And after you've invested that money another chinese manufacturer comes a long and builds a similar device for half the price.

The verb 'building' is a bit misleading here, 'selling' would be a better fit. If you manufacture cheap electronics assembly and parts are the big cost factor, but don't forget about:

• designing the thing, NRE
• QA testing during production
• Warranty/RMA

And as you mentioned above, software support.

And yes, Penang is a nice place, my wife has to travel there from time to time to troubleshoot things at their factory there. I wouldn't mind some roti canai right now

Quote from Jefken

Please, can You tell me the terminal command to update your sources tree?
Is "git fetch origin" enough?

'git fetch' will only download the changes, but not update your source tree, to do that, use 'git pull', which will do a 'git fetch' automatically.

Quote from endian

Hmm.. What level of support is missing?

Are you saying that ARM haven't published MALI-T820 interfaces, or that Amlogic haven't released any devkit for the S912?

Last time I checked the userspace libraries are missing from the amlogic site. It could be that the binaries ARM ltd publishes will "Just Work(TM)", but afaik no one has tried that yet.

Quote from Bambonik

Please kszaq build something for S912. I believe you can easily do that.

No, he can't. The needed mali userspace hasn't been published yet. The s905 and s905x are similar enough to support in a single build, the s912 is too different to do that.
Which also means that anyone can copy the S905 subdir in LE to S912 and start hacking without having to coordinate with anyone. Provided the mali blob shows up soon.

With the image from 2016-10-03-devel and this dtb gxbb_p200_2G_beelink_minimxIII.dtb on a Beelink mx III CEC doesn't work anymore:

The topology is mxIII -> Onkyo receiver -> Samsung TV. It was previously working quite well, but after upgrading it by putting the img.gz in ~/.update CEC stopped working.

This seems to be a side effect of running from eMMC, running from uSD doesn't show this problem. And better, running from uSD will use eMMC as storage, so all my settings and libraries are being picked up.

Using 2016-10-03-devel on an M8S II boot from USB works, upgrading eMMC worked as well. 4k h264 playback also works!

Userspace libraries for the MALI GPU would be a nice start, the kernel drop from amlogic seems to have most other things already included for S912.

Quote from kszaq

ermethic We use the same CEC implementation in our builds: Amlogic driver with support for libCEC from Raybuntu.

Speaking of CEC, the displayed name is hardcoded in the .dts file to 'Mbox', would you accept a patch to hardcode it to something like 'Kodi'? A better way would be to have the LE buildsystem change it, but I haven't figured out how to do that yet

Multichannel PCM works on my mxIII:

Quote from chewitt

Do you have the nouveau changes in a git repo anywhere?

Yes, but it's not running LE, so pointing you to GitHub - koenkooi/meta-kodi: The official OpenEmbedded/Yocto Project layer for Kodi would not help much. It's linux 4.7.1 + mesa 12.0.1 + xorg 1.18.4 + xf86-video-nouveau from git and the matching firmwares. I disabled the "prefer vdpau mixer" in kodi as well. From a quick look at the LE git tree it's only missing a package.mk for the xorg driver and the firmware.

FWIW, nouveau works well enough on my revo ION1 box, most issues crop up with live tv, progressive scan content works without problems.

After Power Off then Power On some times is hungs and display
*** Error in mount flash: mount common: Could not mount /dev/mmcblk0p1 ***
and after disconecti power, wait 10 sec, conect power some time Boot normaly
!!!

I get that as well when using the uSD card, that problem went away after installing it to eMMC, which I realize isn't an option for everyone.

Quote from wkchick

Just read this article: Tanix TX5 Pro TV Box Review – Part 2: Modding and Testing, under section 4K it said: 'The Amlogic S905X does not supports h.264 60 fps above 1080p'.

I also don't get the logic of 4K h.264, which is supported by S905 but not by S905X while this format is now more and more popular in Asia. Not sure about what would happen with S912!

Judging from the kernel sources s912 ('gxm') is an s905x ('gxl') with a different MALI and an extra a53 cluster.

You don't watch Jellyfish every day in 120Mbps, do you? 100Mbps may be not enough for UHD BluRay but it's sufficient for UHD DVB-S which are ~30Mbps.

I did watch it each day every day this past week

This will change for the next build.

koenkooi Can you try if rootwait in CMDLINE with my standard options helps booting?

I neglected to mention earlier: 4k playback issues on an 1080p TV are still the same: big buck bunny 2160p30 switches to 1080p60, black screen, sintel 2160p24 switches to 1080p24, black screen.
FWIW I don't get the logic behind using a 100Mbit PHY for a 4k box, it is *just* enough for jellyfish 90mbit. I realize on s905x you get it for free, but still...

It boots and works after merging in your changes, the diff between your build and mine: git diff

Going to add console=tty0 to the next build and see what happens. For the adventurous people among us, the .3 build in the same dir as the diff is the one I'm testing.

Looking at the diff your TV box seems to have 100Mbit ethernet, the other devicetrees all specify a gbit phy connection using rgmii.
