Hi digicroxx

the problem, which also emerged in the armbian forum, is that apparently this board only works with the 1.0.1 trust (libreelec mounts 1.1.0). I'm trying to figure out what I can do. Can you please share a link with a downloadable firmware of your box?

And would you be so kind to also suggest me some links to learn more technical details about the boot process of these SoC? (I would like to become more knowledgeable in this field...)

I recently made the famous discovery of hot water :). In practice, if the RAM runs slowly, the CPU has more difficulty managing the system. So while I previously thought that the CPU was too old to decode a 720 video via software, I realized that in reality by increasing the DDR3 frequency it does it just fine.

So in the dtb I passed to you, I raised the frequency of the ddr3 clock. I don't think this affects DVB decoding (I tried local video without any problems). I'll try to take a look at it because I also have the same problem as you, but I'm thinking more of an update to the addon than anything else. You can try either with older versions of tvheadend/pvr.hts or using iptvsimple client (tvheadend also exposes m3u8 lists)

Another detail I noticed is that in Netflix, if I want to resume a video that I previously switched from VP9 to H264, the TV box restarts. However, sticking to H264, I find it much smoother than before. Thanks.

I think is an addon issue.

cheers

hi markosc try the attached dtb

Quote from markosc

However, I have an issue with the Netflix plugin. When I activate VP9, the videos appear slow and the quality doesn't seem to be 720p. The CPU usage goes up to 220%. It seems smoother if I choose H264; however, the range is between 18 to 28 fps and sometimes it plays slowly. The CPU goes up to 350%, it appears smoother, but the image looks washed out and doesn't seem like 720p.

Hi markosc, it's a known issue, unfortunately. There are some addons, such as Disney+, which for some reason (maybe widevine license) use hardware acceleration for decoding. The Netflix addon does not, so the decoding is via software and with a single thread. For the moment I recommend lowering the playback quality. In libreelec 10 the clocks (cpu/gpu) were higher, but I realized that unfortunately due to the heat, the throttling caused artefacts. I'm trying to find a solution.

Hi usr4864,

it's a reboot of the box? or Kodi? which device tree do you use? Is the generic one or the one for your box?

I'll ask you if you can send me a log because maybe I can get the wifi/Bluetooth working too

missing firmware, in the next build your wifi should work

Can you please tell me if, also checking with Android, your board also has Bluetooth? What is the name of your box (not board)? Do the LEDs work well? Do you try to see by switching to other device trees if your box already has a good configuration?

I want to make a specific device tree, but I need this information.

Quote from anjarys

Hi, attached remote config for greenet.txt

Thank you so much.

Quote from anjarys

And it would be nice if you add wifi driver for SV6256P on your next build, too?

No working driver for now. I'll suggest to use ethernet, or external usb wifi dongle.

Hi fsdonato, please share a new log. The WiFi chip is supported by the kernel with a little patch, so maybe the fix is easy.

anjarys if you have a working remote mapping, please share the results. I'll add your remore config on my next build

Quote from FurmanSK

Anything major relating to h265/HEVC or 4k?

Only the switch from U-Boot legacy --> U-Boot mainline.

Quote from chewitt

LibreComputer are upstream champions so I would expect their boards to work correctly.

board works correctly but ddr3 clock is set to 330mhz(https://github.com/u-boot/u-boot/…r4-666.dtsi#L26) that is too low for 4k contents. A ddr3 clock scaler exists, but without someone that upstream a driver, ddr3 clock is fixed and initialized at boot.

sorry FurmanSK, busy at work.

Keep in mind that libreelec use U-Boot mainline (not the legacy one with proprietary blobs that maybe librecompurer folks suggests).

So the low DDR clock is defined in the device tree for roc-cc of U-Boot mainline source code.

You can try libreelec 10 where U-Boot legacy and binary blobs are used in place of the mainline and see if there are some differences.

Hi all,

a new build of libreelec 11 available with:

- mesa 23.3.0-rc4 and dav1d 1.3.0

- added esp8089 and bcm43342 wireless driver (not tested because I don't have such chip)

- tune ssv6051p wireless driver

- fix Bluetooth driver on t95d box

- ddrbin v1.11

- tune CPU and DDR3 scaling governor

- various fixes and improvements

The build is very stable but some features are missing (like NAND).

