Odroid N2 mainline kernel

[woody]

The default installation of ARM on the Odroid N2 is 4.9.190-2-ARCH. Has anybody switched to the mainline kernel? How is it working? What are the outstanding issues? Any big problems?

I too am looking to upgrade to current kernel, there is some talk on the odroid forums.

Did try that with that "Guide" with 5.3.3 and the Network did not work. AFAIK it does not yet run on Full speed.
With the linux-aarch64-rc 5.4.rc2-1 it did not boot. (bootloop but i have not the right tools here to debug it)
Will look if it will work with the next RC

Thanks for rerouting your experience. That's what I wanted to know. I guess that not many people are running Arch on the Odroid N2.

Please post again when you get a chance to test the next release.

Same guide as before on a fresh installation (only changes <setenv bootargs "root=/dev/mmcblk0p2> for the eMMC and in the mkimage step the changed Kernel version)
Kernel: aarch64 Linux 5.4.0-rc3-1-ARCH did Boot but the network does not work by default

it did work if i changed the network to ipv4 only
/etc/systemd/network/eth.network
$this->bbcode_second_pass_code('', 'Name=eth*

[Network]
DHCP=ipv4
DNSSEC=no
LinkLocalAddresing=ipv4
')
after every boot i need to restart networkd (Could be that this workaround does work for the 5.3 Kernel too)
$this->bbcode_second_pass_code('', 'systemctl restart systemd-networkd.service')

Wayland/Sway
Copied the drm folder to /usr/lib https://dn.odroid.com/S922X/ODROID-N2/Wayland/wayland-drm_arm64.tar.gz
Sway does work but it uses a lot of CPU for every small movement on the screen

Not sure if the onboard Audio/Audio over HDMI is allready usable on mainline but i did not really try to get it to work
