^ the second and third lines are a single line (the forum wraps it). The file needs to be edited with something that respects Linux file endings. In the past Notepad.exe would mangle the file with Windows line endings and boot would break, so you'd need to use a text editor like Notepad++ to avoid the problem. I'm not sure if newer Windows OS learned not to do that, or if that's your issue..

NB: The video= content only sets the initial DRM connector state. Kodi can then mode switch to something else once running. Kodi only outputs progressive, never interlaced; hence you will never see interlaced modes listed/available for selection.

Did I miss something or is the TVH PVR Client vanished from nightly Generic builds?

This disagrees with you: https://addons.libreelec.tv/12.80.4/Generic/x86_64/pvr.hts/

Have you tried force-refreshing the LE repo?

Thanks for confirming and sharing the log. I've sent the wifi firmware patch upstream: https://patchwork.kernel.org/project/linux-…[email protected]/

For other Q's:

1. If using Composite output the DRM connector cannot auto-detect the presence of a display (or the display type) and you probably need to force ouput, e.g. for NTSC add video=Composite-1:720x480@60ie and for PAL add video=Composite-1:720x576@50ie to boot params in uEnv.ini on the SD card. Note that the default Estuary skin in Kodi is designed for a minimum 720p screen so when used with something smaller navigation can be challenging.

2. LE does not support boot/run from eMMC with Android boxes: https://wiki.libreelec.tv/hardware/amlogic#installtointernal

3. No, because the box implements rmii (internal-phy) not rgmii (external-phy) so in the upstream kernel p201 is the sole correct dtb to use. I've no idea why the upstream and downstream numbering for GXBB development boards is different, but it is.

NB: ethmactool "errors" are harmless and can be ignored, it's simply a boot-time script that ensures the Ethernet MAC is unique

If you have an older nVidia GPU (and didn't read the release notes) you can 'update' back to 12.0.2 again.

It looks like upstream linux-firmware moved the mt7601u.bin files to the mediatek subdirectory in https://git.kernel.org/pub/scm/linux/…35d3cf5bb8a8fcb so a patch is needed to check the new location (and the old one, to preserve compatibility).

I've written/added that patch now: https://github.com/chewitt/linux/…0fa9514c1bccaed so go download the AMLGX image from my test share again and the MT7601u chip should now find the firmware. NB: Only test the AMLGX image with the p201 dtb - anything else is wasted effort and noise.

Please see if an LE13 nightly or image from my test share works better? https://chewitt.libreelec.tv/testing

I don't see anything that looks obviously wrong. The channel is opened and you can see ffmpeg parsing content. Two audio streams are found; one is mpeg2audio which I'd guess is stereo, and one is ac3 which I'd guess has 5.1 audio, which is selected alongside the H264 video content.

Disabling VAAPI changes the process flow inside Kodi, although I'd have to go look at code to understand more. I'm wondering what differences might exist/show in the logs as a first step. Please share some additional debug logs (separate logs/pastes if possible, as these are easier to search).

• Show an SD channel with VAAPI disabled
• Show an HD channel being opened

NB: LE did bump the Tvheadend version last week https://github.com/LibreELEC/LibreELEC.tv/pull/10719 but the list of changes in the update are not particularly interesting (compile fixes, translation updates, etc.). There are also ffmpeg changes to improve the transcoding capabilities (mentions of VAAPI here, but this is encoding not decoding) so I'm not immediately seeing a connection to the problem reported.

The feature was added to the addon in the last two days. You just happen to have needed it as it was merged/built/published.

Remove all HDMI settings from config.txt. HDMI settings belong to cmdline.txt now.

Note that 'kernel param' settings in cmdline.txt are completely different from old-style config.txt settings. If you put the old-style settings in the wrong file the board probably doesn't boot.

I don't see the errors reading firmware/version that you do when running flirc_util, e.g.

ROCK5B:~ # flirc_util

I'd suggest contacting flirc support as they know their hardware better than we do.

The upstream kernel p200 dtb is for devices using external-phy (rgmii) with Gbit Ethernet and the chip on reg=3 of the MDIO bus.

The upstream kernel p201 dtb is for devices using internal-phy (rmii) with 10/100 Ethernet.

The downstream kernel gxbb_p200_1G_100M_RealtekWiFi file uses rmii so p201 upstream is the correct one to use.

In the upstream kernel both p200 and p201 have identical SDIO (WiFi) configuration inherited from the p20x.dtsi. This is set to probe SDIO reg=1 and although it is technically possible to have other SDIO reg assigments on the bus, I have never seen any Amlogic device with any SDIO module use anything other that reg=1, so the p201 dtb should result in SDIO probing and loading of the WiFi driver in the image. I'm not seeing any SDIO probing so you either share a log from the CE image to prove something exists, or we believe the upstream kernel logs that show a MediaTek MT7601U chip connected to the USB bus. Assuming this is not an external USB dongle; the chip is internally wired. If true it will be the first time I see that specific chip used in an Amlogic box, but it's a cost-engineered (cheap) internal-phy box with 10/100 Ethernet so using a cheap USB chipset internally is completely plausible.

The latest RK356X, RK3576, and RK3588 images in my test share have a fix for broken multi-channel audio (missing channels and speaker placement issues). Enjoy

No idea .. perhaps see if the LE13 images in https://chewitt.libreelec.tv/testing are any different?

It won't be unless you install the "flirc_util" add-on from the LE repo and then logout/login over SSH.

There's been recent activity here: https://github.com/LibreELEC/LibreELEC.tv/pull/10592 .. but it reads like some further work and testing is required before things are mergeable.

I'm using a BT remote with an RPi5 on LE13 nightlies for years so I don't think there's a general issue with Bluez. The only issue I have is a few unmapped keys, but that's laziness on my part. I keep telling myself it's a "rainy day" task to update the hwdb file, but as it only rains twice a year (briefly) here it never happens

Connect the RPi directly to the projector and I'll take an educated guess that the 1/4 screen issues go away. Then if you add spliters and adapters etc. inline the issues reappear and you'll know the self-inflicted cause.

I'm not expert on config.txt options but I doubt the HDMI tweaks you added there do anything. Almost all the old firmware tweaks were obsoleted when RPi switched over to the upstream kernel display pipeline (some time ago). Many of the old tweaks have kernel DRM equivalents though.

Quote from dvamg

these should be different boards/dtbs for different boards?

LE is not CE so in some scenarios CE 'fixes' result in something that works better on some piece of hardware. In other scenarios the absence of those 'fixes' results in LE working better. Roll dice