My build of Libreelec 11 has some breaking changes that make it incompatible with previous Libreelec 10 builds. In other words, there is no easy way to upgrade your Libreelec 10 setup to Libreelec 11.

Cheers

Michele

fsdonato  markosc with this build I've made some experiments regarding wifi (missing driver and speed problem with ssv6051p). Please try and let me known

Hi fsdonato,

I'll do my best to support various hardware, but regarding kodi addons, I'll not guarantee because it's out of my scope.

Quote from fsdonato

Error "simple iptv one or more items failed"

Sadly I've not found the error in your logs.

However, I discovered that perhaps there is hope for your WiFi. I'm compiling a patch created by jock2 that should help. I will let you know

markosc is the wifi 6051p? because it could also depend on the CPU/DDR clocks which in this version of libreelec are lower (heat and optimizations that make overclocking less useful). I've made some improvements that I hope to release soon and that you might try. this is because libreelec 10 and libreelec 11 practically share the same kernel code (obviously adapted to the latest kernel versions)

Hi fsdonato,

unfortunately, the r29s are very particular as boards. jock2 fixed them up recently because he had one available. If you can't do without wifi, I recommend getting a USB adapter because if I remember correctly, there are no usable drivers for that chip.

But I'll try to do something.

Cheers

Hi MIKMXIII,

Quote from MIKMXIII

but I only noticed a lowering of the volume power with my soud bar compared to libreelec 10.

connected with analogic port?

Quote from MIKMXIII

then its remote control also works but the bluthoot key doesn't work.

sorry, but I don't understand. Are you talking about the remote control of the box or the sound bar? Which bluetooth button?

Hi FurmanSK,

I've builted a version of bootloader with 534Mhz ddr4.

So first make a backup of your installation and after

- download this bootloader https://ilmich.libreelec.tv/rk3328/u-boot-rockchip.bin

- flash it in your bootmedia (from a linux machine or directly in a ssh session of your libreelec installation)

dd if=u-boot-rockchip.bin of=${BOOT_DISK} bs=32k seek=1

where ${BOOT_DISK} is your boot device (for example /dev/mmcblk0)

If works you should see an higher pll_dpll in clk_summary.

Let me known.

Michele

I need to recheck with my boards, but

    pll_dpll                          1        1        0   664000000          0     0  50000         Y
       dpll                           1        1        0   664000000          0     0  50000         Y
          clk_ddr                     2        2        0   664000000  

this should be the clock of ddr. Internally clock is divided by 2 so your ram frequency is 332Mhz.

I imagine that the GUI is also not very fluid, especially at high resolutions.

Without the drivers I mentioned, one way to overclock the RAM is via bootloader. In practice, when the bootloader initializes the RAM it tries to use a higher clock. This can create problems because high clocks need a higher voltage (which the DMC manages automatically).

I'll try to study this official build and see if I can do something, but I can't guarantee because I have no way to try.

Hi FurmanSK,

share the output of

cat /sys/kernel/debug/clk/clk_summary

if this sysfs entry exists, it will show info about every hardware clock on your board.

Overclock is a bit harder because it depends on what the official builds for rk3328 contain.

In the soc rk3228 (and I believe in others too) there is a ddr controller called dmc (dynamic memory controller) which can manage the frequency of the ddr chips at runtime (scaling it up and down).

To work it needs legacy blobs and driver which I imagine (but I don't know) are excluded from the official builds.

On rk3228 works because my build is unofficial and I've assembled such legacy pieces.

I'm not an expert of others rockchip socs, but with rk3228 (not the same of the one discussed in this thread) the only boards that can handle 4k contents are the ones with ddr3 and clock rate >= 600mhz.

maybe can be useful to check also type and clock of DDR RAM.

Hi all,

a new build of libreelec 11 available with:

- mesa 23.2.1

- support for OneTv Lite box (thanks to usr4864 and jock2)

- support for more boxes (from libre10)

- various fixes and improvements

The build is very stable but some features are missing (like NAND).

My build of Libreelec 11 has some breaking changes that make it incompatible with previous Libreelec 10 builds. In other words, there is no easy way to upgrade your Libreelec 10 setup to Libreelec 11.

Michele

great! Thanks for sharing your remote mapping.
