I confirm that now I am able to boot my Pine H64 when it's plug to my AVR. That was not the case before.
Great! Thanks for confirmation.
Is it possible to merge that fix with the test image for audio passthrough ?
Of course it is 
It's just that first I would like to get these fixes in LE master and to kernel. I'm also curious if this will help PT. I'll try to do that soon (some patches need to be rebased), but I can't say when exactly.
is it technically feasible to not just send the SOC to sleep, but in fact shutdown Linux and power off the ARM cores and use the ARISC core to power them on via remote or button and perform a proper boot from scratch?
Of course, that is already implemented, it just acts up on Beelink X2. It works reliable for me on OrangePi Plus2E and BananaPi M2+ (speaking about H3 boards).
BeelinkGS1 Just by sheer luck I manage to find few H6 HDMI related bugs and fix them. Can you please test update mentioned in this post? RE: Nightly images for A64, H3, H5, H6 and R40 boards
Main reason for slow shutdown is usage of python-dbus, which is phased out (doesn't really work with python3). It should be out when LE10 is released. This will shorten shutdown time for about 20 seconds, maybe more. Slow startup is due to service which waits on network. Most of the time it timeouts, even if network is up already. This is caused by recent service rework. I didn't look into the reason why it almost always fail on AW boards.
MoToR Timpanogos Slim kursantkvi I finally manage to find H6 HDMI bug (actually two), which prevented proper working. Please test following H6 update: LibreELEC-H6.arm-9.80-devel-20210202235002-b20ba58.tar

With above image, even 4K @ 60 Hz works for me.
lumpi power button just toggles power menu when in Kodi. When box is suspended or shutdown (only ARM cores are suspended/shutdown, ARISC co-processor is running), you should be able to resume/power on the box, either with power button on the box or via original remote. So clearly there is something in that co-processor FW which doesn't play nicely. I'll take a look, but no promises when. Above fix for H6 give me opportunity to work on 10-bit modes 
Too much fun stuff to do, too little time
I'm fully aware that this bug still exists, but it's impossible to work on it because I don't experience such symptoms on my TV.
if you execute "systemctl restart kodi", does it work? Also, do you have plain Kodi or do you have any addons, especially PVR ones? There were some suspend/resume issues with Kodi discovered and fixed. Kodi was just updated today in LE, so please re-try with tomorrow image. Suspend/resume is complex, every driver must work correctly...
Original, NEC 0x8051
lumpi What is your test case exactly? If you boot up Kodi normally and then select through power menu suspend or shut down, you should be able to revive box either with power button press on the box or on the remote.
Before I updated my X2 today, it had image from 2019. Update went through without any problem.
Passthrough is really not a priority... It will probably not be present in LE10.
Looking forward to crust coming to my beelink x2 sometimes in the future.
Support for that just landed and it will be in tomorrow nightly image. However, it's unreliable on my Beelink X2, but it works just fine on other boards. Please test it on your X2. I have problematic version of that box (hard to boot from SD card), so chances are that it will work reliably on non-problematic.
Yes, I'm referring to that one. It contains update file (albeit old one), which can be used to update (or, in this case, downgrade with different features). Just put it in .update folder and reboot (you have guides for that).
img.gz files are always board specific, while updates can also be universal. That's why I release only universal updates for testing new features whenever possible, I have to intention to upload 10 almost same images.
you should really check pinned threads...
Read main topic - it's unsupported and it will remain so.
oh, forgot to ask, is there anyone interested in TV out (composite, CVBS) on H3 or H5? I have test image...
MoToR Timpanogos Slim kursantkvi Can you please test this H6 update? LibreELEC-H6.arm-9.80-devel-20210128183834-7d0199b.tar

To all,
recent updates:
1. Suspend/resume and power on via remote and power button should work reasonably well on most H6 and A64 boards. H5 was not yet tested and H3 is work in progress. On TV boxes remote IR wake up/power on key is set to the same scancode as remote which come with the box (currently only Tanix TX6). On all other boards, wake up IR key is configured as RC6 MCE remote power button. This unfortunately can't be configured at runtime yet.
2. Installation command was added - install2emmc - it creates clean installation on emmc from currently running image (no download is needed). If you want to transfer settings, backup and restore functionality must be used.
3. Support for DT overlays - if you want to modify DT, this should be used. Just drop dtbo file to overlays folder on FAT partition and add a line in extlinux.conf. For example, activation of IR on PineA64 would be FDTOVERLAYS /overlays/sun50i-a64-ir.dtbo. You can specify multiple overlay files, if you want. Overlays are preserved over updates. Note - if there is an issue with applying overlay (wrong file path, incompatible overlay, etc.) board won't boot. In such case fix the issue or just remove it from the overlay list and it will boot again (annoying for emmc installations).
Not sure if it possible to override that.
