New kernel

Unread postby jason_a69 » Fri Aug 10, 2018 7:13 pm

Hi there,

According to this
https://wiki.odroid.com/odroid-c2/softw ... ing_kernel
I can build a kernel version 3.14 from source.

To be honest, this is not much good, it is too old. I have a DVB-T2 device that does not work properly (https://linuxtv.org/wiki/index.php/File ... a_2017.jpg) because the kernel is so out of date. I have tried to install media_build today but it is an exercise in frustration. I reference this thread viewtopic.php?f=136&t=20302 but it does not work.

Do you have any plans to bring the kernel up to date? 3.16 was released in 2014.

Thanks

Jason

You can build a modern kernel with Armbian tools. It's in a pretty good state but ofc there are still some issues. https://github.com/armbian/build

Thanks for that but I really think hardkernel should be building this and releasing it with their OS.

Long story short.

Board makers main advantages and focus are in a graphics areas where they tend to provide all sorts of stuff: GLES, KODI, Chromium, etc. and for that, you need to stay with the legacy kernels/old technology. For server case scenarios, which you are interested in, you can easily grab a modern kernel (which exist with Armbian for years). Main community development for (sponsored by) Amlogic powered hardware starts here: http://linux-meson.com/doku.php We are involved in this process with C2 and a few similar boards: https://forum.armbian.com/forum/16-amlogic-s905x Most of the TV Boxes out there are also powered by Amlogic chips, similar to C2. We cover those as well, but unofficially: https://forum.armbian.com/forum/24-tv-boxes

We provide the same kernel as Hardkernel, modern 4.17.y kernel, development kernel 4.18.y, fully optimized and clean Debian or Ubuntu builds. All with powerful build/dev tools. Board maker minimal OS or SDK is/will not be even close to this level. "Better than original": https://forum.armbian.com/topic/7787-wh ... bian-linux

And you need to ask why we don't provide Ubuntu 18.04 images (we do but with a label "beta") since there are still too many bugs, Hardkernel does. Because you/users demand it.

This is good news. I spent the weekend trying to build a kernel from source with these drivers built in https://git.linuxtv.org/media_build.git/ , unfortunately I did not have much luck.

Looks like I will not have to wait too long.

:oops: I notice after I post this. I don't pay attention to multimedia stuff and I completely missed out that topic. Thanks!

Good news, yes, but it might take months to get to the mainline kernel. I am not sure you need this kernel feature for serving DVB content. This is for playing it on the device.

Me to. But. For that, you will need to wait much longer. One is to develop some support another is to make it stable :)

I've been using the Odroid as a dual DVB-T tuner server with Tvheadend with the stock kernel for a year or so now (both with 16.04 and now 18.04), and playing HW accelerated video via Kodi. USB DVB-T Tuners based on RTL2832U the chipset are plug 'n' play on our old kernel, and available for $10usd or less. They aren't HD though, but if you can tolerate SD content they are cheap and easy. They also aren't very sensitive, so you'll need a decent aerial.

Hope that's useful. :)

If I recall I was having problems getting the HD tuner to work, thanks for the info though.

Dont just combine the Realtek RTL2832U with the capabilities of what can be received. The Realtek RTL2832U is just a SDR chip. What you are talking about is the capability of what additional chipset is beeing combined with the RTL2832U. For DVB-T (the SD one, not the recent DVB-T2 one) in most recent usb devices with just DVB-T capabilties and RTL2832U an (now discontinued) Rafael Micro R820T or R820T2 are beeing build in. Just take a device with R828D build in and you are done. Then you have a Realtek RTL2832U with DVB-T2 and DVB-C capabilities. If you want DVB-S/S2 just take one with R848. http://www.rafaelmicro.com/product/list/66

Back to topic:
I would love to see official images by Hardkernel with recent mainline kernel and grapics working. Otherwise the odroid devices cant be used any more when the kernel support drops in situations where you want some security and not make it possible for anyone in the same network to be able to take over control of the whole system. And such security related situations are probably always valid. Otherwise some kids can play around into making odroids in the same network unanvailable by letting a script run that use the known CVE security issues to get into the device and then rm -rf / the whole system.

armbian, could you please make such a testing image that have graphical output and some desktop?

It exists for a while - very 1st download option, Debian Stretch based image with a desktop - https://www.armbian.com/odroid-c2

Current kernel version is 4.18.8 but there will soon be upgrade to 4.19.y (which is LTS), video acceleration state is unknown to me, but it is developing ...

Oh, sorry, i forgot we are here in the C2 section. I had the C0/C1/C1+ in mind. I was willing to test out the opensource Lima GPU driver on Mali 450. C1 and C2 have the Mali 450. I asked now here why there is for the C2 a desktop mainline kernel version but not for the C0/C1/C1+ : viewtopic.php?f=114&t=26992
