hi alexwhites,

I'm trying to upgrade the kernel, and in the meantime see if I can backport any patches from the rockchip kernel. But the box, despite the unwatchable screen, still works !? Can you send the output of the dmesg command ?!

JoeEdison although old, with libreelec my box is still usable. And I think with libreelec 11 things could get even better

Hi alexwhites,

after some research, i realized that maybe the problem lies in the rgb <--> yuv conversion.

In practice, the TV communicates, via edid, that this resolution is in a format and therefore the driver behaves accordingly.

In your case it looks like the TV sets itself in one format, but the driver in another and hence the colors busted.

I did not understand if the problem is in the kernel or in the TV, however the legacy driver should force the output in rgb format.

I try to do the same thing and see if it works.

EDIT: try this kernel

testing – Google Drive

Hi alexwhites

according to the edid you have an ACER full hd monitor(or tv), probably with some bugs.

I have enabled a kernel hack for your particular device which prefer a particular frequency. Put this kernel inside the first partition of sdcard (obviously remove the resolution forcing)

testing – Google Drive

and let me known.

Regarding ssv6051 thanks to jock2 there is a driver for mainline but with libreelec I've experienced some problems.

Maybe in the future there will be a better driver, but for now I recommend you to use a usb wifi device. Sorry

Hi all,

I've released an updated build with several stability fixes. See changelog in the first post.

dale, unfortunately NAND is a complicated thing. But I'll do my best

Hi alexwhites

do you have a 4k tv ?!?! green screen usually indicates a resolution not supported by the driver.

try to edit the extlinux / extlinux.conf file present in the fat partition of the sd card by adding

video=HDMI-A-1:1280x720

if works, in a ssh session launch this command

cat /sys/class/drm/card1-HDMI-A-1/edid > /storage/edid

and share the file /storage/edid

thanks

Hi juliomm64,

thanks for the feedback, i have restored my gdrive folder

hi JoeEdison, Lajos

with my latest build, I've fixed some small issue, updated libreelec upstream code, and I've also fixed and enabled suspend to ram with wakeup with remote(that should be better than virtual power off)

edit: virtual power off is not abandoned, just I need more time.

Hi Lajos, thanks for your feedback.

Quote from Lajos

Hello! V88K Plus, The remote control works at startup but if I turn it off it can't be turned on afterwards, it works well in version 9.

I known, I'm working on backport the 'virtual poweroff' driver from legacy kernel.

Libreelec 10

FEATURES

- kodi matrix 19.5

- mainline kernel 5.10.186

- mainline opensource gpu driver

- legacy u-boot

- ddr3 frequency scaling

- boot from SD

- boot from EMMC (thanks to jock2 for testing)

- boot from NAND

- ir receiver (it works, but if your remote is not recognized, follow this guide https://wiki.libreelec.tv/configuration/ir-remotes and share results)

- wifi/bluetooth only if there is a mainline driver (I'll do my best for others, but is more safe eventually to buy an external adapter)

- hardware accelerated video decoding (mpeg2/h264/hvec/vp9). only FullHD tested, because I don't own a 4k tv.

- virtualpoweroff with wakeup with remote

- analog audio

DOWNLOADS

- older builds (< september 2022): https://drive.google.com/drive/folders/…0IoQVjQdlMaafNx

- builds: https://ilmich.libreelec.tv/libreelec-10/

- source: https://github.com/ilmich/LibreELEC.tv/tree/libreelec-10.0

INSTALLATION

- for boot from SD see https://wiki.libreelec.tv/installation/create-media

MANUAL UPDATE

Copy (via ssh,samba, etc etc) the desired build into folder

/storage/.update

and reboot device.

INITIAL SETUP

To allow booting in most cases, the image uses a generic device tree. This device tree doesn't have support for ddr3 ram, doesn't turn on any LEDs, etc etc.

However, it's possible to change the device tree by choosing from the supported devices list with rk322x-dtb-switch.sh command.

rkelec:~ # rk322x-dtb-switch.sh
usage: /usr/bin/rk322x-dtb-switch.sh [list|switch|help]


show                      show current device tree
list                      show available device trees
switch [device tree]      switch to a device tree
help                      show this help

Device tree rk3229-box-v88mars founded
Are you sure(y/n)?y
Mounting flash rw
Switching dtb
Mounting flash ro
Switching is ok, now you need to reboot!!

SUPPORTED DEVICES

The following table shows the supported devices (with device trees).

Device trees with the suffix -ovclk contain some changes to slightly overclock cpu/ram. Overclocks are tested, but may make your board unstable. So use them at your own risk.

KNOWN ISSUES

- gui may not be smooth (it also depends a lot on the skin used, like legacy builds)

- for drm contents, resolutions >= 720p are not guaranteed. This is because decoding is software and the cpu/gpu may not make it

- analogic video not works (and maybe never will)

- let me known

SUGGESTIONS

- if you have problems with pvr clients during channel switch, set a delay of around 200ms in order to let kodi and gpu release resources correctly.

- stay at 720p and let kodi switch resolution when play something

- without your logs, I can't try to fix anything

hi bluetako , my tips is for libreelec 9.2. On mainline kernel works different.

Try my unofficial build of libreelec 10 with kernel 5.10.x

Hi,

thanks to the experience gained with my builds of libreelec 9.2.x and the work of the community (rockchip and more), I'm sharing my unofficial build of libreelec for boxes with soc rockchip 322x.

** BIG FAT WARNING **

hi bluetako

on legacy rockchip kernel there is a module called rfkill that is responsible for the wifi wakeup and probe.

So in your dtb leave the 'wlan-platdata' in the WiFi node (this autoload rfkill) and change the wifi chip type according to your chip (for example rtl8723as).

If works let me known, because I'm not working anymore on this build, but I know that for some users LE 9.2 is better. So maybe I'll try to add also this device

cheers

I don't know if officially there are devices with mali 4xx, but I solved it by applying this patch to mesa 21.0.3.

lima: limit number of draws per job (!10121) · Merge requests · Mesa / mesa

Otherwise we may hit tile heap size limit if an app issues too many draws per job. Fixes

gitlab.freedesktop.org

this patch is now also upstream.

Quote from bluetako

Looks like it's bcm4329.

Code

h96miniv8:/ # cat /sys/firmware/devicetree/base/dwmmc@30010000/wifi@1/compatible
brcm,bcm4329-fmac

EDIT: this seems to be wrong - it's coming straight from the dts. Is it possible to get the wifi card model from the sysfs, or do I have to open up the box?

unfortunately yes, you have to open the box and read the label of the wifi chip, or if you have another working SO (like Android), retrieve the information in another way.

ilovefly if you have a spare sd card why not but keep in mind that often info about ram can be faked on Android (on libreelec instead it's the real one)

I updated mesa to the latest version and saw that there are several improvements and bugfixes for lima driver.

the problem seems to have disappeared

cheers

Hi everyone,

I'm working on an unofficial libreelec 10 build for soc rockchip 322x (not released yet).

It's a mix of the work done by knaerzche and some patches taken by armbian ( fabiobassa and jock2)

It works pretty well but I only have one issue that I don't know if I have solved it well.

Starting streams decoded via software (netflix addons and similar) after about 6 minutes there is a kodi crash due to an EGL_BAD_ALLOC error (log attached).

I tried with different cma memory sizes (from 64MB to 512MB) and also lower resolutions, but the only solution was to disable the dmabuf management in the kernel.

I suspect a memory leak but I'm not sure. Can anyone help me!?

Cheers

Michele

bluetako wich builds?! mainline or legacy?!

Can you please share more info of WiFi chip?! (brand and model)

cheers
