I am trying to map some of your github commits to change log. Can you check If I did it correctly please ? Format:
- changelog_entry
(commit_message - commit_url)

You are correct in all cases. Additionally reverting sound patches for click/pop fix requires kernel commits: Commits · kszaq/linux-amlogic-le · GitHub

tvheadend client playback still jerky as in .008 and .009. Back to .007 for me.

The patches I use for .010 have been in development build for 2 weeks IIRC and no one complained. Unfortunately I don't have a TVHeadend server nor any other PVR service to test. So far everyone else's results were very good and current a/v sync patch works best from all from what I can tell.

I am trying to build linux from amlogic official buildroot and seem to have trouble with soundcard.
Now I remember coming upon your post saying that s905x has "special" soundcard and needed to
be disabled in order for hdmi to work. Could you please provide any hint or direction on how I might
proceed to achieve same result on linux built from latest amlogic sources.

I have never built from Amlogic buildroot but I will try to help... S905X does indeed have a sound codec built in and it's T9015 - you need to enable it in kernel config to work. To make sound over HDMI work you should have this codec enabled or modify device tree to use dummy codec but the latter won't give you sound over analog. That said I think you should start with meson64_defconfig.

I am a noob here and having a problem - I followed the instructions but I have a problem in that the device just hangs before anything happens.

I used Rufus and formatted a USB Stick 4GB with the image and then copied the dtb.img to the file (after renaming)

Try the latest development build from my previous post. When making a "fresh" install - writing image in Rufus - try not replacing device tree first.

The DACs on the USB-receivers XMOS 8U6C5 - Periodic crackling, Strong distortion.

Try this build: LibreELEC-S905.aarch64-7.0-devel-20161212221553-r23560-g512a087.img.gz

This has the only non-upstream commit I can think of reverted that can cause your issue: dwc_otg: do not queue transactions if we do not have enough time in a… · kszaq/linux-amlogic-le@bbef74b · GitHub
If this doesn't work, I'm afraid I can't help any further.

Quote from gamicoulas

Out of curiosity, looking at the lists of dtb files of these two versions, the sizes don't match! How come the device trees are the same?
I ask because I too have booting problems (stuck at Beelink logo) with the .010 version...

OK, I must admin that there is a small change:

• in .009 GPU is forced to use the highest clock available all the time
• in .010 GPU uses standard clock but driver switches it to Turbo mode instead

The change is reflected by these 2 commits:
gpu-aml: set Mali to turbo mode by default · kszaq/LibreELEC.tv@aeec7ad · GitHub
Revert "arch/arm64/boot/dts/amlogic: Set Mali-450 minimum clock, defa… · kszaq/linux-amlogic-le@10a15b8 · GitHub

This cannot prevent booting because these settings are applied when Mali driver is loaded = at LE splash screen. Try the latest development build.

A first post-010 development build to test, changes:

• Revert projects/S905: compile USB drivers as module · kszaq/LibreELEC.tv@1527eba · GitHub
• Revert projects/S905: use 4K scaling patches from LE master · kszaq/LibreELEC.tv@71abe4c · GitHub
• Enable CPU Idle driver
• Enable SYSCON for missing symbol needed by media_build
• Revert Amlogic "improvements" to serial driver: Revert "PD#118626: tty: merge tty changes from 4.3" · Extro-development/linux-amlogic@6bb1506 · GitHub

Download from LibreELEC-S905.aarch64-7.0-devel-20161212161011-r23559-gd4fc4f6.img.gz

Please focus on (re)booting issues. Thanks in advance for testing.

Alright, I will check this out later on. Right now 7zip did not show the files kernel.img or SYSTEM in the img.gz.

You need to open img.gz, then .img inside it and finally 0.fat. Then you will see needed files. You can keep opening in 7zip, no need to unpack.

Quote from minimoe

I installed the 32-bit 7.0.3.10 version. Is it safe to downgrade to 7.0.2.009 using this method?

Yes, as long as you reinstall binary addons.

Quote from sYCO

Yes, I know, but did you not have a very first 009 release with
a different device tree file BEFORE Nov, 6th? But as I said, I
might be wrong.

Device trees were the same.

Quote from sYCO

Is not there a simple backup way to copy the complete SD card,
make the update and if it does not work, restore the previous
thing (like on Android with TWRP).

