Wifi-Driver rtl8812

I try to install the package rtl8812au-dkms and it fails with:

Same issue, if I try to compile the driver manually:

Which package I missed to be installed, that this function may be available. With the original Odroid M1 Ubuntu LTS 22.04 and Linux 5.19 this package could be installed.

 

Thx

You need to adjust sources that will be compatible with kernel 6.0.y If you know what needs to be done, then it looks like this: https://github.com/aircrack-ng/rtl8812au/pull/1008/files some of ours https://github.com/armbian/build/tree/master/patch/misc Can be few hours of work ... 

[nikodemus]

Your are right, the aircrack-version is not Linux 6.1 ready. The rename of the prandom_u32 is not the only thing.

I found working drivers at https://github.com/morrownr (8812 and 8821).

 

thx

Thanks for the referance.

 

I did not get the Odroid Wifi 5A working, but the 5B did work (after an usb-modeswitch, so I still have to add an udev-rule).

[specs]

Small update: the 5B (8821cu) is at boot recognized as cdrom, which prevents the M1 from booting.

Can the M1 somehow be configured to ignore an USB cdrom?

I usually start this way:
https://www.google.com/search?q=wifi+recognized+as+cd+rom

then integrate it into our kernel or share on forums.

Its not a problem specific to M1 nor Armbian.

[specs]

The U-boot from hardkernel does not boot from USB when in skip_spiboot mode.

An SD-card with the hardkernel image boots fine with the wifi adapter attached, even with  skip_spiboot.

 

Therefore tripping over the cd-device during boot is a very specific Armbian problem.

The problem probably starts with the pre-release bootstrap, after the initial boot phase and before switching to nvme partition.

 

A wifi adapter which identifies itself as a cd-device is a problem in itself, of course.

With a working spiboot for the M1, it should be managable though.

Common to all modern kernel based Linux distributions that does not chain load with propriety kernel? Armbian is a build system that assembles and provide ready to run Debian like / based OS for single board computers.

Yes of course, but open source boot loader is not done yet, dunno what is the status ATM, while we decide to not provide Armbian images with proprietary vendor (Petit)boot / kernel.

 

I don't know if there is a solution. Only a workaround - that you use some other WiFi dongle.
