WT Play 2: NAND and SD - alpha 10: network disconnecting during playback (Solved)

Quote from jim1985

Just a quick update from my side of things.

For the time being I have had to revert to using Android on my Wetek Play 2. Running Kodi 17 RC 1 under Android works perfectly, no network drop outs whatsoever.
The problem with the network drop outs are absolutely isolated to LibreELEC.

Now whilst using Kodi through Android is a current workaround, I really would prefer to use LibreELEC if this rather serious bug can be resolved at all

same issue here . Kodi under Android no Problem
Libreelec Network Connection not stable (cable)

micha47259 · January 3, 2017 at 9:11 PM

i also check wifi.. and there was no connection problem. so only with a cable connection is the connection problem.. hope someone will find a solution

micha47259 · January 6, 2017 at 5:38 AM

is anyone from the libreelec Team reading here ????
the Problems are still there
yesterday i try to Switch to a cable Connection ... after 5 minutes Network Connection lost ....
Switch back to wlan ... no Problems ...

just linking: LibreELEC

I'm running my own build at the moment, to see if there are any improvements, runs ok so far....lets see.

That sounds interesting Jester. Is there anything different about your build that you know of?

Would it be possible for you to share your build for more of us to test it?

Still no issue, but still testing, and i've made no changes, just a compile from the current github master, Commits · LibreELEC/LibreELEC.tv · GitHub

I've put up a test build here if people want to try, it works fine on mine, but don't blame me if stuff breaks (it shouldnt, but still)

see my post Play 2: network disconnecting (hardware failure ?) - Page 3 - WeTek Community Forum
and add
ethtool -s eth0 speed 100 autoneg off
to /storage/.config/autostart.sh

Thanks, yeah I read that, its my thread however, creates stutter on high-bit rate 4k files, so no solution.

so far no issues with a build from master I compiled

Excellent, I shall try this out when I am home later on this evening.
Is it for SD or NAND? Or will it work on either?

Should work for both, just drop the file in the .update folder of a running LibreELEC and reboot, it will update itself then.

I tried your last image LibreELEC-WeTek_Play_2.aarch64-8.0-devel-20170108131246-r25157-g9e4c5ea.img.gz and network device with 1000 Mbits still shows the frozen behaviour ...

That my workaround (tested it now many many hours) isn't a solution for 4k movies, is clear to me. But maybe it is the right step in the right direction to get rid of this bug. Does the workaround works for you with SD and HD material?

Hmm, too bad, as in that build has an updated kernel, but probably still the same eth0 driver (didnt check)...

For me its still ok...

Grr, spoke too soon, same issue is back.

Just to confirm I have tried this method and it does NOT work for me.

Applied the "fix", rebooted Wetek Play 2, started watching a live SD channel from my TVHeadend server. Somewhere within the region of 20 to 30 minutes later the network controller crashed again.

Back to Android for now again

I'm digging into the eth driver, can anyone confirm the play 2 is using the am_net8218 driver ??

nope, it's stmmac:

Cheers, nothing too obvious except that the driver that is used in the linux-amlogic kernel is very old:

linux-amlogic/stmmac.h at amlogic-3.14.y · LibreELEC/linux-amlogic · GitHub

I'll see if I can whip something up over the weekend, but sounds like a good plan to update these to:
linux/stmmac.h at master · torvalds/linux · GitHub for example.

Given the commits there, some interesting fixes and improvements have been made to the driver....

lrusak chewitt codesnake before I start testing and maybe do a PR, any reason for the outdated driver ? just want to be sure i'm not missing anything
