaps they don't compile? I have open a PR and lets see what others say about.

[Nicola Zilio]

Ok, so that means that, for now, I could simple hold that one package back (apt-mark hold linux-dtb-current-rockchip64 and/or linux-image-current-rockchip64) and in theory I should be good?

Yes. Or update, install headers and try to build this driver via DKMS. But it might be challenging ...

[Nicola Zilio]

Yes, it does seem to be challenging. I'm happy to wait for a fix :).