There is a very simple way to downgrade if you're using SD card: if you're using Windows you can use 7Zip to unpack .img.gz file down to first SD card partition content. Then simply replace kernel.img and SYSTEM on SD card with the ones that you unpacked.

Kernel driver has been available for some time at Index of /download/ARM/gpu

Amlogic doesn't have fbdev libs for S912, at least none that they can share. That's all I know.

Quote from sYCO

As far as I remember there was a device tree file for the very
first 009 version, that got pulled, before Nov, 6th ... and this
one worked.

This is not true. All .009 and .010 device trees are the same.

The latest build as of now is 7.0.3.010.

Quote from sYCO

For the S905 chip I think you might check
the DTB file from November, 6th. You
changed something there and since then
the boot problems occur (on several boxes).

November 6th is .009 release date and all changes in device trees come from Amlogic kernel updates.

kostaman Yes. It should work OOB in 7.0.3.010.

Please don't. I'm in touch with Amlogic regarding fbdev libraries for S912. No ETA though.

Edit 2 Some Rpi users may had same issue http://forum.kodi.tv/showthread.php?tid=...pid2374902

Fixed with patch http://www.horus.com/~hias/tmp/libreelec...nput.patch

An earlier version of this patch is included in LE 7.0: LibreELEC.tv/lirc-0.9.0-026-uinput_key_fix.patch at libreelec-7.0 · kszaq/LibreELEC.tv · GitHub

karolgarlicki Witaj na forum i dzięki za szczegółowy raport w pierwszym Twoim poście!

I will try to reproduce the yellow tint issue with my TV set. Meanwhile can you try if forcing RGB colorspace solves the issue for you? You can do this by executing echo 1 > /sys/class/amhdmitx/amhdmitx0/output_rgb. This command can be added to autostart.sh if it improves things for you.

About installing to internal, I have seen some boxes that don't allow replacing device tree outside recovery. You might want to try to execute fw_setenv upgrade_step 2 before running installtointernal.

Quote from bluefuzz

Should this be working for audio over a USB dac? Because clicks and pops are much worse on this build for me over USB ...

No, the fix is only for internal audio codec. USB sound cards is another story that is also planned to be looked into after more important issues are resolved.

Lots of new post and I'm a bit lost which ones I need to answer...

I will be looking into (re)booting issue shortly. Weekend was family time, now it's time for a bit of hacking.

The bad news is that between .008 and .009 there was a big kernel bump which I don't want to revert. I hope that (re)booting can be solved with a proper set of kernel config options. Or a patch that will show up from Amlogic.

Does 7.0.3.010 support WiFi dongles with this chipset : RTL8811AU

If not, can you direct me to a list of supported wifi dongles?

Cheers

There is no list of supported dongles. You can see which additional (Realtek) drivers are compiled in: LibreELEC.tv/options at libreelec-7.0 · kszaq/LibreELEC.tv · GitHub

Quote from x-kent

I have built your branch from source and found out that there are some differences between the 7.0.3.010 image you provided and what comes out after building 7.0.3.010 from your git.
The binary files differ for some reason(although both should be built using the LE toolchain so theoretically should be the same) but there are more than just binary files.

Binary files will differ because the compiler signature is different depending on your host OS. What OS do you compile with? I build on CentOS and the "most supported" is Ubuntu. I hope you don't use root account to compile?

smoothquark CEC issue with Krypton has been solved but I have not published a fixed build yet. I'm now working on getting media_build drivers to work and I'll post a build when it's done. Meanwhile you can get a fixed libcec patch from LibreELEC.tv/libcec-00-amlogic-support.patch at master · LibreELEC/LibreELEC.tv · GitHub

"Go Thumb" patch makes the code compile by default in Thumb mode which makes it a bit smaller and maybe a bit faster. I know that it doesn't work for the RPi but I don't compile for the Pi.

felixob Changes that improved audio had to be reverted because clicks and pops. I think Kwiboo is still working on improving audio for S905 devices: sound/soc/aml/m8: work-in-progress by Kwiboo · Pull Request #23 · LibreELEC/linux-amlogic · GitHub

When the PR is considered final and I am able to confirm that there are no issues with clicks/pops etc., I will merge the changes back.

Is anyone with booting issues able to grab me a log over serial console?
