Timelines to update odroid-c2 kernel to a modern and supported branch?

[graysky2]

3.14.79 is currently EOL'ed upstream. Are plans and timelines established to transition to a newer lts kernel for the ODROID-C2? I've read rumors (can't find links) that the 4.4 branch was under development. I don't see any branch here that substantiates this. Thanks!

please see http://linux-meson.com/

I don't see a timeline on http://linux-meson.com/.

I agree, this is desperately needed, the kernel is just really getting very long in the tooth. And there are just a lot of issues with it that have been fixed in the newer releases. For instance, I recently ran in to an issue where a lot of dmcrypt file ops pretty much bring down the whole machine. This is a know issue and has been fixed a long time ago, but that fix is not available on C2 due to the very old kernel version.

@konradsa Well, then the "timeline" will be "it's ready, when it's ready". From what I get, it'll be possible to run a headless server on a C2 with 4.10. The general situation (I hope this is known) is that the SoC vendor Amlogic is providing kernel sources of a specfific version for customers and that is, what's used as a base by Hardkernel.

@mmoll - Thanks for the info. I'm ready to stop using my C2 all together since I cannot get the bridge ethernet to work with lxcs (Arch ARM or Ubuntu). I am very interested in running a headless server with a more recent kernel. Have you personally done this or just believe it to be possible?

[mmoll]

@graysky2 see http://rglinuxtech.com/?p=1880 - I have no idea of lxc, but I'm using a C2 with 3.14 kernel and a bridge, with brigdes eth0 and qemu-kvm VMs without any issue.

[konradsa]

I would love to run a headless C2 with 4.10 as well. So basic instructions on how to do that would be nice.

@konradsa the hardkernel wiki has all the informationen needed, however I really want to qoute linux-meson.com here: "Not for end users - yet!".

[graysky2]

@mmoll - Can you describe how you're managing your C2's network and bridge? I have tried and failed using both netctl and systemd-networkd (both on Arch ARM and Ubuntu). I do not want to run Ubuntu nor it's native ifup util.

[mmoll]

@graysky2 then I can't help you. I configured it in /etc/network/interfaces.

[mmoll]

(...which results in the same as using brctl, AFAICT)

[graysky2]

@graysky2 then I can't help you. I configured it in /etc/network/interfaces.

I think networkmanager-ifupdown is available for Arch ARM. I will give it a try. Could you post the needed config that I should write out to /etc/network/interfaces to enable a functional bridge? Thanks!

[mmoll]

@graysky2 sure, here my complete config:

NetworkManger coredumps on Arch.

@mmoll - I have ubuntu (ubuntu64-16.04-minimal-odroid-c2-20160815) on the ODROID-C2 now. The network works with the out-of-the-box /etc/network/interfaces.

I installed bridge-utils and slightly modified your /etc/network/interfaces shown below. After a reboot, I have a non-functional network just like under Arch. (I cannot ping anything nor connect to anything)... Hardware???
