hv00 sorry for late reply. I have suspicion that OPi PC variants changed and don't have 32 kHz crystal anymore. Can you check if you have v1.2 version? Can you provide detailed photo of both sides with good enough quality to read out markings?

is H265 (HEVC) hardware decoding still supported for H3. im running LE11 and im having problems with playing FHD HEVC content due to it being software decoded(the output is choppy).

It works fine on LE12 nigthly. It doesn't support 10-bit HEVC though. Can you check if that's the case?

eraldin96 I just tested LE11.0.6 on BPi-M2U and HDMI output works fine. Can you give more details?

Before Libreelec 12 it always started up in 1080p but since libreelec 12 it starts in 2 of the 3 times on 1024x720. I have to reboot a few times to get it in 1080p.

This sounds like there is an issue by enabling DDC lines to read EDID. Not sure how this can be random. I guess I'll need to test it for myself, but not sure when.

I just added video=1920x1080@60 to the append line in extlinux.conf. I hope this will fix it.

That will help with video resolution, but you'll most likely lose HDMI audio.

In case this is the wrong way to do it, what's the correct way?

To fix kernel/DT issue

Quote from roel

getedid doesn't seem included in Libreelec for Allwinner.

no, but you can find edid blob in sysfs and use edid-decode to get readable text. In any case, 1024x768 resolution is indicative to failed EDID read.

Sorry for late response. There is nothing relevant that changed for analog audio, except kernel. Can you test LE13 nightly images?

Try to install latest LE12 nightly. There were some fixes about video playback.

If anyone is interested, I can also post WIP images where video decoding is re-done and TX6 is capable of smooth 4k@60 HEVC playback.

I'm not even familiar with the TSC driver. Where is it?

Enable ssh, connect to it and run install2emmc. WARNING: it will wipe out Android without backup!

LE supports only wifi chips which are natively supported by mainline kernel. You most likely got some XR819 or other random Chinese wifi, which is not supported.

sorry for late response. This was fixed last month and you can use nightly images

Most of the time, AW boxes come without root password, but there is this very old trick: https://olimex.wordpress.com/2016/05/10/how…d-linux-kernel/

In any case, I suggest #linux-sunxi IRC channel on oftc server for further help. This is not general dev forum.

Provide a debug log, there is just too many questions.

one question, 12.0 release uploaded on wesnesday has ethernet issue fixed or will you launch new one?.

No, official LE12 release doesn't have this fix, but it will be in next point release. However, image that I uploaded is basically LE12 source + fix, so you can use it till point release.

Great! I'm glad it works. I'll prepare PR next week. I guess you can use this image for foreseeable future.

Making proper board support means creating device tree file and proper U-Boot configuration. This gives you board specific binaries which can be also used for FEL booting. In the H3/H2+ era, this was done by first dumping firmware from the board and extracting script.bin, which is then converted to human readable named script.fex. This file contains all board specific configuration, which is used for creating device tree file and U-Boot config. In any case, you have to first obtain access to existing system, so you can dump it. Since UART doesn't work, I don't have idea how to do that.

jordixPI3 I updated test image here: http://jernej.libreelec.tv/test/opi3-lts/ Please test.

I tweaked RX delay on PHY and ethernet controller to be in sync with schematic and vendor kernel. It adds 450 ps delay in total, which may not seem much, but that's a lot when talking about gigabit ethernet. Additionally, I slightly tweaked reset timings, which will ensure PHY is properly powered up.

In any case, my quick test showed that it works.

FYI, I finally found datasheet for ethernet PHY, so I can experiment with more sensible settings. Maybe I can figure out more stable values.

Nope, FEL doesn't produce serial output on its own. But you can run binary which it can produce some.

You can only access whatever is memory mapped, so RAM and peripherals. In any case, I would suggest to run "ver" first to see if it works.
